It is possible to work with an Atoll document connected to a Microsoft Access database even if Microsoft Access is not installed on the computer.
1.4 Supported Installation Configurations Depending on your requirements, Atoll can be installed in a: •
Standalone configuration: Atoll installed on each individual user computer with a fixed licence key plugged in each computer.
•
Workstation‐based multi‐user configuration: Atoll installed on each individual user computer on a network with a floating licence management server that allocates licence tokens to Atoll sessions run by users on their computers.
•
Server‐based multi‐user configuration: Atoll installed on servers connected to user computers and a floating licence management server on a network. The floating licence management server allocates licence tokens to Atoll sessions run by the users on the servers. The servers can be Citrix‐based, where users run Atoll sessions on the servers through the Citrix interface.
1.5 Recommended Hardware and Software This section provides guidelines for dimensioning client computers and servers on your network for optimum performance with Atoll. This section lists the recommended hardware and software for: • • • • •
"User Computers" on page 14 "Database Servers" on page 15 "Application Servers" on page 15 "Floating Licence Servers" on page 15 "File Servers" on page 15.

Tablespace of around 100 MB per 10000 transmitters.
1.5.3 Application Servers Application servers are intended for installing and running Atoll, defining user rights, etc. Users can work with Atoll installed on these servers through thin clients such as Remote Desktop or Citrix. The following table lists the required and recommended hardware and software for application servers intended for running with Atoll. Processor
1 quad‐core for 2 to 3 users
RAM
4 GB per user (minimum 8 GB)
Storage
2x146 GB (RAID 1)
Connectivity
Gigabit Ethernet or better
Operating system
Windows Server 2008 R2 SP1 Windows Server 2012
Thin‐client configuration

Virtualisation
VMWare ESXi 4.x or 5.1
The minimum bandwidth between application servers and client computers for satisfactory performance is 300 kbps per user.
1.5.4 Floating Licence Servers The floating licence management server: • • • • •
Must be accessible to all the user computers / Citrix servers on the network in order to provide licence tokens for Atoll sessions. Must have a steady and reliable network connection with user computers / Citrix servers. Must have the HASP licence manager installed and running. For more information, see "Working with Floating Licences" on page 31. Must have the floating licence key plugged in. Can be one of the application servers.
1.5.5 File Servers File servers can store geographic data, path loss matrices, Atoll configuration and initialisation files, and user projects. The required hard disk space has to be determined from the file sizes of these data. Gigabit Ethernet is recommended for connecting user computers, application servers, and file servers. Network bandwidth is required for data exchange between Atoll sessions and file servers. Geographic data and shared path loss matrices should be stored on file servers so that the calculation processes accessing these data do not affect Atoll’s usage and unnecessarily slow down the GUI.

1.6 Recommended Computer Network Architecture The following network architecture recommendations are based on benchmark tests carried out on the network of an average‐size operator, with around 40 to 60 Atoll licences. The results show the requirements in terms of network, hardware, and software. Based on these following, you can set up your network environment for any number of users. The benchmark tests were based on the following scenario: •
Number of end‐users: 40
•
Each user working on an Atoll document with: • • • •
Total number of sites: Number of sites in the calculation area: Per‐sector path loss calculation radius: Path loss calculation resolution:
1660 sites (around 5000 cells) 300 sites (900 cells) 20 km (i.e., matrices of 40 km x 40 km each) 50 m
In order to simulate the average activity of Atoll users, each user is assumed to carry out a "Routine Operation" 5 times during a three‐hour working period. The "Routine Operation" consists in modifying parameters for 40 cells in 30 minutes, recalculating path loss matrices for these 40 cells, and calculating a best server coverage prediction. Although a best server coverage prediction does not require a lot of computer resources for calculations, it requires Atoll to load all the path loss matrices in memory. When the path loss matrices are stored on a file server, as recommended, this operation creates a considerable data transfer activity over the network. The benchmark tests have been based on this simulated data transfer activity. Computer Network Architecture A centralised network architecture is the most widely used network architecture by Atoll users. The figure below shows the recommended architecture along with a per‐user network bandwidth requirement between network components.
Figure 1.1: Recommended Network Architecture and Bandwidth Requirements Citrix XenApp is used to centralise data and balance user loads between servers. A network based on such an architecture with Citrix servers must provide high speed connections between the Citrix servers and the file servers. The required number of Citrix servers depends on the number of users. On the average, one processor per 2 to 3 users is recommended. Thus, the required number of Citrix servers depends on the number of processors and end‐users. Computer Network Dimensioning You should set up your network according to the number of Atoll users, which is related to the size of the planning project. A country‐wide project would have larger network dimensions than a project that covers a city. Link

2.8 Troubleshooting and Other Information Read and follow carefully the instructions in "Installing Atoll Using the Setup Wizard" on page 17 for a smooth installation. If problems occur and you are unable to resolve them with the help of the following information, contact Forsk’s customer support. Microsoft Windows Updates •
•
It is recommended to install new Windows updates. However, it is also recommended to go through the description of each update patch to see whether it might have a negative effect on your system or network. Pay special attention to updates and patches related to networking. It is also recommended to keep the Windows updates uninstall folders, named "$NtUninstall...", under the Windows folder, in case you have to uninstall a certain patch. Some of the update patches might require uninstall folders of older patches to be available for their own installation.
Fixed licence keys •
Fixed licence keys cannot be used with "Server"‐type operating systems. Therefore, you should not install the driver for fixed licence keys on: • • • •
• •
• • •
•
Microsoft Windows Server 2003 Microsoft Windows Server 2008 Microsoft Windows Server 2008 R2 Microsoft Windows Server 2012
The current version of the driver for fixed licence keys (Sentinel SuperPro driver) installed with Atoll is the 7.6.3. If Atoll is unable to access the fixed licence key, even after a clean installation, try reinstalling the Sentinel SuperPro driver manually. The driver’s setup program (SPI763.exe) is copied by the setup to the Sentinel subfolder in the Atoll installation folder if you selected the Driver for Fixed Licence Keys component during the installation. You can also download the driver from http://www.safenet‐inc.com. Restart the computer when asked by the setup. Restarting the computer is necessary for the driver for fixed licence keys to work. If you get a protection key error message, verify that the fixed licence key is correctly plugged in and that the licence has not expired. In case the fixed or the floating licence key becomes unavailable, Atoll will ask the users currently accessing the key to save their open documents before Atoll closes. If the key becomes available again, Atoll will let the users continue working. Do not change the computer’s date.

Atoll 3.2.1 Administrator Manual Chapter 3: Setting Up Distributed Calculation Server
AT321_AM_E1
3 Setting Up Distributed Calculation Server Distributed calculation enables you to distribute the calculation of path loss matrices over many computers in a network. The distributed calculation service is an optional service that can be installed at the same time as Atoll. For more information on installation, see "Installing Atoll and Components" on page 17. A computer on which the distributed calculation service is installed and running is called a distributed calculation server. This computer, the distributed calculation server, is visible to all the other computers on the network through Atoll. You can set up as many distributed calculation servers as required. The distributed calculation service does not have a user interface, and hence has lower memory requirements than Atoll. The distributed calculation server uses the standard Atoll API to exchange data with the path loss calculator and Atoll. The distributed calculation service supports dual‐processor configurations and up to four threads. Any version of Atoll can work with the distributed calculation service of the same or later version. Consequently, any version of the distributed calculation service can work with the same or previous versions of Atoll (versions still maintained by Forsk). For distributed calculation server options available through the Atoll.ini file, see "Distributed Calculation Server Options" on page 163.
3.1 Setting Up Servers When installed, the distributed calculation service automatically starts and remains available as long as the computer is turned on. The service does not require any active user session on the computer, i.e., the service keeps running even when there is no user logged on. The service’s executable (AtollSvr.exe) is installed in the Atoll installation folder. The Atoll distributed calculation service is listed as Atoll Server in the Services management console under Control Panel >Administrative Tools. During calculations, the distributed calculation servers require access to geographic data for calculating the path loss matrices. The distributed calculation service must be run with a user account that has sufficient privileges to access the required data. To modify the user account through which the distributed calculation service is run on a computer: 1. Log on to the computer with a user account with administrator rights. 2. Go to Control Panel > Administrative Tools > Services. 3. In the list of services, right‐click the Atoll Server service. The context menu appears. 4. Select Properties. The Atoll Server Properties dialogue appears.
Figure 3.1: Atoll Server Properties 5. On the Log On tab, enter the user name and password for the user account through which you wish to run this service. 6. Click OK.
27
Atoll 3.2.1 Administrator Manual Chapter 3: Setting Up Distributed Calculation Server
© Forsk 2014
Running More Than One Instance of the Service By default, a single instance of the distributed calculation service is run. You can, however, run up to 9 additional distributed calculation services (a total of 10 including the first one) manually. To manually run additional distributed calculation services, double‐click the AtollSvr.exe file located in the Atoll installation folder. For each new instance of the service, a command prompt window opens. To stop an additional, manually run service, close the command prompt window corresponding to it. Atoll can detect a total of 10 instances of the distributed calculation service. If you run more than 9 additional distributed calculation services, they will not be detected by Atoll and can cause the operating system to stop responding. Stopping and Starting the Distributed Calculation Server To stop the distributed calculation service: 1. Log on to the computer with a user account with administrator rights. 2. Go to Control Panel > Administrative Tools > Services. 3. In the list of services, right‐click the Atoll Server service, and select Stop or Start from the context menu. Uninstalling the Distributed Calculation Server To uninstall the distributed calculation service: 1. Log on to the computer with a user account with administrator rights. 2. Stop the distributed calculation service: a. Go to Control Panel > Administrative Tools > Services. b. In the list of services, right‐click the Atoll Server service, and select Stop from the context menu. 3. Unregister the service: a. Select Start > Run. The Run dialogue appears. b. Type "\AtollSvr.exe /UnregServer". is the path to the Atoll installation folder. c. Click Run. This will remove the distributed calculation service from the computer.
3.2 Setting Up Atoll to Access the Servers To activate distributed calculations in Atoll: 1. Select Tools > Distributed Calculations from the main menu. The Distributed Calculations dialogue appears. 2. Select the Activate distributed calculation check box. a. To use all the available distributed calculation servers, click All. b. To use selected distributed calculation servers only, click Detect. Atoll searches for the available distributed calculation servers on the network. The available distributed calculation servers are listed in the edit box. c. Remove the distributed calculation servers that you do not wish to include. 3. Click OK. The selected distributed calculation servers are now available for path loss calculations.
3.3 Distributed Calculation Process Once distributed calculations have been set up on the calculation server and on the user sides, the path loss calculations run by the user are distributed over the available calculation servers. The calculation process is as follows: 1. Atoll user runs path loss calculations. 2. Atoll sends the needed network data to the available calculation servers. 3. Either Atoll sends the needed geographic data to the calculation servers or the servers access the geographic data on a file server.

Atoll 3.2.1 Administrator Manual Chapter 3: Setting Up Distributed Calculation Server
4. Distributed calculation servers calculate the path loss matrices one by one. Distributed calculation servers that have spare threads start the calculations using these threads. If no thread is available, the request is placed in a queue to wait for a thread to become available. 5. For each calculated path loss matrix, a confirmation is sent to the Atoll session. Any error or warning messages generated are passed back to the Atoll session and displayed in the Event Viewer. If an error occurs on any of the distributed calculation servers, Atoll transfers the calculations back to the local computer. However, to avoid memory saturation, Atoll uses one thread on the local computer and calculates the path loss matrices one by one. It does not attempt creating more than one thread. 6. In order to reduce the amount of data flow in the network, distributed calculation servers send the results directly to the storage location (which can also be on a file server, not necessarily on the user’s computer that requested the calculations). 7. Atoll user can then request the path loss matrices from the file server if they are needed for coverage predictions.

Atoll 3.2.1 Administrator Manual Chapter 4: Managing Licences
AT321_AM_E1
4 Managing Licences Atoll can be used on: • •
Computers with fixed licence keys plugged in to USB slots on the computers themselves, or Computers connected to a licence server with a floating licence key plugged in to a USB port on the server.
The driver for fixed licence keys can be installed at the same time as Atoll. For more information, see "Installing Atoll and Components" on page 17. The software for managing floating licence keys must be installed on a server accessible to the computers on which Atoll is going to be used. For more information, see "Working with Floating Licences" on page 31. For information on the Atoll licence management utility, see "Using the Atoll Licence Manager" on page 33.
4.1 Working with Floating Licences A floating licence key can be used when users work with Atoll on computers on a network. In a floating licence environment, licence keys are not plugged in to each individual user’s computer, but a shared licence key with multiple tokens is available to users through a server. A floating licence server is a computer, accessible to other computers on a network, on which the floating licence management software has been installed and a floating licence key plugged in. The floating licence server can be one of the computers on which Atoll is installed. The floating licence management software and the floating licence key control the number of potential Atoll users. A floating licence system has a defined maximum number of tokens available. This is the maximum number of computers on which Atoll can be run simultaneously. Each computer that runs Atoll takes one token from the floating licence key, even if more than one Atoll session is run on the same computer. The token is released and made available for other users when all the Atoll sessions on the computer are closed. If a computer is connected to a floating licence server and also has a fixed licence key plugged in, the fixed licence key is accessed first. Atoll uses a 3rd‐party floating licence management system called HASP from Aladdin. The floating licence management system includes: • • • • • •
HASP floating licence key: Hardware key programmed with the numbers of tokens available for each module. HASP licence manager: Interface between Atoll and the floating licence key. HASP device driver: Interface between the HASP licence manager and floating licence key. HASP monitor: Enables you to check the number of used and available tokens. nhsrv.ini file: Installed on the floating licence server to enable computers to use tokens. nethasp.ini file: Installed on the computers to facilitate access to the floating licence server. nhsrv.ini and nethasp.ini files are used if they exist. Default settings are used otherwise. •
• • •
You can download the HASP licence manager, the HASP device driver, and the HASP monitor from http://www3.safenet‐inc.com/support/hasp/hasp4/enduser.aspx. Newer versions can be available for download at the website than those provided on the Atoll installation disk. When downloading setup files from the Aladdin website, remember to download setup files for HASP4, not HASP HL. The correct (recommended) version of the device driver setup to download is the one that works with "HASP4 API v8.x or Envelope 12.x". HASP hardware key is supported by Windows 2000 Server and Windows Server 2003 with HASP Licence Manager 8.20 or above.
4.1.1 HASP Licence Manager and Device Driver The HASP licence manager controls the allocation and retrieval of licence tokens available on a floating licence key. It uses the HASP device driver for communicating with the floating licence key. The HASP licence manager can be installed on a computer running Windows 2000 or later. A USB port must be available on the server for plugging in the floating licence key.

•
Do not plug the floating licence key in the server before installing the device drivers. Wait for the HASP licence manager setup to indicate when to plug in the key. If the floating licence server is protected by a firewall, port 475 must be open when using the UDP or TCP protocols. Once the HASP licence manager has been installed, the floating licence key must always remain plugged in. In case the fixed or the floating licence key becomes unavailable, Atoll will ask the users currently accessing the key to save their open documents before Atoll closes. If the key becomes available again, Atoll will let the users continue working. The floating licence key can become unavailable and a key protection error message appears in Atoll if the licence management server is heavily loaded. Check if there is any application running on the server that might be causing the problem. If this is the case, remove any such application from memory. If this is not possible, try changing the latency associated to the HASP licence manager in accessing the key.
Installation and Startup The HASP licence manager, the HASP device driver, and the floating licence key must be installed on the server. The following options should be selected when installing the HASP licence manager: •
Choose "Service" as the type of installation. This means that the licence manager will run as a service, and will be accessible even if there is no user logged on. You can choose to install it as an application, but in that case you will have to run the licence manager manually every time you log on to the server and you will have to stay logged on for the licence server to be available to the Atoll users.
•
Accept automatic driver installation. This will install the HASP device driver required by the HASP licence manager.
•
Once the device driver is successfully installed, plug in the floating licence key.
•
Once installed, start the HASP licence manager. If you selected "Service" as the type of installation, the licence manager will start in service mode. An icon will be available in the task bar. You can access the network communication protocols by double‐clicking this icon. The HASP licence manager window displays a list of supported protocols which can be modified through the Load and Remove menus. Closing this window does not stop the licence manager. The icon remains available in the taskbar as long as the service is running. To stop the HASP licence manager: a. Go to Control Panel > Administrative Tools > Services. b. In the list of services, right‐click the HASP Loader service, and select Stop from the context menu.
•
You can also copy (from the installation CD) or create the nhsrv.ini file on the floating licence server (in the HASP licence manager installation folder). The HASP licence manager settings in this file can be modified according to the your requirements. For more information on the contents of the nhsrv.ini file, see "nhsrv.ini File" on page 32. To restrict access to the HASP licence manager installation folder, you can assign read/ write access rights to this folder to administrators and read‐only rights to end‐users.
HASP Monitor (Optional) You can install the HASP monitor on the floating licence server, or on one or several other computers, to monitor the token allocation and retrieval activity. The HASP monitor displays the list of computers using tokens available on the floating licence key.
4.1.2 nhsrv.ini File The nhsrv.ini file can be used to define a list of computers allowed to request tokens from the floating licence server. File Location If used, the nhsrv.ini file must be located in a folder listed in the system path variable, such as the Windows folder (usually C:\Windows).
32
Atoll 3.2.1 Administrator Manual Chapter 4: Managing Licences
AT321_AM_E1
File Contents The following is a sample of the nhsrv.ini file that shows how to set a list of computers allowed access to the floating licence server. Complete syntax can be found on the HASP installation CD or on the Aladdin website. [NHS_SERVER] ;NHS_IP_LIMIT = [,,,...] ;Specifies the IP addresses of computers served by the licence manager ;Example: 10.1.1.1, 10.1.1.* ;For use, remove the semi-colon before NHS_IP_LIMIT
4.1.3 nethasp.ini File The nethasp.ini file enables Atoll to locate the floating licence server quickly. Without the nethasp.ini file, finding the floating licence server on the network can take a long time. File Location The nethasp.ini file should be located in the Atoll installation folder (recommended). If, for some reason, it is not possible to store the file in the Atoll installation folder, it can be stored in (in the order in which it is searched for by Atoll): •
The Windows folder (usually C:\Windows)
•
A folder listed in the system path variable
A nethasp.ini file located in the Atoll installation folder has priority over any nethasp.ini file located in the Windows folder, which in turn has priority over any nethasp.ini file located in a folder listed in the system path variable. Storing the nethasp.ini file in the Windows folder instead of the Atoll installation folder can be useful if you have more than one version of Atoll installed, and you wish to access the same floating licence server. This avoids making a copy of the file in each Atoll installation folder. File Contents The following is a sample of the nethasp.ini file with the minimum required information. Complete syntax can be found on the HASP installation CD or on the Aladdin website. [NH_COMMON] NH_IPX = Disabled
;Use the IPX protocol - Enabled or Disabled
NH_NETBIOS = Disabled
;Use the NETBIOS protocol - Enabled or Disabled
NH_TCPIP = Enabled
;Use the TCP/IP protocol - Enabled or Disabled
[NH_TCPIP] NH_SERVER_ADDR = 3CT000J
;(a)IP address of the floating licence server
NH_TCPIP_METHOD = UDP
;(b)Send TCP or UDP packets
NH_USE_BROADCAST = Disabled
;Use TCP/IP broadcast - Enabled or Disabled
a.
b.
It is recommended to enter the server name within the domain. For example, for servername.domainname.com, enter servername only. Only one server name is supported in the nethasp.ini file. For HASP Licence Manager 8.20 and later, Aladdin recommends UDP as the default TCP/IP method.
• •
Remove the NH_SESSION and NH_SEND_RCV entries from the nethasp.ini file if these exist. These fields define the timeout delays depending to the network. They can be useful in slow networks and should be set only if required.
4.2 Using the Atoll Licence Manager Atoll Licence Manager enables you to monitor, troubleshoot, and update licence keys. You must not use the licence manager without full instructions and details from Forsk customer support. Modifying parameters in the licence manager without proper input from Forsk customer support can damage your fixed or floating licences and block access of Atoll users to the licences.

AT321_AM_E1
A purchased Atoll licence corresponds to a particular Atollversion. There is no time limit on using this version. However, yearly maintenance must be purchased in order to access newer versions with updates and bug fixes. When you purchase maintenance, Forsk reprograms your licence keys to allow access to new versions. The Time bomb date is the end date for maintenance. When the time bomb date passes, the licence key stops working. You can then choose to either purchase maintenance for the next year, and benefit from the new features and bug fixes, or have the licence key reprogrammed without maintenance for the next year, in which case users can continue working with the existing version. Atoll can inform you about the approaching time bomb date 30 days in advance. This alert can be configured through the Atoll.ini file. • • • •
Do not attempt to modify the Time bomb settings on the fixed licence key. Contact Forsk’s customer support. Do not change the computer’s date.
Under Profile signature, the PID (profile signature or ID) is the encrypted description of the user rights available on the key. Each key has a unique PID. Under Current profile summary, all of the above information is summarised.
4.2.2 Updating Licence Keys Atoll licence manager enables administrators to update licence keys by loading new key programming data from ALIC files provided by Forsk. To update a licence key, you must have the ALIC file sent by Forsk. Do not attempt to reprogram a licence key without full information and support from Forsk customer support.
To update a licence key: 1. Close all Atoll sessions. Atoll reads licence information from the key at the start of each session. This information is kept in memory as long as a session is running. If a licence key is updated while a session is still running, the running session will not read the updated licence information from the key and will expire according to the old licence information. 2. Go to the Atoll installation folder. 3. Run Lic.exe. The licence manager opens (see Figure 4.1 on page 34). 4. Under Available licences, select the key to update. If the key does not appear in the available licences list, check that it is plugged in to your computer. 5. Under Key programming, click Load. The Open dialogue appears. 6. Select the ALIC file provided by Forsk. 7. Click Save. The key is updated.
4.2.3 Testing Licence Keys The Atoll licence manager enables administrators to test licence keys. To test a licence key: 1. Close Atoll. 2. Go to the Atoll installation folder. 3. Run Lic.exe. The licence manager opens (see Figure 4.1 on page 34). 4. Under Available licences, select the key to test. If the key does not appear in the available licences list, check that it is plugged in to your computer. 5. Under Key programming, click Test. The Key test dialogue appears.

Figure 4.2: Test Key Dialogue 6. In the Key test dialogue, under Modules, select the module that you wish to test. 7. Click Test. The test shows whether the selected module is available on the key or not. Never test a module for a future date. If you enter a future date when testing a key, this can reduce the time left for using the key.
4.2.4 Reducing the Number of Module Tokens in ALIC Files ALIC files are used by ForskAlcatel‐Lucent to program fixed or floating licence keys. ALIC files consist of a prefix which includes either the letter A (for floating licence keys) or R (for fixed licence keys) followed by the reference number of the key. One ALIC file corresponds to one unique key with the same reference number on its sticker. OEM clients can create new ALIC files, containing reduced numbers of module tokens, from an existing ALIC file. The ALIC files containing reduced numbers of module tokens can then be used for programming floating licence keys allowing the use of only the selected modules. The following sections describe how you can activate this feature and use it for creating reduced token ALIC files.
4.2.4.1 Activating the Option in the Licence Manager The feature is available through the Licence Manager (Lic.exe). To activate this feature, add the following lines in the Atoll.ini file before running Lic.exe: [RestrictAlicModuleCount] AD384D8F-93EF-481D-B007-8F5B7E0033BC = 1
4.2.4.2 Reducing the Number of Module Tokens Once you have activated the feature, you can use the licence manager to reduce the number of modules allowed on a new ALIC file as follows: 1. Close all Atoll sessions. 2. Run the licence manager. For more information, see "Using the Atoll Licence Manager" on page 33. A fixed or floating licence key must be plugged in to the computer on which you are running the licence manager. This key is required for opening the licence manager window. The ALIC file that you will create will not be for this key. The dongle for which you are going to create the new ALIC file with the reduced number of tokens should be blank and not plugged in to any computer. 3. Click the Reducing programming file tokens button. The Open dialogue appears. 4. Select the ALIC file from which you wish to create another ALIC file with a reduced number of tokens. 5. Click Open. The Module Restriction dialogue appears. 6. In the Module Restriction dialogue, set the number of tokens of each module that you wish to allow in the new ALIC file. You can only reduce the numbers of tokens. To reduce the number of the Base modules, you must first reduce the corresponding numbers of other modules. 7. Click Generate. A new ALIC file is generated with the numbers of module tokens that you selected. This file is located in the same folder as the original ALIC file.
36
Atoll 3.2.1 Administrator Manual Chapter 4: Managing Licences
AT321_AM_E1
8. Close the licence manager. 9. Make a backup copy of the original ALIC file. 10. Remove the ".restricted" extension from the new ALIC file name.
4.2.4.3 Programming a Blank Licence Key Using the Restricted ALIC File Once you have generated the new ALIC file with the reduced numbers of module tokens, you can programme a new blank licence key using this file. To program the licence key with the new ALIC file with reduced numbers of tokens: 1. Close all Atoll sessions. 2. Plug the licence key in to the computer. If it is a floating licence key, set the ADDR_SERVER in the nethasp.ini file equal to the name of your computer. To check that the key is available: a. Run Lic.exe. b. Under Available licences, select the blank key. The Modules and licences section should be empty for the blank key. c. Close Lic.exe. 3. Double‐click the ALIC file. A message will appear indicating that the programming was successful. 4. Check the new contents of the key with Lic.exe. If the contents of the key are correct, you can send the key to your customer. Forsk sends a new ALIC file every year to update the time bomb and maintenance dates. One year after this first programming, after receiving the ALIC corresponding to the key, the same process has to be carried out using the new ALIC file, and the generated ALIC files have to be sent to the customers to enable them to update their keys.

Atoll 3.2.1 Administrator Manual Chapter 5: Managing Databases
AT321_AM_E1
5 Managing Databases In Atoll, you can work with standalone documents, i.e., documents without any back‐end database, or with documents connected to databases. Standalone documents are more portable, however a back‐end database is required when working in a multi‐user environment. In multi‐user environments, several users work on the same project and a central data storage is necessary for keeping the data modifications made by a team of radio planning and optimisation engineers. Atoll enables you create databases, upgrade them to newer versions, archive and refresh data with databases, manage and resolve data conflicts, and create and work with multi‐level databases. A database server can store one or more databases. For example, a GSM, a UMTS, and a microwave links database can be stored on the same database server using the same RDBMS (Oracle, for example). In this chapter, the following are explained: • • • • • • • •
"Atoll Database Templates" on page 39 "Customising Atoll Database Structures" on page 40 "Atoll Management Console" on page 42 "Creating New Databases" on page 43 "Upgrading Existing Databases" on page 45 "Working With a Multi‐level Databases" on page 49 "Setting Database Access Privileges" on page 53 "Managing Data Modifications History" on page 54
5.1 Atoll Database Templates All the technology modules available in Atoll (GSM, UMTS, LTE, CDMA2000, TD‐SCDMA, WiMAX, Wi‐Fi, and Microwave Radio Links) are based on database templates. These templates are used for creating Atoll documents with the appropriate data structure required for planning for any technology. Databases (using RDBMS) can then be created from any Atoll document. These databases are hence also based on the data structure defined by the Atoll database templates. In each new major release, database templates undergo modifications required to support new features. These modifications are applied to existing Atoll documents and databases by Atoll and the Atoll Management Console, respectively. It is also possible to upgrade an existing database manually, but due to the complex nature of the upgrade process, it is highly recommended to use the Atoll Management Console for upgrading existing databases. Each database template is an MS Access MDB file located in the templates folder in the Atoll installation folder. For the list of tables and fields, and their relationships, in each database template, see these chapters in the Data Structure Reference Guide: • • • • • • • • •
Chapter 1: "GSM GPRS EDGE Data Structure" Chapter 2: "UMTS HSPA Data Structure" Chapter 3: "CDMA2000 Data Structure" Chapter 4: "LTE Data Structure" Chapter 5: "3GPP Multi‐RAT Data Structure" Chapter 6: "3GPP2 Multi‐RAT Data Structure" Chapter 7: "TD‐SCDMA Data Structure" Chapter 8: "WiMAX and Wi‐Fi Data Structure" Chapter 9: "Microwave Links Data Structure" Database template files must not be modified without consulting Forsk customer support.

BLOB: Binary large object If you export the contents of an Atoll document, already connected to a database, to another RDBMS (for example, if you export a document connected to an Oracle database to SQL Server), some field types will be converted according to the above table. This conversion does not have any impact on the document in Atoll. For more information on the Atoll Management Console and upgrading databases, see "Atoll Management Console" on page 42 and "Upgrading Existing Databases" on page 45, respectively.
5.2 Customising Atoll Database Structures Atoll database structures can be customised by: • • •
Adding custom fields to data tables, Setting user‐defined default values for fields, and Setting user‐defined choice lists for text fields.
Custom fields, as well as user‐defined default values and choice lists for standard and custom fields, are stored in the CustomFields table. Adding Custom Fields to Data Tables Custom fields can be added to data tables at different stages keeping in mind that: •
•
•
Custom fields added directly to the Atoll database templates (MDB files), using Microsoft Access 2003, will be available in all new Atoll documents created from that template. A new database created by exporting such a document will also contain these custom fields. Custom fields added to an Atoll document through the Atoll user interface will not be automatically added to the corresponding Atoll database template. However, a new database created by exporting such a document will contain these custom fields. For more information on adding custom fields to Atoll documents through the user interface, see the User Manual. Custom fields added to an Atoll database will be available in all new Atoll documents created from that database.
To add a custom field to a data table: 1. Add the custom field to the definition of the data table by defining its name, type, and size. 2. Add a corresponding record in the CustomFields table and enter values for each of the following fields: Field
User Interface Caption
TABLE_NAME
40
Description Database name of the data table that contains the field
COLUMN_NAME
Name
Database name of the field
DEFAULT_VALUE
Default value
User‐defined default value (optional)
CHOICE_LIST
Choice list
User‐defined choice list for text fields (optional)
Atoll 3.2.1 Administrator Manual Chapter 5: Managing Databases
AT321_AM_E1
Field
User Interface Caption
Description
CAPTION
Legend
Caption of the field as it will appear in the user interface (optional but recommended)
GROUP_NAME
Group
Semicolon‐separated list of the names of groups to which the field belongs (optional)
CHOICE_TYPE
Restricted
1: Custom field only accepts values listed in the choice list 0: Custom field accepts values other that those listed in the choice list
DISPLAY_TYPE
Read‐only
1: Custom field is read‐only in the user interface 0: Custom field is modifiable in the user interface
Custom fields are for information only and are not taken into account in any calculation. You can find these fields on the Other Properties tab of an object type’s Properties dialogue. Setting User‐defined Default Values for Fields You can set your own default values for standard as well as custom fields using the CustomFields table. User‐defined default values entered in the CustomFields table have precedence over the predefined default values. To enter a user‐defined default value for any field, add a new record in the CustomFields table and enter values for each of the following fields: Field
User Interface Caption
TABLE_NAME
Description Database name of the data table that contains the field
COLUMN_NAME
Name
Database name of the field
DEFAULT_VALUE
Default value
User‐defined default value
For floating point default values, make sure that all the users have the same decimal symbol.
Setting User‐defined Choice Lists for Text Fields You can set your own choice lists for standard as well as custom text fields using the CustomFields table. User‐defined choice lists entered in the CustomFields table have precedence over the predefined choice lists. To enter a user‐defined choice list for any text field, add a new record in the CustomFields table and enter values for each of the following fields: Field
User Interface Caption
TABLE_NAME
Description Database name of the data table that contains the text field
COLUMN_NAME
Name
Database name of the text field
CHOICE_LIST
Choice list
Choice list items, one per line
For example, you can replace the default choice list available for the SUPPORT_INFO field in the Sites table with a different list of options corresponding to the different types of towers and pylons that may exist in your network. • •
You can enter one of the choice list items in the DEFAULT_VALUE in order to set a default value for the text field. For custom text fields, you can set the CHOICE_TYPE to 1 if you want the custom text field to only accept values listed in the choice list. By default, CHOICE_TYPE is considered to be 0 meaning that users are allowed to enter values other than those defined in the choice list.

Select Use the current connection if you want to create a new database using the current user, or select Create a new user and enter a Name and Password to create a new user that will be owner of the new database. If your password must contain special characters, for example, !, ?, etc., type the password inside double quotation marks: "mypassword!" instead of mypassword!
5. Click Next. The Name the database and specify a network type page appears. 6. Enter a Name for the new database and select the Network type. The Network type can be one of the database templates installed with Atoll. Atoll and the Atoll Management Console must have the same version. This means that the Atoll Management Console can create databases based on the database templates installed with Atoll of the same version. 7. Click Next. The Specify units and coordinate systems page appears. 8. Select a Transmission power unit and a Reception threshold unit. 9. Under Coordinate systems, select a Cartographic projection system and the System to be used in the database. 10. Click Next. The Ready to create database page appears. This page provides a summary of the selected parameters. 11. Click Execute. The Atoll Management Console creates the new database with the defined parameters on the selected database server. A database created using the Atoll Management Console contains an ATOLL_ADMIN table with the following structure:

Among other uses, the ATOLL_ADMIN table is used to speed up the database upgrade to the next version. This table stores the data required by the Atoll Management Console for database upgrade. Databases created with Atoll, instead of the Atoll Management Console, and databases that have never been upgraded using the Atoll Management Console contain a smaller ATOLL_ADMIN table, with just the NAME, ATOLL_VERSION, and ATOLL_BUILD fields. Upgrading such databases using the Atoll Management Console can take a long time because the Atoll Management Console must search for the data required for the upgrade in the whole database. For more information on upgrading databases, see "Upgrading Existing Databases" on page 45. All the tables in a database created using the Atoll Management Console (except the COORDSYS and UNITS tables) contain a non‐modifiable, integer DB_RECORD_ID field. This field is used to store the ID of every record in the table. It is not added to Microsoft Access databases.
5.4.2 Creating a New Database Using Atoll You can create new databases in all supported RDBMS using Atoll. To create a new database: 1. Run Atoll. 2. Create a new Atoll document or open an existing one. The new database will be created from this document. 3. Select Document > Database > Export. The Export to a Database dialogue appears. 4. In the Export to a Database dialogue, select the database type in the Save as type list. By setting an option in the Atoll.ini file, you can instruct Atoll to always use a defined database type (MS Access, SQL Server, or Oracle). In this case, the Export to a Database dialogue will be skipped and the database‐specific authentication dialogue will appear immediately. For more information, see "Setting the Type of Database Being Used" on page 167. 5. Depending on the selected database type, enter the user name and password of the database owner. 6. Click Save. Atoll asks whether you want to connect the document to the new database. 7. Click Yes or No. Atoll creates a new database based on the document. A database created using Atoll contains an ATOLL_ADMIN table with the following structure: Field
Type
Description
NAME
Text (50)
The name of the database
ATOLL_VERSION
Text (10)
The current version of Atoll
ATOLL_BUILD

• • •
Before creating the database, make sure that you have defined the coordinate systems and units in the source document. Before creating the database, make sure that you have added any required custom fields. Custom fields of the source document are created in the new database. If you want to add a custom field to the data structure after you have created the database, you will have to add it directly in the database and not through Atoll. Custom fields added to a database are available to users connected to the database when they create a new Atoll document from the database or refresh an existing one.
5.5 Upgrading Existing Databases In each new major release, data structure changes must be made in the database in order to support the new features added in the version. The data structures of standalone Atoll documents, i.e., documents not connected to any database are upgraded when they are opened in the new Atoll version. You can upgrade databases using the Atoll Management Console.

Do not skip a major version of Atoll. For example, if you are currently using Atoll 2.8.x, you should first upgrade the database to Atoll 3.1.x before upgrading to Atoll 3.2.x. Upgrading your database will be simpler if you do not skip a major version. If you skip or have skipped an intermediate major version, you must upgrade your database twice in order to make it compatible with the new version. If you are upgrading a database which was neither created nor already upgraded (at least once) using the Atoll Management Console, see "Upgrading Databases for the First Time" on page 47 first.
The Microwave Radio Links template now supports Radio Series. Similar microwave radios belong to the same radio series. In order to organise the microwave radios (microwave equipment) in radio series before the database upgrade: 1. In Atoll 2.8.x, add a custom field named FAMILY of type Text (50) to the MWEquipments table. 2. Enter the radio series names in this field for each radio, i.e., group the radios of the same series under the same radio series name in the FAMILY field. Without this manual organisation of the microwave radios into radio series, the database upgrade will create one radio series for each microwave radio. To upgrade a database using the Atoll Management Console: 1. In the Atoll Management Console window, in the right pane, right‐click the database that you want to upgrade. The context menu appears. 2. Select Upgrade Database. The Database Update Wizard dialogue appears. The Database Upgrade Wizard displays the current database version and the version to which the database will be upgraded. 3. Click Next. The Name the database page appears. 4. Enter a Name and description for the database. 5. Click Next. The Database Upgrade Wizard reads the database to determine the Atoll database template using which it was created. If there is more than one template corresponding to the network, select the template to be used for the upgrade and click Next. The Atoll Management Console upgrades the database. •
•
If some of the tables in a database have been replaced by views, the Database Upgrade Wizard asks to select the views to upgrade. Select the views that you want the Atoll Management Console to upgrade and click Execute. If, for example, the definition of a view is given by the condition: Select Field1, Field2 from Table1 where (Condition1); The wizard first upgrades the schema of Table1 and then upgrades the definition of the view. The upgraded definition will take the newly added fields into account. When you upgrade a 3GPP Multi‐RAT database, the Atoll Management Console adds any missing tables to the database. For example, a database created by exporting a 3GPP Multi‐RAT document containing only GSM contains only GSM tables. When upgraded, the Atoll Management Console will add the UMTS and LTE tables to the database as well.
Obsolete fields in the data structure are automatically deleted from the database by the Atoll Management Console during the upgrade. If you use the Atoll Management Console’s history management tool, you must repair the upgraded database in order to continue using this tool. For more information, see "Managing Data Modifications History" on page 54. Once the database has been upgraded to the new version, 1. Install the new Atoll versions for the end‐users, and 2. Ask all the end‐users to fully refresh data in their Atoll documents from the database.

Atoll 3.2.1 Administrator Manual Chapter 5: Managing Databases
AT321_AM_E1
When users open their existing documents in the new Atoll version, they are asked whether they want to upgrade the documents’ data structures to the new version or to disconnect the documents from the database. On selecting the upgrade option, Atoll upgrades the document data structures to make them compatible with the new version. Notes on Document Data Structure Upgrade •
• •
• • •
The data structure of an Atoll document not connected to any database is automatically upgraded to the new Atoll version when the document is opened and saved in the new version. Once saved, it is not possible to open the document in an earlier Atoll version. The data structure of an Atoll document connected to a database not yet upgraded to the new version can be upgraded by: • Either opening the document in the new Atoll version, disconnecting it from the database, and saving it in the new version, or • Upgrading the database to the new version and then opening and saving the document in the new Atoll version. Once disconnected from its database, it is not possible to reconnect the document to any database. Obsolete fields in the data structure of a document not connected to any database are automatically deleted by Atoll when the document is saved in the new version. If the database has been upgraded to the new version but an Atoll document connected to the database has not yet been upgraded, it is possible to open the document in the previous Atoll version as read‐only. It is also not possible to interact with the upgraded database (archive, refresh, etc., are not allowed). To make the document write‐accessible in the previous Atoll version, it must be disconnected from the upgraded database.
It is possible to upgrade an existing database manually (not recommended) by adding and deleting tables and fields as required by the new version. For information on manually upgrading a database, see "Upgrading Databases Manually" on page 48. Upgrading Databases for the First Time If you want to upgrade a database which was neither created nor already upgraded (at least once) using the Atoll Management Console, you must first upgrade the database to the same version as the current version of the database. This is required so that the Atoll Management console adds the required information to the database to make it upgradable to newer versions. To upgrade the database: 1. Before installing the new version of Atoll, install the Atoll Management Console (if not already installed) compatible with the existing version of Atoll. 2. Upgrade the database (as described in "Upgrading Existing Databases" on page 45) using the Atoll Management Console to the existing version of Atoll. The Atoll Management Console adds additional fields to the ATOLL_ADMIN table and DB_RECORD_ID fields in all the tables, as described in "Creating a New Database Using the Atoll Management Console" on page 43. Once the Atoll Management Console has performed the necessary modifications, you can upgrade the database to the new Atoll version. 3. Install the new version of Atoll and the Atoll Management Console. 4. Upgrade the database (as described in "Upgrading Existing Databases" on page 45), using the new version of the Atoll Management Console, to the new version of Atoll. When a new version of the Atoll Management Console is installed, the setup overwrites the Windows registry key that stores the information about the Admin.dll file, and the existing version of the Atoll Management Console can no longer be used. If you have already installed the new version of the Atoll Management Console, you will have to register the old Admin.dll again, upgrade the database to the existing version, register the new Admin.dll, and upgrade the database to the new version using the new Atoll Management Console. For the Atoll Management Console to be able to recognise obsolete or deleted fields from database tables, it is imperative that the ATOLL_ADMIN table exist in the database. This means that when upgrading a database for the first time using the Atoll Management Console, the database administrator will have to remove the obsolete fields manually. Once the Atoll Management Console has been used to upgrade a database, it will be able to recognise obsolete or deleted fields in the following upgrades.
47
Atoll 3.2.1 Administrator Manual Chapter 5: Managing Databases

Upgrading Databases Manually Due to the complex nature of the database upgrade process, it is highly recommended to use the Atoll Management Console for upgrading existing databases. You should only proceed with a manual upgrade of your database, as described below, if and only if an automatic upgrade using the Atoll Management Console is not possible. The following procedure is not recommended for customised Atoll databases and only suits very simple databases. Parameters and settings (triggers, views, user privileges, custom fields, etc.) defined in advanced database configurations are lost following the manual database upgrade. 1. In the previous version of Atoll, create a new document from the database. 2. In the new version of Atoll, open the document created in step 1. Atoll upgrades the document data structure to make it compatible with the new version. 3. Using the upgraded document, create a new database as explained in "Creating a New Database Using Atoll" on page 45. If you are upgrading your database using a script based on the data structure modifications listed in the Data Structure Reference Guide, you must: • •
Add the ATOLL_ADMIN table to the database. For more information on this table, see "Creating a New Database Using the Atoll Management Console" on page 43. For LTE databases, rename the smart antenna models and equipment as follows: • Delete existing smart antenna equipment ("Optimum Beamforming Smart Antenna") from the SmartAntennas table. • Delete existing smart antenna model ("Optimum Beamformer") from the SmartAntennasModels table. • Create a new smart antenna equipment ("Conventional Beamforming Smart Antenna") in the SmartAntennas table. Set the smart antenna model for this equipment to "Conventional Beamformer."
Adding a Technology in a Multi‐RAT Database A multi‐RAT Atoll document can be based on one or two radio technologies out of a maximum of three (GSM, UMTS, and LTE). Provided such a document has already been exported to a database, you can add a technology to the corresponding database through the Atoll Management Console. 1. Start the Atoll Management Console. 2. When the Atoll Management Console opens, right‐click on Database in the left pane. The context menu appears. 3. Select Register a New Server. The Data Link Properties dialogue is displayed. 4. On the Provider tab, select an OLE DB provider and click Next. 5. On the Connection tab, specify a database in the Select or enter a database name field. 6. Click the Test Connection button. If the connection is successful, click OK to close the Data Link Properties dialogue. 7. Upgrade the database if necessary, as explained in "Upgrading Existing Databases" on page 45. 8. In the right pane, right‐click the database you want to upgrade with an additional technology and select Multi‐RAT: View/Add Technologies. The Technologies in the Multi‐RAT Database dialogue is displayed.
Figure 5.4: Technologies in the Multi‐RAT Database 9. Select the technology you want to add and click OK.

You cannot deselect a technology already present in a multi‐RAT database.
A new record is added to the networks table for each technology added to the database.
5.6 Working With a Multi‐level Databases Atoll Management Console allows you to set up and work with multi‐level databases using Oracle. In this optional database architecture, the master database is not directly accessible to end‐users. Groups of end‐users work with their respective project databases which are in turn connected to the master database. The end‐users archive data to and refresh data from their respective project databases, and the database administrator manages the connections and data exchange between the project databases and the master database. For example, you can have a country‐wide master database and more than one regional project databases. End‐users can here work with their local region’s project database, and would not have to unnecessarily load country‐wide data.
Figure 5.5: Working With a Single Level Database Project databases are intermediate databases created from a common master database. A project database contains the original master database, that remains hidden from the end‐users, and an copy of the master database accessible to the end‐ users. When a user modifies a record, only its accessible copy is modified in the project database. The original value in the master database remains unchanged until the database administrator archives all the modifications from the project databases to the master database.
Figure 5.6: Working With Project Databases Project databases can be used to improve performance and ensure data security and reliability. Instead allowing all the end‐ users to work directly with the master database, one or many project databases can be created with copies of the entire master database or a part of the master database corresponding to a given physical location or region. Creating and working with project databases restricts the number of users who have access to the master database. This reduces the risk of conflicts in the database as only the database administrator can archive modifications from project databases to the master database. For example, if a country‐wide network database is accessible to all end‐users:
49
Atoll 3.2.1 Administrator Manual Chapter 5: Managing Databases
• • • •
© Forsk 2014
The probability of human error increases with the number of users who can modify data. The probability of conflicts increases with the number of users accessing the database. The performance is reduced because the entire network is loaded every time a user accesses the database. For routine city‐wide planning, an end‐user does not require the entire country’s database to be loaded.
Project databases can be created using filters on sites, thus allowing users to work with regional databases. A possible scenario is depicted in the figure below:
Figure 5.7: Multiple Project Databases From a Single Master Database Multi‐level databases can be set up using the Atoll Management Console. In this section, the following are explained: • • •
"Creating Project Databases" on page 50 "Archiving Project Databases to Master Databases" on page 52 "Refreshing Project Databases from Master Databases" on page 53
5.6.1 Creating Project Databases You can create project databases using the Atoll Management Console. For creating a project database, you must have enough rights to be able to create new tables in the master database schema.
To create a project database from an existing master database: 1. In the Atoll Management Console window, in the right pane, right‐click the master database from which you want to create a project database. The context menu appears. 2. Select Create a Project Database. The Project Database Creation Wizard dialogue appears. 3. Click Next. The Specify the server and the owner of the project database page appears. 4. Select the Destination server for the project database. 5. Under Owner, select Current user if you want to create the new project database using the current user, or select Create a new user and enter a User name and Password to create a new user that will be owner of the new project database. Some versions of Oracle let you create a new user through this dialogue but the new user is not assigned DBA rights, which makes the new user unable to create the project database. Therefore, it is recommended to create the new user with DBA rights directly in the database before create the project database using the Atoll Management Console using the new user account. 6. Click Next. The Name the database page appears.

Atoll 3.2.1 Administrator Manual Chapter 5: Managing Databases
AT321_AM_E1
7. Enter a Name and Description for the new project database. 8. Click Next. The Specify the sites to include in the project database page appears. 9. On this page, choose from one of the following options: •
Include all the sites of the master database Select this option if you want to create a project database that contains all the data of the master database.
•
Include a site list contained in the master database Select this option if you want to create a project database containing the network data corresponding to the sites included in a site list of the master database, and select a site list. This option is only available when at least one site list exists in the master database.
•
Select the sites to include using an SQL condition Select this option if you want to create a project database containing the network data corresponding to the sites that verify an SQL condition (for example, sites that have a common parameter or flag), and enter the SQL condition.
•
Include the sites contained within a polygon contained in a file Select this option if you want to create a project database containing the network data corresponding to the sites that are located inside a polygon, and select the file containing the polygon to use.
10. Click Next. The Atoll Management Console creates the new project database with the defined parameters on the selected database server. The project database will have the type PROJECT listed in the Atoll Management Console window.

You can view the details stored in the ATOLL_ADMIN_PRJ table in the project database properties. To view the above details of a project database: 1. In the right pane, right‐click the project database in the list. The context menu appears. 2. Select Properties. The database Properties dialogue appears. 3. The Properties dialogue contains three tabs: • •
•
General tab: The General tab displays the Name, Description, Owner, Type, and Version of the database. Project Database tab: Under Source master database, the Project Database tab displays the Connection settings to and the Owner of the master database. Under Site selection, this tab displays the site filtering Method and Settings used for creating the project database. Statistics tab: The Statistics tab displays the number of records in each table of the project database.
The project database contains a copy of all the original tables of the master database. The names of the original tables are prefixed with "O_". For example, the ANTENNAS table of the master database is stored in the project database under the name O_ANTENNAS. The COORDSYS and UNITS are not copied to the project database because their contents cannot be different from those of the master database. All the tables in a project database contain a non‐modifiable, integer O_RECORD_ID field and a Boolean O_CHANGED field. The O_RECORD_ID field is used to locate records in the master database. Modified records are archived in master database using the O_RECORD_ID of the project database and DB_RECORD_ID of the master database. The O_CHANGED field is set to TRUE for records modified in the project database.
5.6.2 Archiving Project Databases to Master Databases Changes made in the project databases can be archived to the master database using the Atoll Management Console. The Archive dialogue lets you select changes you want to archive. To archive the changes from a project database to its master database: 1. In the Atoll Management Console window, in the right pane, right‐click the project database from which you want to archive changes to its master database. The context menu appears. 2. Select Archive. If pending changes exist, the Archive dialogue appears. The Archive dialogue lists the records of the project database for which the O_CHANGED field is TRUE. 3. In the Archive dialogue, you can do the following: • • • • • •
Select a site list in Filter by site list to filter the pending changes by a site list. Click Archive All to archive all the changes to the master database. Select the check boxes to the left of the changes that you want to archive and click Archive Sel. to archive only the selected changes. Click Undo All to overwrite all the changes in the project database with data from the master database. Select the check boxes to the left of the changes that you want to undo and click Undo Sel. to overwrite only the selected changes in the project database with data from the master database. Select the Check conflicts check box to see whether conflicts occurred during the archive. A conflict occurs when the project database contains a different original value of a field than the current value of the field in the master database. This can occur if the master database has been updated with changes from another source and the project database has not yet been refreshed with data from the master database.

Figure 5.9: Archiving Changes in Master Databases Under Errors, Atoll Management Console displays errors that occurred during archive. 4. Once archive is complete, click Close.
5.6.3 Refreshing Project Databases from Master Databases Project databases can be refreshed with data from the master database using the Atoll Management Console. To refresh a project database with data from its master database: 1. In the Atoll Management Console window, in the right pane, right‐click the project database that you want to refresh with data from its master database. The context menu appears. 2. Select Refresh. If pending changes exist, the Refresh a Project Database dialogue appears. 3. In the Refresh a Project Database dialogue, you can: •
•
Select Refresh unmodified data only to keep any changes in the project database and only update unmodified records from the master database. During the refresh, the Atoll Management Console will reload records from the master database for which the O_CHANGED field is FALSE in the project database. Select Cancel your changes and reload all data from the master database to overwrite modified and unmodified records in the project database with data from the master database.
1. Click OK. The project database is refreshed with data from the master database.
5.7 Setting Database Access Privileges You can assign different levels of privileges to different users for accessing (reading/writing) tables and views of a database. You can grant user privileges for Database, Table, Column, and Row levels keeping the following in mind: •
Database Level: Users trying to create a new Atoll document from a database are provided a list of available databases to select from. The list can be limited to a few databases based on the user connection properties (log in).
•
Table Level: For consistency reasons, all the tables available in an Atoll database must be readable by all the users who have access to the database. However, write access (INSERT, DELETE, UPDATE) can be granted on a limited number of tables.
•
Column Level: Similar to table level, all the columns of all the tables in an Atoll database must be readable and selectable by all the users who have access to the database. Different write permissions can be granted for columns of the tables. For example, custom fields can be assigned read and write permissions without restrictions.
•
Row Level: Row level permissions can be set by defining custom views on Atoll tables. Access to these views can be based on user connection properties (log in), on external table references, or on the geographic locations of sites (e.g., through polygons, or when using the spatial features of databases).
53
Atoll 3.2.1 Administrator Manual Chapter 5: Managing Databases
© Forsk 2014
All of these permissions can be set as regular SELECT, INSERT, UPDATE, and DELETE privileges on database objects. Triggers can also be used to prevent users making certain actions on the database. Different permissions for different users can be granted directly or through database roles. Database roles enable you to define permission templates, which can then be assigned to existing or new users of the database. You can use the Atoll Management Console for defining user access rights to database tables and elements in the Atoll GUI. For more information on managing user access rights, see "Managing User Accounts and Access Rights in Oracle" on page 65.
5.8 Managing Data Modifications History The Atoll Management Console allows you to keep and manage the history of modifications made in the network data by different users. The history management tool keeps track of all the modifications made in the following Atoll tables: Technology
Tracked Tables
GSM GPRS EDGE
Sites, Transmitters, TRGs, TRXs, Repeaters, SecondaryAntennas, Neighbours, NeighboursExt
UMTS HSPA
Sites, Transmitters, CDMACells, Repeaters, SecondaryAntennas, Neighbours, NeighboursExt

You can, however, enable or disable history management for table as required (see "Enabling/Disabling Data Modifications History Management" on page 55 for more information). If you want, you can also purge old data modifications history (see "Purging Old Data Modification Records" on page 56 for more information). The history management tool is available for Oracle databases. The following section describes how to set up the history management tool using the Atoll Management Console.
5.8.1 Setting Up Data Modifications History Management When you set up history management for any database, the Atoll Management Console adds new tables to the database structure. For each tracked table, it adds a corresponding history table that has the same name as the tracked table with the suffix "_H". Each history table has the same structure as the corresponding tracked table, but with the following four additional fields. These fields enable the Atoll Management Console to store the modifications made by users to each tracked table: Field
Type
Description
HISTORY_ID
Integer
A unique ID of the modification history record
MODIFIED_BY
Text (50)
The user who made the modification
MODIFIED_DATE
Date
The date when the modification was made
HISTORY_STATUS
Text (10)
Status of the modification history record
The above fields are also added to all the tracked tables in order to store information about the latest modification. Therefore, opening any tracked table, you can see when a record was last modified, by whom, and the type of modification. To set up data modifications history management for a database: 1. In the Atoll Management Console window, in the right pane, right‐click the database for which you want to set up data modifications history management. The context menu appears. 2. Select Manage Data Modifications History. The Data Modifications History Management dialogue appears. 3. Click Yes when asked whether you want to make your database compatible with the data modifications history tool.
54
Atoll 3.2.1 Administrator Manual Chapter 5: Managing Databases
AT321_AM_E1
The Atoll Management Console updates the database structure to make it compatible with the data modifications history tool. Data modifications history is enabled for the database. Once finished, it opens the Data Modifications History Management dialogue (see Figure 5.10 on page 56). This dialogue lists all the tables for which the data modifications history management has been enabled, the total numbers of records in these tables, and the status of the history management. All the modifications made in the tables listed in "Managing Data Modifications History" on page 54 are stored in the history tables added to the database. If you want, you can disable the data modifications history management for any table. For more information, see "Enabling/ Disabling Data Modifications History Management" on page 55.
5.8.2 Enabling/Disabling Data Modifications History Management You can enable or disable data modifications history management for any table. You can enable or disable history management for each individual table. When history management is enabled for a table, the MODIFIED_BY, MODIFIED_DATE, and HISTORY_STATUS fields are updated with each modification, and a copy of each modification is stored in the history table corresponding to the table. When history management is disabled for a table, the MODIFIED_BY, MODIFIED_DATE, and HISTORY_STATUS fields are still updated with each modification, but the history of modifications is not stored in the corresponding history table. To enable data modifications history management for a table: 1. In the Atoll Management Console window, in the right pane, right‐click the database for which you want to enable data modifications history management. The context menu appears. 2. Select Manage Data Modifications History. The Data Modifications History Management dialogue appears. 3. In the Data Modifications History Management dialogue, right‐click the table for which you want to enable data modifications history management. The context menu appears. 4. Select Enable in the context menu. Data modifications history management is now enabled for this table. The Status in the Data Modifications History Management dialogue is set to OK for this table. To disable data modifications history management for a table: 1. In the Atoll Management Console window, in the right pane, right‐click the database for which you want to disable data modifications history management. The context menu appears. 2. Select Manage Data Modifications History. The Data Modifications History Management dialogue appears. 3. In the Data Modifications History Management dialogue, right‐click the table for which you want to enable data modifications history management. The context menu appears. 4. Select Disable in the context menu. History management is now disabled for this table. The Status in the Data Modifications History Management dialogue is set to Deactivated for this table.
5.8.3 Updating After Data Structure Upgrade When you modify the structure of a tracked database table (for which data modifications history management is enabled), either automatically upgrading your database using the Atoll Management Console, or manually by adding or removing fields, or by modifying a field type, the corresponding data modifications history management table becomes invalid and has to be updated to match the new structure of the tracked table. The Status column of the Data Modifications History Management dialogue shows an error for the tracked table whose history management table does not match its structure. To update the data modifications history management tables: 1. In the Atoll Management Console window, in the right pane, right‐click the database whose tables you want to update. The context menu appears. 2. Select Manage Data Modifications History. The Data Modifications History Management dialogue appears. 3. In the Data Modifications History Management dialogue, right‐click the table that you want to update. The context menu appears. 4. Select Install/Repair in the context menu. The Atoll Management Console repairs the data structure of the history management table to match the structure of the corresponding tracked table.

5.8.4 Purging Old Data Modification Records History management tables store the lists of all the modifications made by all the users. These tables can therefore quickly become very large and require a lot of disk space. You can purge old data modifications history (records) from these tables in order to gain disk space. In this section, the following is explained: • •
"Purging Old Data Modification Records of a Table" on page 56 "Purging Old Data Modification Records of a Database" on page 57.
5.8.4.1 Purging Old Data Modification Records of a Table To purge old data modification records from a history management table: 1. In the Atoll Management Console window, in the right pane, right‐click the database in which you want to purge old data modifications history. The context menu appears. 2. In the context menu, select Manage Data Modifications History. The Data Modifications History Management dialogue appears (see Figure 5.10 on page 56).
Figure 5.10: Data Modifications History Management Dialogue 3. In the Data Modifications History Management dialogue, right‐click the table for which you want to purge old data modifications history. The context menu appears. 4. In the context menu, select Purge. The table record purge dialogue appears (see Figure 5.11 on page 56).

5.9 Appendices The first appendix shows how to use SQL for Oracle database customisation and the second appendix shows how to set up databases for co‐planning taking the example of GSM and UMTS MS Access databases.
5.9.1 Appendix 1: Advanced Customisation You can use SQL in order to manage access to and share the Sites table (example 1), or to restrict the connection to a set of transmitters for some users (example 2). To implement the following two examples, you must log on as the owner of the tables through SQL Plus 8. Example 1: Managing Site Sharing Assumptions: • • • •
Connection string = AtollDB GSM Project account = AtollADMINGSM, password = ADMINGSM UMTS Project account = AtollADMINUMTS, password = ADMINUMTS Common Project account = AtollADMIN, password = ADMIN
To share the Sites table: 1. Create the AtollADMIN.SITES table and copy all sites from AtollADMINGSM.SITES to AtollADMIN.SITES. SQL > connect AtollADMIN/ADMIN@AtollDB; SQL > create table AtollADMIN.SITES as select * from AtollADMINGSM.SITES; SQL > create unique index AtollADMIN_SITES on AtollADMIN.SITES(NAME); 2. Replace the AtollADMINGSM.SITES table by an AtollADMINGSM.SITES view. SQL > connect AtollADMINGSM/ADMINGSM@AtollDB; SQL > drop table AtollADMINGSM.SITES; SQL > connect AtollADMIN/ADMIN@AtollDB; SQL > grant delete on AtollADMIN.SITES to AtollADMINGSM with grant option;
58
Atoll 3.2.1 Administrator Manual Chapter 5: Managing Databases
AT321_AM_E1
SQL > grant insert on AtollADMIN.SITES to AtollADMINGSM with grant option; SQL > grant select on AtollADMIN.SITES to AtollADMINGSM with grant option; SQL > grant update on AtollADMIN.SITES to AtollADMINGSM with grant option; SQL > create view AtollADMINGSM.SITES as select * from AtollADMIN.SITES; 3. Follow the same procedure for UMTS (AtollADMIN.SITES already created). SQL > connect AtollADMINUMTS/ADMINUMTS@AtollDB; SQL > drop table AtollADMINUMTS.SITES; SQL > connect AtollADMIN/ADMIN@AtollDB; SQL > grant delete on AtollADMIN.SITES to AtollADMINUMTS with grant option; SQL > grant insert on AtollADMIN.SITES to AtollADMINUMTS with grant option; SQL > grant select on AtollADMIN.SITES to AtollADMINUMTS with grant option; SQL > grant update on AtollADMIN.SITES to AtollADMINUMTS with grant option; SQL > create view AtollADMINUMTS.SITES as select * from AtollADMIN.SITES; 4. Commit. SQL > commit; Example 2: Managing Users by Postal Code To restrict access to transmitters for some users by postal code: 1. Add a ‘POSTCODE’ field to the SITES table. SQL > alter table SITES add (POSTCODE number); 2. Rename the SITES table to be able to hide it by a view. SQL > rename SITES to PRIVATE_SITES; 3. Create a POSTCODETABLE table to link users and postcodes (one user can be linked to several postcodes). SQL > create table POSTCODETABLE (USERNAME varchar2(30), POSTCODE number); You can fill this table using this instruction. SQL > insert into POSTCODETABLE values (‘USER1’, 75); 4. Create a view owned by this user hiding the actual SITES table through these commands. SQL > create view SITES as select * from PRIVATE_SITES where POSTCODE in (select POSTCODE from POSTCODETABLE where USERNAME =USER) with check option; "with check option" is very important as it specifies that insert and update operations performed through the view must result in rows that the view query can select. 5. Hide the TRANSMITTERS table, so that Atoll can only select transmitters whose associated sites are present in the SITES view. SQL > rename TRANSMITTERS to PRIVATE_TRANSMITTERS; SQL > create view TRANSMITTERS as select * from PRIVATE_TRANSMITTERS where SITE_NAME in (select NAME from SITES); 6. Commit. SQL > commit;

The error message "ORA‐01402: view WITH CHECK OPTION ‐ clause violation" appears if you try to archive a record that does not match the project.
5.9.2 Appendix 2: Setting Up Databases for Co‐planning Two co‐planning approaches are possible in Atoll: •
Co‐planning GSM, UMTS, and LTE using a unified multi‐technology data structure, i.e., working with a 3GPP Multi‐RAT document.
•
Co‐planning any two radio technologies (GSM, UMTS, LTE, CDMA2000, TD‐SCDMA, and WiMAX), with two separate data structures, by linking Atoll documents.
In terms of database, while the first approach provides an integrated multi‐technology co‐planning environment, the second requires setting up sharing of the Sites table between the databases of the two technologies being co‐planned. The Sites table must be shared between the databases of the two technologies being co‐planned so that the sites where sectors of both technologies are installed are listed only once in a common Sites table. In other words, the Sites tables in the databases of the two technologies must be views of a common Sites table. This section describes table sharing between GSM and UMTS, although the same description can be applied to any two radio technology modules of Atoll You can create views to share tables that have the same structure in the databases of the two technologies being co‐planned, i.e., the Sites and Antennas tables. In the following, we assume that the Sites tables of the GSM and UMTS documents contain the same data and that two users, named GSMUser and UMTSUser in this example, exist in the databases. To set up a shared Sites table for a GSM‐UMTS co‐planning project in Oracle or SQL Server: 1. Make backups of the GSM and UMTS documents. 2. Open the GSM document in Atoll. 3. Delete all the transmitters from the Transmitters table and all the sites from the Sites table. 4. Export the GSM document to the database by entering the user name and password for GSMUser. 5. Log in as GSMUser to the database. 6. Delete the Sites table. 7. Open the UMTS document in Atoll. 8. Export the UMTS document to the database by entering the user name and password for UMTSUser. 9. Log in as UMTSUser to the database. 10. Right‐click the Sites table and select Create a View from the context menu. The Create View dialogue appears. a. Enter Sites as the view name. b. Enter GSMUser as the name of the schema which will contain the view. c. Select Table as object type. d. Enter UMTSUser as the name of the schema you want to use. e. Select Sites as the object used to model the view. 11. Click Create. The view of the Sites table from UMTSUser is created in GSMUser. The GSMUser Sites table is now the same as UMTSUser Sites table. 12. Set up user privileges for the Sites view in GSMUser to allow each user to Import, Update, Delete, and Select. To set up a shared Sites table for a GSM‐UMTS co‐planning project in Microsoft Access: 1. Make backups of the GSM and UMTS documents. 2. Open the GSM document in Atoll. 3. Delete all the transmitters from the Transmitters table and all the sites from the Sites table. 4. Export the GSM document to a Microsoft Access database (GSM.mdb). 5. Open GSM.mdb in Microsoft Access. 6. Delete the Sites table. 7. Open the UMTS document in Atoll 8. Export the UMTS document to a Microsoft Access database (UMTS.mdb). 9. Open GSM.mdb in Microsoft Access.

10. In Microsoft Access 2003 and earlier, select File > Get External Data > Link Tables. In Microsoft Access 2007 and later, select External Data > Access Database. 11. In Microsoft Access 2003 and earlier, the Link dialogue appears. Select UMTS.mdb. In Microsoft Access 2007 and later, the Get External Data ‐ Access Database dialogue appears, specify UMTS.mdb as data source and select Link to data source by creating a linked table. 12. Click OK. The Link Tables dialogue appears. 13. Select the Sites table. 14. Click OK. Microsoft Access creates a Sites table in GSM.mdb which is linked to the Sites table in UMTS.mdb. The tables contain the same data. Once the linked Sites table has been created in the GSM database, you have to define the relations of this table with the other tables in the database. See the Data Structure Reference Guide for detailed information on database tables. • •
The UMTS Sites table has more fields than the GSM Sites table. Therefore, you should replace the GSM Sites table with the UMTS one. When you upgrade one by one the databases that share the Sites table, any triggers that you might have set on the Sites table of the database that is upgraded first might be overwritten by the triggers set on the Sites table of the database upgraded last. In order to avoid the triggers being overwritten, you can rename the triggers on the Sites table of the database upgraded first (by adding, for example, the database technology as prefix to the trigger names) before upgrading the other database(s).
Ensuring Database Consistency Between Linked Documents When users work with two Atoll documents and databases at the same time, it is important to have a protection mechanism against database inconsistencies. If a user archives the changes made in one document but forgets to archive the changes made in the other, this can create inconsistencies between the two networks. To ensure database consistency, you can save or archive the linked documents at the same time, i.e., when a user saves or archives one document, Atoll automatically saves or archives the other. This can be done using a macro triggered by the save or archive operation.

Atoll 3.2.1 Administrator Manual Chapter 6: Multi‐user Environments
AT321_AM_E1
6 Multi‐user Environments A multi‐user environment is where more than one user work simultaneously on an Atoll project, sharing data over a network. In large, structured multi‐user environments, groups of users can work on specific parts of a common, large‐scale project. For example, different user groups can work on different regions of a country‐wide network. In this chapter, the following are explained: • • •
"Setting Up Multi‐user Environments" on page 63 "Components of Multi‐user Environments" on page 63 "Managing User Accounts and Access Rights in Oracle" on page 65
6.1 Setting Up Multi‐user Environments The general process of setting up a multi‐user environment is described below. Each component is described in detail in "Components of Multi‐user Environments" on page 63. 1. Create the master Atoll document with the required network data and geographic data. For more information, see "Master Atoll Document" on page 64 and "Shared Geographic Data" on page 64. 2. Export the master Atoll document to a new database and keep the document connected to the new database. For more information, see "Master Database" on page 64. 3. Create the private path loss matrices folder for the master Atoll document and calculate the private path loss matrices. For more information, see "Shared Path Loss Matrices" on page 65. 4. Create user Atoll documents from the master database. For more information, see "User Atoll Documents" on page 65. 5. In the user Atoll documents, add the required geographic data and set the master Atoll document’s private path loss matrices folder as the shared path loss matrices folder of the user documents. • •
The Atoll administrator should regularly update the shared path loss matrices. As the users work on the network and archive changes in the database, the Atoll administrator should regularly run data integrity checks on the master Atoll document after loading modified data from the master database. For more information, see "Appendix 1: Checking Data Integrity" on page 69.
6.2 Components of Multi‐user Environments Figure 6.1 on page 63 shows the components of a multi‐user environment.

In this section, the following are explained: • • • • •
"Master Atoll Document" on page 64 "Master Database" on page 64 "Shared Geographic Data" on page 64 "Shared Path Loss Matrices" on page 65 "User Atoll Documents" on page 65
6.2.1 Master Atoll Document It is the source Atoll document that contains the entire project’s network data. It is created and maintained by the Atoll administrator. This document is initially used to create the radio network database with which all the end‐users work. The master Atoll document allows the administrator to globally manage all the data shared by the end‐users. The master Atoll document is also used for calculating path loss matrices for the transmitters of the entire network and keeping the path loss matrices up to date with the user modifications to the radio network data. The document also contains the required geographic data for path loss calculations. Geographic data are usually located on file servers and linked to the document, not embedded in the ATL file. The private path loss matrices of this document are used as shared path loss matrices by the end‐users. The shared path loss matrices folder is usually located on a file server accessible to all the users on the network. For exceptionally large networks, you can also work with more than one master Atoll document (for example, one master document per region). However, the multi‐user environment set up remains the same. Master Atoll documents should not have redundant radio network data (same sites, for example), and should ideally cover different geographical regions. For more information on regionalisation, see "Appendix 2: Database Regionalisation" on page 70. If you wish to add custom fields in the Atoll document, you should first add the field in the database, and then update your Atoll document from the database. Custom fields added in an Atoll document connected to a Microsoft Access database are automatically added to the database. However, this is not the case with other RDBMS, such as Oracle.
6.2.2 Master Database The master database stores the radio network data shared by all the end‐users. It can be created by exporting the radio network data in the master Atoll document to a database from Atoll (for more information, see "Creating a New Database Using Atoll" on page 45). An empty database can also be created using the Atoll Management Console, and populated with data later on (for more information, see "Creating a New Database Using the Atoll Management Console" on page 43). Only radio network data are stored in the database, i.e., sites, transmitters, antennas, etc. Parameters related to geographic data files, their paths, folder configurations, prediction definitions, zones, traffic maps, measurements can be stored in user configuration files (see "Configuration Files" on page 117 for details). For large networks, you can subdivide the network’s master database into regions. For more information on regionalisation, see "Appendix 2: Database Regionalisation" on page 70. For more information on database management, see "Managing Databases" on page 39. The recommended database server configuration is provided in "Recommended Hardware and Software" on page 14. The same database server can be used to store one or more master databases corresponding to different technologies. For example, a GSM database and a UMTS database can be stored on the same database server using the same RDBMS (Oracle, for example).
6.2.3 Shared Geographic Data Geographic data files are usually stored on a file server accessible to and shared by all the users working on the same network. User configuration files (CFG or GEO) are used to store the parameters related to geographic data. For more information, see "Configuration Files" on page 117. The administrator can set up different user configuration files (CFG) for separate user groups. User configuration files can be created so that only the geographic data required by a user are loaded. It is possible to load a user configuration file automatically when running Atoll. User configuration files can be shared and exchanged between users working on the same project. For more information, see "Atoll Command Line Parameters" on page 24. Geographic data files are usually large files, and it is recommended that these be stored externally and not embedded in Atoll documents. The recommended file server configuration is provided in "Recommended Hardware and Software" on page 14.

Atoll 3.2.1 Administrator Manual Chapter 6: Multi‐user Environments
AT321_AM_E1
If users modify geographic data locally, for example edit clutter or traffic in their respective projects, they should store these modified geographic data locally so that the modifications do not impact other users.
6.2.4 Shared Path Loss Matrices Shared path loss matrices are usually stored on a file server accessible to and shared by all the users working on the same project. These path losses are calculated using the master Atoll document by the Atoll administrator. The private path loss matrices of the master Atoll document are used as shared path loss matrices by the end‐users. The Atoll administrator is the owner of the shared path loss matrices, and must have read/write access to the shared path loss matrices folder. End‐users should have read‐only access to this folder. It is the administrator’s duty to regularly update the master Atoll document with the modifications made to the master database by the end‐users, and to calculate the shared path loss matrices using the master Atoll document on a routine basis. This task can be carried out using a macro. For more information, see "Appendix 3: Calculating Path Loss Matrices" on page 70. Shared path loss matrices are available for use in calculations to all the end‐users. However, end‐users are not allowed to modify the shared path loss matrices. The shared path loss matrices must be unlocked in order for users to be able to work with them. You can check whether path loss matrices are unlocked in the Propagation tab of the Transmitters folder’s properties dialogue.
6.2.5 User Atoll Documents User Atoll documents are created from the master database. These can contain the entire project network data or only a part of it. User documents are the working documents of the Atoll end‐users connected to the master database, the geographic data, and the shared path loss matrices folder. You should load data from the master database in each user Atoll document and save it before setting the shared path loss matrices folder for the document. For any modifications made by end‐users in their Atoll documents that render some shared path losses invalid, Atoll calculates the invalid path loss matrices locally for the end‐users and stores them in their private path loss matrices location. Shared path loss matrices are only used in calculations if valid private path loss matrices are not available. Therefore, in order to use shared path loss matrices, you must delete the corresponding private path loss matrices. If users are going to work on regions of a network, the regionalisation should be set up before creating the user documents. For more information on regionalisation, see "Appendix 2: Database Regionalisation" on page 70. If you wish to add custom fields in the Atoll document, you should first add the field in the database, and then update your Atoll document from the database. Custom fields added in an Atoll document connected to a Microsoft Access database are automatically added to the database. However, this is not the case with other RDBMS, such as Oracle.
6.3 Managing User Accounts and Access Rights in Oracle The Atoll Management Console enables you to create and delete database user accounts, edit user account information, and define user access rights to different components of a project such as database tables, and radio data and parameters in Atoll. In order to be able to manage user accounts and access rights using the Atoll Management Console, you first have to make the database compatible with the user management tool. This is done automatically when the user management tool is run on a database for the first time. The database has to be of the same version as the Atoll Management Console being used to manage user accounts and access rights. To make your database compatible with the user management tool: 1. In the Atoll Management Console window, right‐click the database whose user accounts you wish to manage. 2. Select Manage Users. The User Management dialogue appears (see Figure 6.2 on page 66). 3. Click Yes when asked whether you want to make your database compatible with the user management tool. The Atoll Management Console adds a GUIUserRights table in the database with the following structure: Field
Type
Description
ATOLL_USER
Text (50)
Name of the user account

Field
Type
Description
RIGHTS
Memo
Semi‐colon separated set of interface access rights
Each user’s interface access rights are stored in a unique record in the GUIUserRights table. The contents of the RIGHTS field have the following syntax: RADIOPARAMS;CALCPARAMS;PROPAGMODELS;PASSWORD The syntax is explained in detail in "Defining Database and Interface Access Rights" on page 66. If interface access rights are not defined for a database, i.e., the GUIUserRights table does not exist, all the users have unrestricted access to the Atoll interface. If interface access rights are defined for a database, and a user creates a document from the database or opens a document connected to the database, Atoll retrieves the interface access rights for the user when he enters his user name and password to access the database. If the database is not reachable, the user is not listed in the GUIUserRights table, or if the password is not correct, the user’s interface access rights are set to read‐only by default (for more information, see "Defining Database and Interface Access Rights" on page 66). If the user is listed in the GUIUserRights table, his interface access rights are read and applied to the Atoll interface (table grids and properties dialogues). A message is displayed in the Event Viewer window to inform the user of his interface access rights. It is possible to remove interface access restrictions by disconnecting the document from the database. However, a disconnected document cannot be reconnected to the database. The GUIUserRights table is also stored in the Atoll document, and is updated when the document is saved. Hence, users can work on their documents without actually being connected to the database, and still have their usual interface access rights applied in the document. Atoll does not ask for the user name and password when a document is opened using the API. The interface access rights stored in the document are used.
When database connection properties are modified for a document, for example, when a different user enters his user name and password in the connection properties, Atoll reads and applies the interface access rights defined for the new user.
6.3.1 Defining Database and Interface Access Rights For any existing user account, you can set the database and Atoll interface access rights using the Atoll Management Console. To manage database and Atoll interface access rights for an existing user account: 1. In the Atoll Management Console window, right‐click the database whose user accounts you wish to manage. 2. Select Manage Users. The User Management dialogue appears (see Figure 6.2 on page 66).
Figure 6.2: User Account and Access Rights Management Dialogue 3. Under Atoll projects, select the project for which you want to manage user accounts.

4. Under List of users, select the user account whose database and interface access rights you want to set. Users who have database access rights in the selected database are marked with the green icon ( ). Users who do not have any database access rights in the selected database (Category = No Access) are marked with the red icon ( ). Locked (deactivated) user accounts are marked with a yellow lock icon ( ). For more information on locked user accounts, see "Creating and Editing User Accounts" on page 68. You can use the Filter list to display: ), without access (

All users: Users with access (
• • • •
Users with access ( ) Administrators: Users with administrator rights among the users with access Standard users: Users with standard rights among the user with access Read‐only users: Users with read‐only access rights among the users with access
5. Under Database rights, you can select a database access Rights category: • • •
•
No access: User without read and write access to the database. The database is not visible to these users and they are not allowed to create Atoll documents based on this database. Read‐only: Users allowed to create Atoll documents from the database but without write permissions to any table of the database, i.e., users cannot archive changes made in the Atoll document to the database. Standard: Users with read and write access to some tables of the database. These tables include radio network data tables including sites, transmitters, cells, subcells, repeaters, remote antennas, secondary antennas, intra‐ and inter‐technology neighbours and exceptional pairs, site and transmitter lists, microwave point‐to‐point, point‐ to‐multipoint, and multi‐hop links, microwave repeaters, microwave hubs. Administrator: Users with read and write access to all the tables of the database.
Database access rights are stored in the user account properties in Oracle. If you are working with an RDBMS other than Oracle, you will not be able to set database access rights. You can, however, still set interface access rights as explained below. 6. Under Interface rights, you can select interface access rights for: •
Access to radio data: • Full: (RADIOPARAMS = ALL) Users with read and write access to all the tables and properties dialogues. • Standard: (RADIOPARAMS = STD) Users with read and write access to radio network data tables and properties dialogues including sites, transmitters, cells, subcells, repeaters, remote antennas, secondary antennas, intra‐ and inter‐technology neighbours and exceptional pairs, site and transmitter lists, microwave point‐to‐point, point‐to‐multipoint, and multi‐hop links, microwave repeaters, microwave hubs. • Read‐only: (RADIOPARAMS = NONE) Users with read‐only access to tables and properties dialogues, i.e., users are not allowed to modify radio network data and parameters. •
•
Database access rights and access rights to radio data in Atoll can be set independently. For example, a user can have full access rights in the interface but not be allowed to archive changes to the database. However, access rights in the interface should only be granted if the user has at least read‐only access to the database.
•
Access to calculation settings: • All: (CALCPARAMS = ALL) Users with read and write access to all coverage predictions, their calculation settings, and to microwave calculation settings (Models, Objectives, and Clutter Categories tabs of the Properties dialogue of the Microwave Radio Links folder). • Standard: (CALCPARAMS = STD) Users with access to customised coverage predictions only, and allowed to modify coverage conditions and display settings. These users do not have access to the microwave calculation settings mentioned above. • Customised only: (CALCPARAMS = NONE) Users with access to customised coverage predictions only, but not allowed to modify coverage conditions and display settings. These users do not have access to the microwave calculation settings mentioned above.
•
Access to propagation models: • Full: (PROPAGMODELS = ALL) Users with read and write access to all propagation models and their properties. • Read only: (PROPAGMODELS = NONE) Users with read‐only access to the properties of all the propagation models. Adding and deleting propagation models is also not allowed.
•
Password confirmation: • Yes: (PASSWORD = STD) Atoll will ask users for password when opening a document connected to this database or creating a new document from this database. • No: (PASSWORD = NONE) Atoll will not ask users for password when opening a document connected to this database or creating a new document from this database.

Atoll 3.2.1 Administrator Manual Chapter 6: Multi‐user Environments
AT321_AM_E1
This feature is particularly useful after a major Atoll upgrade or after tables were added as a result of a project customization, and for all unforeseen reasons which can require fixing user database permissions. The permissions reset process does not remove any object privileges which assigned prior to rebuilding the database. It just looks for new objects and assigns permissions based on existing user profiles ("Administrator", "Standard" or "Read‐only"). To reset user permissions: 1. Open the database for which you want to reset user permissions in the Atoll Management Console window. 2. Under Database rights, click on the Reset button. 3. Acknowledge the message informing you about the rebuilding process duration. The duration of the database rebuilding process depends on the number of users and on the database processing speed.
6.4 Appendices The following appendices provide additional information on: • • • •
"Appendix 1: Checking Data Integrity" on page 69 "Appendix 2: Database Regionalisation" on page 70 "Appendix 3: Calculating Path Loss Matrices" on page 70 "Appendix 4: Path Loss Matrices From Different Sources" on page 71
6.4.1 Appendix 1: Checking Data Integrity Atoll includes data consistency and integrity checking tools that allow you to check data consistency between the different Atoll tables (Sites, Transmitters, etc.). It is recommended that the Atoll administrator runs data integrity checks regularly on the master Atoll document after it is updated with data modifications in the master database. To perform data integrity check: •
In Atoll, select Document > Data Audit > Integrity Check. Atoll searches for records with integrity problems which can occur with objects that have foreign keys. Integrity problems occur when records refer records that do not exist. For example, transmitters located on sites that do not exist in the Sites table, transmitters referring to an antenna that does not exist in the Antennas table, etc.). Records with integrity problems can be deleted when found.
To perform undefined record check: •
In Atoll, select Document > Data Audit > Undefined Record Check. Atoll searches for undefined records such as sites without transmitters, transmitters without subcells, TRXs, and neighbours in GSM, transmitters without cells, and cells without neighbours in UMTS, CDMA2000, TD‐SCDMA, LTE, WiMAX, and Wi‐Fi. Atoll lists all the undefined records found in the Event Viewer.
To perform duplicate record check: •
In Atoll, select Document > Data Audit > Duplicate Record Check. Atoll searches for records that have the same identifier. For example, sites with the same name, transmitters with the same name, etc. Atoll lists all the duplicate records in the Event Viewer.
To perform microwave data check: 1. In Atoll, select Document > Data Audit > Microwave Link Data Check. The Microwave Data Check dialogue appears. 2. In the Microwave Data Check dialogue, select the data to check. 3. Select List all the checks to list all the checks in the Event Viewer. 4. Click OK. Atoll searches the microwave links tables for problems related to the selected checks. Atoll lists the problems found in the Event Viewer. If you fix any problems in the Atoll document, you must archive the changes in the database in order to fix the problems for all the users working with that database.

6.4.2 Appendix 2: Database Regionalisation You can subdivide the network into regions in the following ways: •
Static regionalisation using multi‐level databases Static regionalisation can be based on site lists, SQL filters, or geographic zones in the form of filtering polygons. Static regionalisation is carried out by creating project databases from the master database, i.e., multi‐level databases as explained in "Working With a Multi‐level Databases" on page 49. Static regionalisation requires manual synchronisation between the master database and the regional project databases using the Atoll Management Console. In a multi‐level database environment, end‐users work with project databases, refreshing and archiving data as they continue to work on their respective regions of the network. Data archive and refresh between the project databases and the master database are performed by the administrator alone. • •
•
Advantage: High performance. Disadvantage: Manual Synchronisation between the master and the project databases.
Dynamic regionalisation using Oracle Spatial or Oracle Locator Dynamic regionalisation can be based on Oracle Spatial, which does not create separate regional databases from the master database, but rather lets the different users work with the master database directly while managing their access privileges according to their user connection properties. In an Atoll multi‐user environment, you can create such regionalisation without installing Oracle Spatial. You can implement this solution using Oracle Locator, which is provided in the standard Oracle installation. Specific documents explaining how to set up this regionalisation, using Oracle, in any Atoll master database are available on demand from Forsk. These documents provide scripts for creating different types of users, e.g., the administrator, advanced user, read‐only user, etc., and give examples of how to set up regions in the network and how to assign user rights to each region. • •
Advantage: Once set up, does not require administrator intervention. Disadvantage: Slow performance (archiving data in the database takes a long time).
6.4.3 Appendix 3: Calculating Path Loss Matrices You can calculate only the invalid path loss matrices or all the path loss matrices in Atoll or using a macro. You should only calculate the shared path loss matrices when they are not being accessed by users.
To calculate invalid path loss matrices only: 1. Right‐click the Transmitters folder. The context menu appears. 2. Select Calculations > Calculate Path Loss Matrices. Atoll calculates path loss matrices for all active transmitters in the folder or subfolder. Only invalid and nonexistent matrices are calculated. To calculate all the path loss matrices (valid and invalid): 1. Right‐click the Transmitters folder. The context menu appears. 2. Select Calculations > Force Path Loss Matrix Calculation. Atoll calculates all the path loss matrices for all active transmitters in the folder or subfolder. You can write a script or macro to update path loss matrices automatically at regular intervals. The script or macro should: 1. Start Atoll (Start). 2. Open the master Atoll document (Open). 3. Refresh the contents of the document with data from the database (Refresh). 4. Calculate path loss matrices (Calculate). 5. Save the master Atoll document (Save). 6. Close Atoll (Exit). A path loss update macro is available from Forsk on demand.
70
Atoll 3.2.1 Administrator Manual Chapter 6: Multi‐user Environments
AT321_AM_E1
You should also make regular backups of the master Atoll document. The above macro could also create a backup ATL file of the master Atoll document on a regular basis. This file can be overwritten daily, whenever path losses are calculated.
6.4.4 Appendix 4: Path Loss Matrices From Different Sources Atoll calculates path loss matrices and creates path loss matrix storage files using the propagation models assigned to transmitters. Atoll can also work with path loss matrices calculated by other tools. To use path loss matrices from different sources, make sure that the path loss matrices are: • • •
Available in a format compatible with Atoll. File formats are described in "Path Loss Matrix File Format" on page 92. Stored at the location set in the Atoll document. Valid. If the path loss matrices are not valid, Atoll will automatically calculate them the next time they are used. Path loss matrices calculated by other tools should include antenna pattern attenuation (i.e., should be masked) in order to be consistent with the path loss matrices calculated by Atoll.
The shared path loss matrices architecture can contain path loss matrices from different sources. The Pathloss.dbf file provides the means to manage several sources of path loss matrices. This file stores, among other information, the validity status and the location (path) of the path loss matrix files for each transmitter. Let us assume that users of group A wish to work with the path loss matrices generated by Atoll only, and users of group B wish to work with path loss matrices generated by a different tool for a part of the network and with path loss matrices generated by Atoll where the matrices from the other tool are not available. Let us assume that the shared path loss matrices folder where Atoll stores the generated path loss matrices files is C:\Path_Loss_Internal, and the folder where the other tool stores its path loss matrices is C:\Path_Loss_External. The Pathloss.dbf file in the Path_Loss_Internal folder will store the path to the LOS files for each transmitter in the network. This folder can be set as the shared path loss matrices folder in the ATL files of group A users. To set up the shared path loss matrices folder for group B users, you must create a new folder with a Pathloss.dbf file in it. This folder can be called C:\Path_Loss_Mixed. The Pathloss.dbf file in this folder can be a copy of the Pathloss.dbf file in the Path_Loss_Internal folder with the paths to the LOS files modified. For example, if the path loss matrices generated by the other tool include Transmitter_1, the Pathloss.dbf file in the Path_Loss_Mixed folder will have all the same entries as Pathloss.dbf file in the Path_Loss_Internal folder except for the path for the Transmitter_1 path loss matrices file. Figure 6.4 on page 71 explains this concept.
Figure 6.4: Path Loss Architecture for Multiple Source Path Loss Matrices Once the Pathloss.dbf file in the Path_Loss_Mixed folder is updated with the correct paths corresponding to the different transmitters, the Path_Loss_Mixed folder can be set as the shared path loss matrices folder in the ATL files of group B users. If a group B user changes some parameters which make some path loss matrices invalid, Atoll will recalculate the private path loss matrices with the propagation models assigned to the transmitters. The external path loss matrix will no longer be used.

Atoll 3.2.1 Administrator Manual Chapter 7: Coordinate Systems and Units
AT321_AM_E1
7 Coordinate Systems and Units 7.1 Coordinate Systems A map or a geo‐spatial database is a flat representation of data collected over a curved surface. Projection is a means of producing all or part of a spheroid on a flat surface, which cannot be done without distortion. It is up to the cartographer to choose the characteristic (distance, direction, scale, area, or shape) that he wants to produce accurately on a flat surface at the expense of the other characteristics, or to make a compromise on several characteristics. The projected zones are referenced using cartographic coordinates (metre, yard, etc.). Two projection methods are widely used: •
•
The Lambert Conformal‐Conic Method: A portion of the earth is projected on a cone conceptually secant at one or two standard parallels. This projection method is useful for representing countries or regions that have a predominant east‐west expanse. The Universal Transverse Mercator (UTM) Method: A portion of the earth is projected on a cylinder tangent to a meridian (which is transverse or crosswise to the equator). This projection method is useful for mapping large areas that are oriented north‐south.
A geographic system is not a projection, but a representation of a location on the surface of the earth in geographic coordinates (degree‐minute‐second, gradient) with the latitude and longitude with respect to a meridian (e.g., Paris for NTF system and Greenwich for ED50 system). Locations in a geographic system can be converted into other projections. References: 1. Snyder, John. P., Map Projections Used by the US Geological Survey, 2nd Edition, United States Government Printing Office, Washington, D.C., 313 pages, 1982. 2. http://www.colorado.edu/geography/gcraft/notes/gps/gps_f.html 3. http://www.epsg.org/Geodetic.html 4. http://geodesie.ign.fr/contenu/fichiers/documentation/pedagogiques/ transfo.pdf (French)
7.1.1 Definition of a Coordinate System A geographic coordinate system is a latitude and longitude coordinate system. The latitude and longitude are related to an ellipsoid, a geodetic datum, and a prime meridian. The geodetic datum provides the position and orientation of the ellipsoid relative to the earth. Cartographic coordinate systems are obtained by transforming each (latitude, longitude) value into an (easting, northing) value. A projection coordinate system is obtained by transforming each (latitude, longitude) value into an (easting, northing) value. Projection coordinate systems are geographic coordinate systems that provide longitude and latitude, and the transformation method characterised by a set of parameters. Different methods might require different sets of parameters. For example, the parameters required for Transverse Mercator coordinate systems are: • • • • •
The longitude of the natural origin (central meridian) The latitude of the natural origin The False Easting value The False Northing value A scaling factor at the natural origin (central meridian)
Basic definitions are presented below. Geographic Coordinate System The geographic coordinate system is a datum and a meridian. Atoll enables you to choose the most suitable geographic coordinate system for your geographic data. Datum The datum consists of the ellipsoid and its position relative to the WGS84 ellipsoid. In addition to the ellipsoid, translation, rotation, and distortion parameters define the datum. Meridian The standard meridian is Greenwich, but some geographic coordinate systems are based on other meridians. These meridians are defined by the longitude with respect to Greenwich.

Ellipsoid The ellipsoid is the pattern used to model the earth. It is defined by its geometric parameters. Projection The projection is the transformation applied to project the ellipsoid of the earth on to a plane. There are different projection methods that use specific sets of parameters. Projection Coordinate System The projection coordinate system is the result of the application of a projection to a geographic coordinate system. It associates a geographic coordinate system and a projection. Atoll enables you to choose the projection coordinate system matching your geographic data.
7.1.2 Types of Coordinate Systems in Atoll Depending on the working environment, there can be either two or four coordinate systems used in Atoll. If you are working with stand‐alone documents, i.e., documents not connected to databases, there are two coordinate systems used in Atoll: • •
Projection coordinate system Display coordinate system
If you are working in a multi‐user environment, Atoll uses four coordinate systems: • • • •
Projection coordinate system for the Atoll document Display coordinate system for the Atoll document Internal projection coordinate system for the database Internal display coordinate system for the database
Projection Coordinate System The projection coordinate system is the coordinate system of the available raster geographic data files. You should set the projection coordinate system of your Atoll document so that it corresponds to the coordinate system of the available raster geographic data. You can set the projection coordinate system of your document in the Options dialog. All the raster geographic data files that you want to import and use in an Atoll document must have the same coordinate system. You cannot work with raster geographic data files with different coordinate systems in the same document. If you import vector geographic data (e.g., traffic, measurements, etc.) with different coordinate systems, it is possible to convert the coordinate systems of these data into the projection coordinate system of your Atoll document. The projection coordinate system is used to keep the coordinates of sites (radio network data) consistent with the geographic data. When you import a raster geographic data file, Atoll reads the geo‐referencing information from the file (or from its header file, depending on the geographic data file format), i.e., its Northwest pixel, to determine the coordinates of each pixel. Atoll does not use any coordinate system during the import process. However, the geo‐referencing information of geographic data files are considered to be provided in the projection coordinate system of the document. Display Coordinate System The display coordinate system is the coordinate system used for the display, e.g., in dialogs, in the Map window rulers, in the status bar, etc. The coordinates of each pixel of geographic data are converted to the display coordinate system from the projection coordinate system for display. The display coordinate system is also used for sites (radio network data). You can set the display coordinate system of your document in the Options dialog. If you import sites data, the coordinate system of the sites must correspond to the display coordinate system of your Atoll document. If you change the display coordinate system in a document which is not connected to a database, the coordinates of all the sites are converted to the new display system. If the coordinate systems of all your geographic data files and sites (radio network data) are the same, you do not have to define the projection and display coordinate systems separately. By default, the two coordinate systems are the same.
74
Atoll 3.2.1 Administrator Manual Chapter 7: Coordinate Systems and Units
AT321_AM_E1
Internal Coordinate Systems The internal coordinate systems are the projection and the display coordinate systems stored in a database. The projection and display coordinate systems set by the administrator in the central Atoll project are stored in the database when the database is created, and cannot be modified by users. Only the administrator can modify the internal coordinate systems manually by editing the entries in the CoordSys and the Units tables. All Atoll documents opened from a database will have the internal coordinate systems of the database as their default projection and display coordinate systems. When exporting an Atoll project to a database, the currently chosen display coordinate system becomes the internal display coordinate system for the database, and the currently chosen projection coordinate system becomes the internal projection coordinate system for the database. Although Atoll stores both the coordinate systems in the database, i.e., the projection and the display coordinate systems, the only relevant coordinate system for the database is the internal display coordinate system because this coordinate system is the one used for the coordinates of sites (radio network data). Users working on documents connected to a database can modify the coordinate systems in their documents locally, and save these changes in their documents, but they cannot modify the coordinate systems stored in the database. If you change the display coordinate system in a document which is not connected to a database, the coordinates of all the sites are converted to the new display system. If you change the display coordinate system in a document which is connected to a database, the coordinates of all the sites are converted to the new coordinate system in the Atoll document locally but not in the database because the internal coordinate systems cannot be changed. Atoll uses the internal coordinates systems in order to keep the site coordinates consistent in the database which is usually accessed by a large number of users in a multi‐user environment.
7.1.3 Coordinate Systems File Format The Coordsystems folder located in the Atoll installation directory contains all the coordinate systems, both geographic and cartographic, offered in the tool. Coordinate systems are grouped by regions. A catalogue per region and a "Favourites" catalogue are available in Atoll. The Favourites catalogue is initially empty and can be filled by the user by adding coordinate systems to it. Each catalogue is described by an ASCII text file with .cs extension. In a .cs file, each coordinate system is described in one line. The line syntax for describing a coordinate system is: Code = "Name of the system"; Unit Code; Datum Code; Projection Method Code, Projection Parameters; "Comments" Examples: 4230 = "ED50"; 101; 230; 1; "Europe - west" 32045 = "NAD27 / Vermont"; 2; 267; 6, -72.5, 42.5, 500000, 0, 0.9999643; "United States - Vermont" You should keep the following points in mind when editing or creating .cs files: • •
The identification code enables Atoll to differentiate coordinates systems. In case you create a new coordinate system, its code must be an integer value higher than 32767. When describing a new datum, you must enter the ellipsoid code and parameters instead of the datum code in brackets. There can be 3 to 7 parameters defined in the following order: Dx, Dy, Dz, Rx, Ry, Rz, S. The syntax of the line in the .cs file will be:
Code = "Name of the system"; Unit Code; {Ellipsoid Code, Dx, Dy, Dz, Rx, Ry, Rz, S}; Projection Method Code, Projection Parameters; "Comments" •
• •
There can be up to seven projection parameters. These parameters must be ordered according to the parameter index (see "Projection Parameter Indices" on page 78). Parameter with index 0 is the first one. Projection parameters are delimited by commas. For UTM projections, you must provide positive UTM zone numbers for north UTM zones and negative numbers for south UTM zones. You can add all other information as comments (such as usage or region).
Codes of units, data, projection methods, and ellipsoids, and projection parameter indices are listed in the tables below.

7.1.4 Creating a Coordinate System in Atoll Atoll provides a large default catalogue of coordinate systems. However, it is possible to add new geographic and cartographic coordinate systems. New coordinate systems can be created from scratch or initialised based on existing ones. To create a new coordinate system from scratch: 1. Select Document > Properties. The Properties dialogue opens. 2. Select the Coordinates tab. 3. Click the Browse button (
) to the right of Projection. The Coordinate Systems dialogue appears.
4. Click New. The Coordinate System dialogue appears.
78
Atoll 3.2.1 Administrator Manual Chapter 7: Coordinate Systems and Units
AT321_AM_E1
5. In the Coordinate System dialogue: a. Select the coordinate systems catalogue to which you want to add the new coordinate system. b. Under General, enter a Name for the new coordinate system and select a Unit. In Use, you can enter comments about its usage. Atoll assigns the code automatically. c. Under Category, select the Type of coordinate system. Enter the longitude and latitude for a geographic coordinate system, or the type of projection and its set of associated parameters for a cartographic coordinate system (false easting and northing, and the first and second parallels). d. Under Geo, specify the meridian and choose a Datum for the coordinate system. The associated ellipsoid is automatically selected. You can also describe a geodetic datum by selecting "" in the Datum list. In this case, you must select an Ellipsoid and enter parameters (Dx, Dy, Dz, Rx, Ry, Rz, and S) needed for the transformation of the datum into WGS84. 6. Click OK. The new coordinate system is added to the selected coordinate system catalogue. To create a new coordinate system based on an existing system, select a coordinate system in the Coordinate Systems dialogue before clicking New in step 4. The new coordinate system is initialised with the values of the selected coordinate system.
7.2 Units In the Atoll documents, you can define measurement units for reception, transmission, antenna gain, distance, height and offset, and temperature. You can accept the default measurement units, or you can change them using the document properties dialogue. Transmission and Reception Power Units Depending on the working environment, Atoll can use either one or two measurement units for the transmission/reception power. If you are working with stand‐alone documents, i.e., documents not connected to databases, there is only one measurement unit used in Atoll for display. It corresponds to the transmission/reception power unit defined in the Atoll document. If you are working in a multi‐user environment, Atoll uses two measurement units: •
•
A measurement unit for display in the Atoll document. It corresponds to the transmission/reception power unit defined in the current Atoll document. It is used for the display in the dialogues and in the tables, e.g., reception thresholds (coverage prediction properties, microwave link properties, etc.), and received signal levels (measurements, point analysis, coverage predictions, microwave link properties, etc.). An internal measurement unit for the database. The internal unit is the transmission/reception power unit stored in the database. It corresponds to the transmission/reception power unit used in the master Atoll document when the database is created. Users working in documents connected to a database can modify the transmission/reception power unit and save this change in their documents locally, but they cannot modify the internal power unit stored in the database. Only the administrator can modify it manually by editing the entry in the Units tables.
Antenna Gain Units Depending on the working environment, Atoll can use either one or two measurement units for the antenna gain. If you are working with stand‐alone documents, i.e., documents not connected to databases, there is only one measurement unit used in Atoll for display. It corresponds to the antenna gain unit defined in the Atoll document. If you are working in a multi‐user environment, Atoll uses two measurement units: • •
A measurement unit for display in the Atoll document. It corresponds to the antenna gain unit defined in the current Atoll document and it is used for the display in the dialogues and in the tables. An internal measurement unit for the database. The internal unit is the antenna gain unit stored in the database. It corresponds to the antenna gain unit used in the master Atoll document when the database is created. Users working in documents connected to a database can modify the antenna gain unit and save this change in their documents locally, but they cannot modify the antenna gain unit stored in the database. Only the administrator can modify it manually by editing the entry in the Units tables.
Distance Units Atoll uses the distance unit defined in the current Atoll document as display unit of the distances in the dialogues, in the tables, and in the status bar. Metre is used as the internal measurement unit for the distance in all Atoll documents whether they are connected to databases or not. The internal measurement unit is not stored in the database and cannot be changed.
79
Atoll 3.2.1 Administrator Manual Chapter 7: Coordinate Systems and Units
© Forsk 2014
Height and Offset Units Atoll uses the height and offset unit defined in the current Atoll document as display unit of the heights and the offsets in the dialogues, in the tables, and in the status bar. Metre is used as the internal measurement unit for the heights and offsets in all Atoll documents whether they are connected to databases or not. The internal measurement unit is not stored in the database and cannot be changed. Temperature Units Atoll uses the temperature unit defined in the current Atoll document as display unit of the temperatures in the dialogues and in the tables. Degree Celsius is used as the internal measurement unit for the temperature in all Atoll documents whether they are connected to databases or not. The internal measurement unit is not stored in the database and cannot be changed.
7.3 BSIC Format Depending on the working environment, there can be either one or two types of BSIC formats. If you are working with stand‐ alone documents, i.e., documents not connected to databases, there is only one BSIC format: •
Display BSIC format
If you are working in a multi‐user environment, Atoll uses two type of formats: • •
Display BSIC format for the Atoll document Internal BSIC format for the database
The display format is used for the display in dialogs and tables. You can set the display format for your document from the Transmitters folder’s context menu. The internal format is the BSIC format stored in a database. The BSIC format set by the administrator in the central Atoll project is stored in the database when the database is created, and cannot be modified by users. Only the administrator can modify the internal format manually by editing the corresponding entry in the Units tables. All Atoll documents opened from a database will have the internal format of the database as their default BSIC format. Users working on documents connected to a database can modify the format in their documents locally, and save this change in their documents, but they cannot modify the format stored in the database.

9 Radio Data Formats Radio network data in Atoll includes the following, depending on the technology used in the network being planned: • • • •
• • • • • • • •
Site: The geographic location of transmitters (sectors, installed antennas, other equipment). A site can have one or more transmitters. Antenna: The radiation patterns and gains for antennas installed at transmitters. Transmitter: A group of radio devices installed at a site with there transmission/reception characteristics (antennas, feeders, TMAs, other equipment). A transmitter can have one or more cells or subcells. Cell: An RF carrier available at a transmitter in UMTS, CDMA2000, TD‐SCDMA, LTE, WiMAX, and Wi‐Fi networks. A cell is fully defined by the "transmitter‐carrier" pair. Each cell in these networks is independent, i.e., has its own identifier, power levels, performance characteristics. TRX: An RF carrier available at a transmitter in GSM networks. A transceiver (TRX) can carry one ARFCN which can correspond to the BCCH (7 traffic timeslots) or TCH (8 traffic timeslots). Subcell: A subcell is a group of TRXs with the same radio characteristics. A subcell is fully defined by the "transmitter‐ TRX type" pair. Base station: This is the generic name for a cell site ("site‐transmitter‐cell" or "site‐transmitter‐subcells"). Technology‐ specific names can be BTS, Node‐B, eNode‐B, etc. RF repeater: An RF repeater receives, amplifies, and retransmits RF carriers both in downlink and uplink. The repeater receives signals from a donor transmitter which it retransmits using a coverage‐side antenna with amplification. Remote antenna: Transmitter antennas located at a remote location with respect to the transmitter’s site. Microwave link: A point‐to‐point link using microwave frequencies used for backhaul in radio access networks or for fixed wireless access. PMP microwave link: A group of microwave links originating from a common node to serve more than one location. Passive microwave repeater: A passive microwave repeater receives and retransmits microwave signals without amplification. Passive repeaters do not have power sources of their own. Active repeaters, on the other hand, amplify the received signal. Reflectors are examples of passive repeaters.
9.1 XML Import/Export Format All the data tables in an Atoll document can be exported to XML files. Atoll creates the following files when data tables are exported to XML files: • •
An index.xml file which contains the mapping between the data tables in Atoll and the XML file created for each table. One XML file per data table which contains the data table format (schema) and the data.
When XML files are imported to a document, the table and field definitions are not modified, i.e., the Networks and CustomFields tables are exported to XML file but are not imported. The following sections describe the structures of the XML files created at export.
9.1.1 Index.xml File Format The index.xml file stores the system (GSM, UMTS, etc.) and the technology (TDMA, CDMA, etc.) of the document, and the version of Atoll used for exporting the data tables to XML files. It also contains the mapping between the data tables in the Atoll document and the XML file corresponding to each data table. The root tag of the index.xml file contains the following attributes: Attribute
Description
Atoll_File_System
Corresponds to the SYSTEM_ field of the Networks table of the exported document
Atoll_File_Technology
Corresponds to the TECHNOLOGY field of the Networks table of the exported document
Atoll_File_Version
Corresponds to the Atoll version
The index file also contains the mapping between the tables exported from Atoll and the XML files corresponding to each table. This list is sorted in the order in which tables must be imported in Atoll. The list is composed of tags with the following attributes: Attribute
Description
XML_File
Corresponds to the exported XML file name (e.g., "Sites.xml")
Atoll_Table
Corresponds to the exported Atoll table name (e.g., "Sites")
A sample extract of the index.xml is given below:

Atoll 3.2.1 Administrator Manual Chapter 9: Radio Data Formats
© Forsk 2014
... Note that no closing tag is required.
9.1.2 XML File Format Atoll creates an XML file per exported data table. This XML file has two sections, one for storing the description of the table structure, and the second for the data itself. The XML file uses the standard XML rowset schema (schema included in the XML file between and tags). Rowset Schema The XML root tag for XML files using the rowset schema is the following: The schema definition follows the root tag and is enclosed between the following tags: and tags -> In the rowset schema, after the schema description, the data are enclosed between and . Between these tags, each record is handled by a tag having its attributes set to the record field values since in the rowset schema, values are handled by attributes. Note that no closing tag is required. A sample extract of a Sites.xml file containing the Sites table with only one site is given below:

9.2 RF 2D Antenna Pattern Format This section describes the format of the DIAGRAM field of the Antennas table. This field stores the antenna diagrams in a 2D (angle vs. attenuation) format. This is the format of the contents of the DIAGRAM field of the Antennas table when it is copied from, pasted to, imported to (from TXT or CSV files), and exported from (from TXT, CSV, or XLS files) the Antennas table. Antenna patterns can also be imported in Planet 2D‐format antenna files and 3D antenna files. The file format required for 3D antenna file import is described in "Import Format of 3D Antenna Pattern Text Files" on page 91. The format of 2D antenna patterns containing co‐polar diagrams only can be understood from Figure 9.1 on page 89. Pattern Discriptor 1

You can use a 3rd party software or develop a tool to convert the contents of the DIAGRAM field into binary. In binary, each antenna is described by a header and a list of value pairs. The header is defined as follows: • • • • • • •
flag: (Integer, 32 bits) ‐1 for omni diagrams, 0 for directional num: (Short integer, 16 bits) Number of diagrams (0, 1, 2, 3, 4) siz0: (Short integer, 16 bits) Size of the first diagram (horizontal co‐polar section, elevation = 0°) siz1: (Short integer, 16 bits) Size of the second diagram (vertical co‐polar section, azimuth = 0°) siz2: (Short integer, 16 bits) Size of the third diagram (horizontal cross‐polar) siz3: (Short integer, 16 bits) Size of the fourth diagram (vertical cross‐polar) prec: (Short integer, 16 bits) Precision of the following angle values (100)
Then follows the content of each of the defined diagrams, i.e., the diagrams whose sizes (siz0, siz1, siz2, siz3) are not zero. Each diagram consists of a list of value pairs. The number of value pairs in a list depends on the value of the siz0, siz1, siz2, and siz3 parameters. For example, siz2 = 5 means there are five value pairs in the third diagram. The value pairs in each list are: • •
ang: (Short integer, 16 bits) The first component of the value pair is the angle in degrees multiplied by 100. For example, 577 means 5.77 degrees. loss: (Short integer, 16 bits) The second component of the value pair is the loss in dB for the given angle ang.
All the lists of value pairs are concatenated without a separator.

9.3 Import Format of 3D Antenna Pattern Text Files Text files containing 3D antenna patterns that can be imported in Atoll must have the following format: • •
Header: The text file can contain a header with additional information. When you import the antenna pattern you can indicate the row number in the file where the header ends and the antenna pattern begins. Antenna Pattern: Each row contains three values to describe the 3D antenna pattern. The columns containing the values can be in any order: • Azimuth: Allowed range of values is from 0° to 360°. The smallest increment allowed is 1°. • Tilt: Allowed range of values is from ‐90° to 90° or from 0° to 180°. The smallest increment allowed is 1°. • Attenuation: The attenuation in dB.
9.4 Microwave 2D Antenna Pattern Format This section describes the format of the PATTERN field of the MW Antennas table. This field stores the antenna diagrams in a 2D (angle vs. attenuation) format. This is the format of the contents of the PATTERN field of the MW Antennas table when it is copied from, pasted to, imported to (from TXT or CSV files), and exported from (from TXT, CSV, or XLS files) the MW Antennas table.

9.5 Path Loss Matrix File Format When path loss matrices are stored externally, i.e., outside the ATL file, the path loss matrices folder contains a ‘pathloss.dbf’ file containing the calculation parameters of the transmitters and one LOS (path loss results) file per calculated transmitter. The path loss matrices folder also contains a LowRes folder with another pathloss.dbf file and one LOS (path loss results) file per transmitter that has an extended path loss matrix. The formats of the pathloss.dbf and LOS files are described here.
9.5.1 Pathloss.dbf File Format The pathloss.dbf file has a standard DBF (dBase III) format. The file can be opened in Microsoft Access, but it should not be modified without consulting the Forsk customer support. For general information, the format of DBF files in any Xbase language is as follows: Notations used in the following tables: FS = FlagShip; D3 = dBaseIII+; Fb = FoxBase; D4 = dBaseIV; Fp = FoxPro; D5 = dBaseV; CL = Clipper

In order to benefit from the calculation sharing feature, users must retrieve the propagation models from the same central database. This can be done using the Open from database command for a new document or the Refresh command for an existing one. Otherwise, Atoll generates different model_ID (even if same parameters are applied on the same kind of model) and calculation sharing become unavailable due to inconsistency. These coordinates enable Atoll to determine the area of calculation for each transmitter. These coordinates enable Atoll to determine the rectangle including the computation zone.

9.5.3 LOS File Format The LOS (path loss results) files are binary files with a standard row‐column structure. Data are stored starting from the southwest to the northeast corner of the area. The file contains 16‐bit signed integer values in the range [‐32768; +32767] with a 1/16 dB precision. "No data" values are represented by +32767.
9.6 Path Loss Tuning File Format Atoll can tune path losses calculated by propagation models using CW measurements or drive test Data. Path losses are tuned by merging measurement data with propagation results on pixels corresponding to the measurement points and the pixels in the vicinity. Path losses surrounding the measurement points are smoothed for homogeneity. Measuremment paths that are used for path loss tuning are stored as a catalogue in a folder containing a pathloss.dbf file and one PTS (path loss tuning) file per transmitter. A tuning file can contain several measurement paths. For more information on the path loss tuning algorithm, see the Technical Reference Guide.

9.7 Interference Matrix File Formats Interference matrices are used by GSM, LTE, and WiMAX AFPs (automatic frequency planning tools). Interference matrices can be imported and exported using the following formats: • •
GSM: CLC, IM0, IM1, IM2 LTE and WiMAX: IM2, TXT, CSV
Interference matrix files must contain interference probability values between 0 and 1, and not in precentage (between 0 and 100%). When interference matrix files are imported, Atoll does not check their validity and imports interference probability values for loaded transmitters only. In the following format descriptions and samples, lines starting with the "#" are considered as comments.
In GSM interference matrices: •
• •
The interferer TRX type is not specified and is always considered to be BCCH. Subcells have different powers defined as offsets with respect to the BCCH. For subcells other than the BCCH, if the power offset of a subcell is X dB, then its interference histogram will be shifted by X dB with respect to the BCCH interference histogram. If no power offset is defined on the interfered TRX type, it is possible to set "All". For each interfered subcell‐interferer subcell pair, Atoll saves probabilities for several C/I values (6 to 24 values), including five fixed ones: –9, 1, 8, 14, and 22 dB. Between two fixed C/I value, there can be up to three additional values (this number depends on the probability variation between the fixed values). The C/I values have 0.5 dB accuracy and probability values are calculated and stored with an accuracy of 0.002 for probabilities between 1 and 0.05, and with an accuracy of 0.0001 for probabilities lower than 0.05.
9.7.1 CLC Format (One Value per Line) The CLC format uses wo ASCII text files: a CLC file and a DCT file. Interference matrices are imported by selecting the CLC file to import. Atoll looks for the associated DCT file in the same directory and uses it to decode transmitter identifiers. If no DCT file is available, Atoll assumes that the transmitter identifiers are the transmitter names, and the columns 1 and 2 of the CLC file must contain the names of the interfered and interfering transmitters instead of their identification numbers.
9.7.1.1 CLC File Format The CLC file consists of two parts. The first part is a header used for format identification. It must start with and contain the following lines: # Calculation Results Data File. # Version 1.1, Tab separated format. Commented lines start with #. The second part details interference histogram of each interfered subcell‐interfering subcell pair. The lines after the header are considered as comments if they start with "#". If not, they must have the following format: The 5 tab‐separated columns are defined in the table below: Column
Name
Description
Column1
Interfered transmitter
Identification number of the interfered transmitter. If the column is empty, its value is identical to the one of the line above.
Column2
Interfering transmitter
Identification number of the interferer transmitter. If the column is null, its value is identical to the one of the line above.
Column3
Interfered TRX type
Interfered subcell. If the column is null, its value is identical to the one of the line above. In order to save storage, all subcells with no power offset are not duplicated (e.g. BCCH, TCH).

9.8 "Per Transmitter" Prediction File Format When a coverage prediction is calculated by value intervals it is stored externally, i.e., outside the ATL file. A corresponding ’\{}’ folder is actually created where the ATL document is located, as soon as the latter is saved.
102
Atoll 3.2.1 Administrator Manual Chapter 9: Radio Data Formats
AT321_AM_E1
The calculation of the coverage prediction is either global or "per transmitter". •
When the calculation is global, the results are stored in two files for the entire prediction: one HDR file and one BIL file (both identified by the prediction name).
•
When a calculation is "per transmitter", one HDR file and one BIL file are created for each transmitter in the prediction (both identified by the transmitter’s name). In some "per transmitter" predictions, an additional DBF file is created for the entire prediction (identified by the prediction name). The DBF file contains information on each transmitter and a pointer to each transmitter’s specific HDR and BIL files. In LTE, when a Cell Identifier Collision Zones (DL) prediction is calculated by value intervals with the display type set "No. of interferers per cell", the HDR file and the BIL file are created for each cell in the prediction (both identified by the cell’s name). The format and the content of the DBF file is described here. In both cases, an XML file describing the prediction is also created in the corresponding ’\{}’ folder.
9.8.1 .dbf File Format The format of ‘.dbf’ files is identical to the format described in "Pathloss.dbf File Format" on page 92.

Atoll 3.2.1 Administrator Manual Chapter 10: Administration and Usage Recommendations
AT321_AM_E1
10 Administration and Usage Recommendations This chapter lists various technical recommendations for optimising your work with Atoll.
10.1 Geographic Data Location of the Geographic Data • • •
In multi‐user environments, it is recommended to place all the geographic data on a file server accessible to all the users. This approach avoids the need to replicate the geographic data on all the workstations. Geographic data should either be located on each server or accessible through a fast network connection, e.g., 1 Gbps. You can restrict access to the geographic data locations by assigning read/write access rights to administrators and read‐only rights to end‐users.
Link or Embed • •
Only embed geographic data in ATL files if you wish to make a portable document. In all other cases, it is recommended to link geographic data files to the Atoll documents. It is recommended to set the paths to linked geographic data files using the Universal Naming Convention (UNC). Following the UNC, an absolute path, such as "C:\Program Files\Forsk\Geo Data\...", is represented as "\\Computer\C\Program Files\Forsk\Geo Data\...", where "Computer" is the computer name, and "C" is the share name of disk C. Example: Absolute Path
C:\Program Files\Forsk\Geo Data\...
Relative Path
\Program Files\Forsk\Geo Data\...
UNC Path
\\Computer\C\Program Files\Forsk\Geo Data\...
If you define paths to geographic data files using the UNC, Atoll will be able to keep track of the linked files even if the Atoll document is moved to another computer. Size of Tiles •
•
Some network planning tools require geographic data to be available in small tiles in order to work more efficiently. For a country‐wide project, this can lead to hundreds of files describing the geographic data. Atoll is designed to optimise memory consumption, which enables it to perform efficiently with regional tiles (1 tile/file per region). In Atoll, Merging small tiles to build a regional tile can improve performance greatly. To note as well: • • •
Recommended file size: 100 to 200 MB Erdas Imagine Pyramids files can be bigger. ECW files can be of any size (no limitations).
Recommended Formats •
In order to improve performance, it is recommended to use uncompressed DTM and clutter files, for example, BIL files. Using compressed geographic data files, for example, compressed TIF or Erdas Imagine, can cause performance reduction due to decompression of these files in real time. If you are using compressed geographic data files, it is strongly recommended to: • •
•
Either, hide the status bar that displays geographic data information in real time. You can hide the status bar from the View menu. Or, disable the display of some of the information contained in the status bar, such as altitude, clutter class, and clutter height using an option in the Atoll.ini file, see "Hiding Information Displayed in the Status Bar" on page 160.

10.2 Path Loss Matrices Shared Path Loss Matrices •
•
Shared path loss matrices should be accessible through a fast network connection, e.g., 1 Gbps. These results are accessed by Atoll during calculations, and should be available to the users through a fast network connection, i.e., 30 Mbps at least per user. You can restrict access to the shared path loss matrices folder by assigning read/write access rights to administrators and read‐only rights to end‐users.
Private Path Loss Matrices •
Atoll synchronises the private path loss matrices with the shared path loss matrices. If private path loss matrices are invalid, and the corresponding shared path loss matrices are valid, Atoll deletes the invalid private path loss matrices and uses the shared ones. You can make Atoll verify and remove private path loss matrices, valid or invalid, whose corresponding shared path loss matrices are valid. This can be useful for disk space management. For more information, see "Synchronising Private and Shared Path Loss Matrices" on page 155.
Link or Embed •
Only embed path loss matrices in ATL files if you wish to make a portable document. In all other cases, it is recommended to link path loss matrices to the Atoll documents. Externalising path loss matrices to shared or private path loss folders will keep the ATL file size reasonable, which will result in less fragmentation. Externalising path loss matrices does not reduce the performance of display and calculations in Atoll.
•
It is recommended to set the paths to the private and shared path loss matrices folders using the Universal Naming Convention (UNC). Following the UNC, an absolute path, such as "C:\Program Files\Forsk\PathLosses\...", is represented as "\\Computer\C\Program Files\Forsk\PathLosses\...", where "Computer" is the computer name, and "C" is the share name of disk C. Example: Absolute Path
C:\Program Files\Forsk\PathLosses\...
Relative Path
\Program Files\Forsk\PathLosses\...
UNC Path
\\Computer\C\Program Files\Forsk\PathLosses\...
If you define paths to the private and shared path loss matrices folders using the UNC, Atoll will be able to keep track of the linked files even if the Atoll document is moved to another computer. Calculating Path Loss Matrices in Multi‐RAT Documents •
When the path loss matrices in multi‐RAT documents using the RunPathloss API function, the path loss matrices of each technology are calculated simultaneously using the same number of threads. For example, if 4 threads are used to calculate path loss matrices, and there are 3 technologies (GSM, UMTS, and LTE), a total of 12 threads will be used to calculate the path loss matrices at the same time. This can lead to the following problems: • • •
•
Insufficient CPU resources Insufficient memory Insufficient licences if external propagation models are used.
To avoid these problems when using the RunPathloss API function to calculate path loss matrices in multi‐RAT documents, use the following work‐arounds: • • •
Use the Distributed Calculation Server, even locally. In your script or macro, deactivate the transmitters of the technologies for which you do not want to calculate the path loss matrices and reactivate them afterwards. Repeat it for all technologies. Lower the number of threads using the NumberOfThreadsPathloss option in RemoteCalculation section in Atoll.ini. For example, you can set the option to 2 to use a maximum of 6 threads (3*2) during path loss calculation using the RunPathloss function. •
106
Resource saturation during the calculation of path loss matrices for multi‐RAT documents only occurs when using the RunPathloss API function in a macro or script. When calculating path loss matrices for a multi‐RAT document using Atoll, this does not occur.
Atoll 3.2.1 Administrator Manual Chapter 10: Administration and Usage Recommendations
AT321_AM_E1
•
Atoll synchronises the private path loss matrices with the shared path loss matrices. If private path loss matrices are invalid, and the corresponding shared path loss matrices are valid, Atoll deletes the invalid private path loss matrices and uses the shared ones. You can make Atoll verify and remove private path loss matrices, valid or invalid, whose corresponding shared path loss matrices are valid. This can be useful for disk space management. For more information, see "Synchronising Private and Shared Path Loss Matrices" on page 155.
10.3 Atoll Documents General • •
It is recommended to define a rule for making backups of your Atoll documents at regular intervals. Do not skip a major Atoll version. For example, if you are currently using Atoll 2.8.x, you should first upgrade the document to Atoll 3.1.x before upgrading to Atoll 3.2.x. Upgrading your document will be simpler if you do not skip a major version. If you skip or have skipped an intermediate major version, you should upgrade your document twice in order to make it compatible with the new version.
10.4 Databases General • • • •
In order to use Atoll with Oracle, you must create Oracle users and schema with names in uppercase. Create backups of the database before upgrading. It is recommended to define a rule for making backups of the database at regular intervals. Do not skip a major Atoll version. For example, if you are currently using Atoll 2.7.x, you should first upgrade the database to Atoll 2.8.x before upgrading to Atoll 3.1.x. Upgrading your database will be simpler if you do not skip a major version. If you skip or have skipped an intermediate major version, you must upgrade your database twice in order to make it compatible with the new version.
Tables and Fields • •
Table and field names are case sensitive. Table and field names should be not more than 20 characters long. Oracle databases allow a maximum length of 30 characters for field and table names. However, for use in Atoll, you must not create tables and fields with names longer than 20 characters. This is because Atoll adds some characters to the table and field names for certain operations: creating associated triggers, creating project databases, etc. Limiting the length of table and field names to 20 characters will help avoid database connection and consistency problems.
• • • • • •
• •
Table and field names should only use alphanumeric characters (A‐Z, a‐z, 0‐9) and underscores (_). Table and field names must not start with a numeric character (0‐9). Table and field names must not contain an SQL or RDBMS‐specific keyword, such as ORDER, DATE, etc. Table and field names must not contain spaces or special characters, such as periods (.), exclamation marks (!), colons (:), semi‐colons (;), interrogation marks (?), parentheses (()), brackets ({}), square brackets ([]), etc. Boolean fields, system or user‐defined, should always have default values assigned. The CustomFields table enables you to define default values, choice lists, and read/write access for any field in any table in Atoll, including user‐defined fields that you add to the Atoll tables. The values defined in this table have priority over the internal predefined default values. If you define floating point default values, make sure that all the users have the same decimal separator. If you wish to add custom fields in the Atoll document, you should first add the field in the database, and then update your Atoll document from the database. When setting up your database for the first time, try to anticipate user requirements in terms of custom fields in Atoll tables. Some requirements of the different user groups can be satisfied if a few general‐purpose user‐defined fields are added in Atoll tables when setting up the database. For example, if you add three user‐defined fields (one of type integer, float, and text (limited size)) to the Sites and Transmitters tables, users will be able to use these for sorting, filtering, grouping, or other purposes. This approach can help the database function a long time before users require the addition of other custom fields.
• •
•
To improve performance, if your projects allow it, reduce the size of the fields corresponding to the sites and transmitters’ names. To improve performance, unless absolutely necessary, do not add user‐defined fields of Text type. Rather, use numeric field types, which allow sorting and other functions. If you must add Text fields, allocate them the appropriate size that would suffice. For example, a 255‐character long Text type field would, for the most part, occupy disk space for no purpose. To improve performance, you should avoid adding custom fields to the neighbour management tables.

10.5 Calculation Server Computation Server Stability and Resource Management In certain conditions, as described below, Atoll users might experience a decrease in server performance and stability in a multi‐user Citrix environment. The principal difference observed might be the inability to run multiple Atoll sessions on the server without getting error messages, general application failures, or server crashes. Such problems can occur when the number of Atoll sessions on the server, carrying out calculations, increases to more than four. Causes of Instability and Loss of Performance This general instability and low performance of the servers is due to: • • •
Insufficient memory resources: globally and per process (Atoll session) Insufficient CPU resources Network congestion
Atoll can process four simultaneous path loss matrices calculations, which means high CPU and RAM resource consumption, and as path loss calculations share the amount of memory allocated to the Atoll session, the total memory requirement can exceed the Microsoft Windows’ (32‐bit editions) limit of 2 GB per process. This is especially the case with large Atoll documents and propagation models that require considerable memory. Troubleshooting and Solution As the cause of this problem is resource saturation on the server, resource consumption should be controlled in order to avoid memory and CPU overloading as follows: •
To reduce the impact of a large number of simultaneous path loss calculations, a Distributed Calculation Server should be set up. Using the Distributed Calculation Server, path loss calculations can be performed outside Atoll. Using the Distribution Calculation Server has the following advantages: • Path loss calculations are limited to four parallel instances regardless of the number of Atoll sessions running on the server. This notably improves the memory and CPU consumption. • A queuing system, integrated in the Distributed Calculation Server, manages the calculation requests from different Atoll sessions. • A failover mechanism automatically switches and hands over the path loss calculations back to Atoll in case a problem occurs. • Path loss calculations are carried out by a separate process (AtollSvr), which has its own memory allocation apart from Atoll, i.e., the amount of memory needed for calculations does not impacts the Atoll memory allocation.
This set up can introduce considerable improvements in both the number of Atoll sessions per server and the calculations. A server with four processors (eight threads with hyper‐threading) can accommodate four simultaneous path loss calculations and use the other four threads for Atoll sessions. Atoll’s interface will also be more efficient and the overall processing time for various tasks will be improved. In order to prevent users from deactivating the use of the Distributed Calculation Server, and hence bypassing the resource control procedure established above, the Atoll.ini file should be set made read‐only for end‐users. Apart from the above setup, you can also make some other system improvements: •
To avoid error messages caused by requesting a large number of files over the network, the following Microsoft Windows registry parameter can be modified in order to dedicate more resources to network read/write operations: IRQSTACKSIZE should be set to 30 instead of 11, for example.
•
•
To avoid ‘out of memory’ problems, the Pagefile size should be increased so that the server does not run out of global memory when supporting more than 10 Atoll sessions simultaneously. This is different from the 2 GB per process limit. Virtual memory can be increased from 8 GB to 16 GB, for example. For 32‐bit Windows operating systems, you can also increase the default Windows memory allocation limit from 2 GB to 3 GB as explained in "Process Memory" on page 109.
10.6 Atoll Administration Files There is no specific order in which configuration and initialisation files should be created or installed on Atoll workstations and servers. It is sufficient to have these files created and placed in the right locations before running Atoll to have the predefined configuration of all workstations and servers. If you have already configured these files for one server, and you are setting up another server, you can copy these files to their respective locations on the new server to have the exact configuration and set‐up as the first. If you do not copy these
108
Atoll 3.2.1 Administrator Manual Chapter 10: Administration and Usage Recommendations
AT321_AM_E1
files, or create them, you will not have the same configuration of the new server, but apart from that you will be able to work with Atoll normally. These files are optional, not obligatory. Initialisation File (INI) • •
It is highly recommended that the Atoll initialisation file be created and modified only by the administrator. If you are using Windows 2000 Server, state the actual number of processors in the INI file.
User Configuration File (CFG) • • •
Use Atoll to create these files and avoid modifying these files manually as human errors can create problems. Uncheck image visibility to avoid loading unnecessary data in the memory. You can set up your configuration files in the following manner: • •
•
A common configuration file that points to the geographic data, macros, and other common parameters in your Atoll documents. Separate configuration files created for your 2G and 3G projects, which would store their respective coverage prediction studies parameters, traffic information, neighbour allocation parameters, and other technology‐ specific parameters. Separate configuration files based on, and for, different groups of users. These groups of users can be, for example, groups of users working on different regions, groups of users working on different technologies, groups of users focusing on certain operations (i.e., performing certain types of coverage predictions, performing the AFP, etc.).
Custom Predictions File •
Coverage prediction studies can easily be duplicated within Atoll. Before creating study templates, and the XML studies file, make sure that this study template is aimed at serving a number of users. This means, avoid creating study templates unless these will be needed for a long time by a number of users. You can use the configuration files to store your created coverage prediction studies locally. And, you can also use the study duplicate feature to create copies of existing coverage prediction studies.
10.7 Process Memory 32‐bit Operating Systems Atoll can support 3 GB address space on a properly configured 32‐bit system. For more information, please refer to the following URL: http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx (/3GB section in “Memory Support and Windows Operating Systems”). The following link provides information on how you can setup your Windows Server 2003 systems to activate the 3 GB switch at startup: http://technet.microsoft.com/en‐us/library/bb124810.aspx. 64‐Bit Operating Systems The 64‐bit editions of Microsoft Windows provide 4 GB of memory per process.
10.8 Printing You should place different layers of geographic and radio data in a definite order when printing a project or a section of the project. The following order should be followed: 1. Visible objects of the Data tab All the visible objects of the Data tab are displayed above those in the Geo tab. However, it is strongly recommended to place vector layers on the top of coverage prediction plots. You can do this by transferring these vector layers to the Data tab using the context menu. For performance reasons, it is advised to place vector layers on top of raster layers before printing a project. Sites and Transmitters must be on the very top, above all other layers. You should place sites and sectors on the top, then vector layers, and then raster layers. 2. Unidimensional vectors (points) 3. Open polygonal vectors (lines, i.e., roads and other linear items, etc.) 4. Closed polygonal vectors (surfaces, i.e., zones and areas, etc.) 5. Multi‐format maps (vector or raster maps, i.e., population, rain, generic maps, traffic, etc.) 6. Transparent raster maps (clutter class maps, etc.) 7. Non‐transparent maps (images, DTM, clutter height maps, etc.)

10.9 Coverage Prediction Calculations •
•
If you do not want Atoll to calculate the shadowing margin during a coverage prediction, it is advised to clear the Shadowing taken into account check box. This approach is more efficient in terms of performance than selecting this option and setting the Cell edge coverage probability to 50%. To improve memory consumption and optimise the calculation times, you should set the display resolutions of coverage predictions according to the precision required. The following table lists the levels of precision that are usually sufficient: Size of the coverage prediction
Display resolution
City Center
5 m
City
20 m
County
50 m
State

Country
According to the size
10.10 CW Measurements and Drive Test Data •
•
It is recommended to use Fast Display in order to increase display speed. This option is available in the Display tab of the Properties dialogues for CW Measurements and Drive Test Data folders. Although this approach only displays measurement points as small squares, it can have a significant impact on performance depending on the number of measurement points in the Atoll document. When performing a CW measurements drive test campaign, please follow the recommended procedure described in the Measurements and Model Calibration Guide.
10.11 Antenna Patterns and Import •
•
•
Antenna names used in some tools, such as NetAct, can be different from those used in their corresponding antenna files. To solve this issue, you can create a new file, named "Index", containing the list of antenna names, which would in fact be the pattern (antenna file) names. You should place this file at the same location as the antenna patterns (files). This will replace the antenna names with the new antenna names. Some Kathrein antenna pattern files might have names different from the antenna pattern names present inside the file. You will have to replace the name of the pattern inside the file by the name of the pattern file itself, in order to import these antennas correctly. A Planet Index file contains the path to and the name of each antenna file available. Creating such an Index file when there are hundreds of antenna patterns available can be a difficult task. You can easily create the index file from the Microsoft Windows command prompt. You can open the Command Prompt window by selecting Start > Run, entering "cmd" and pressing ENTER. In the Command Prompt window, navigate to the directory containing the antenna pattern files, enter the following command and press ENTER: dir /b > Index This will create a file called "Index" in the same directory as the antenna patter files containing a list of all the antenna pattern file names, with one name per line. The file will also contain a line with its own name, so, before importing this file into Atoll, you should use a text editor to remove the line containing the file name "Index."
•
The electrical tilt, which can be defined in the antenna properties dialogues in Atoll, is an additional electrical downtilt. It might be redundant to define an additional electrical downtilt for antennas whose patterns already include electrical tilt. Users should verify whether the antenna patterns of the antennas in their projects, do not already include the effect of an electrical tilt.
10.12 Traffic Maps • • •
110
User profile environment‐based traffic maps should only be used for a precision on traffic that is of the same level as the statistical clutter available in a project. For higher precision on traffic data, you should use sector traffic maps or user density traffic maps. User density traffic maps provide you with a means to define a density for each set of service, terminal type, and mobility type. Sector traffic maps are best suited for traffic data issued by the OMC.
Atoll 3.2.1 Administrator Manual Chapter 10: Administration and Usage Recommendations
AT321_AM_E1
10.13 Atoll API Correct functioning of Atoll when using Atoll through the API is guaranteed during interactive user sessions only. Atoll is an application that requires creating tool bars, creating menus, reading user profile options from the Windows’ registry, accessing printers, etc., even when it is accessed through the API. The same is true for add‐ins working with Atoll. Even though it is possible to load and use Atoll when there is no user session open on a computer, its correct functioning is not guaranteed. Unexpected errors can occur. Particularly, creating objects through CreateObject or CoCreateInstance might fail. Therefore, the correct functioning of Atoll requires an open user session on the computer.
10.14 Performance and Memory Memory Refresh •
You can avoid memory fragmentation while working with Atoll documents by saving the Atoll document from time to time, closing and restarting Atoll, and reopening the document. This advice is applicable to any application running under Microsoft Windows because many common DLL files are accessed by applications, and unloading and reloading these DLL files refreshes the memory allocation.
• •
If you are working in a Citrix XenApp environment, you should restart your Citrix server every week or fortnight. The exact time should be determined by the administrator depending on the state of the network (LAN). In certain cases, it might be more appropriate to start working on a completely fresh ATL file. If you have been working on your existing ATL file for a long time, it might become unnecessarily large and might contain some useless remains from your earlier operations, e.g., traces of records that no longer exist in the database, etc. You can completely refresh your project by following these steps: a. Open the existing ATL file in Atoll that you want to replace. b. Create a CFG file from your existing ATL file with all the required information, e.g., geographic data set, coverage prediction parameters, neighbour allocation parameters, etc. For more information, refer to "Configuration Files" on page 117. c. Close the old ATL file. d. Create a new ATL from the database to create a fresh ATL file. e. Import the CFG file in the new ATL file. You now have a clean ATL file to work with, which has all the same information as the old ATL file, and takes up less space on the hard disk, has less fragmented data, and improved performance.
Memory Allocation •
•
If you have to open several large ATL files simultaneously on the same computer, it is better to open each in a separate Atoll session rather than to open them all in the same Atoll window. Each Atoll session on the same computer has its own memory space allocated by the operating system. Each computer consumes a single licence token independent of the number of Atoll sessions opened simultaneously. For 32‐bit Windows operating systems, you can also increase the default Windows memory allocation limit from 2 GB to 3 GB as explained in "Process Memory" on page 109.
File Size •
Coverage predictions calculated over large areas require more memory. If you are working on an Atoll document covering a large area, with coverage predictions calculated over the entire network, this document will require more memory for loading all the coverage predictions. You can reduce memory consumption by making copies of your Atoll document, and keeping a few coverage predictions in each copy. These ATL files will be faster to load and work with compared to a single ATL file with all the coverage predictions. Large coverage predictions can take up a considerable amount of memory even if they are not displayed on the map.
•
Externalise DTM, clutter, path loss matrices, and any other data that can be externalised, so that the ATL file size does not become unnecessarily large.
Path Loss Calculation •
Before starting path loss calculation, verify that the calculation radii and resolutions assigned to the different types of transmitters are consistent. For example, calculating path loss matrices of picocells over large calculation radii would only waste memory and disk space.
111
Atoll 3.2.1 Administrator Manual Chapter 10: Administration and Usage Recommendations
•
© Forsk 2014
For calculating path loss matrices over large areas, you should use the dual resolution feature in Atoll. Define short calculation radii and fine resolutions for the main path loss matrices, and large calculation radii and low resolutions for extended path loss matrices. This approach decreases the calculation time significantly compared to calculating just one matrix per transmitter using a fine resolution. The main path loss matrices should be calculated using the same resolution as the resolution of the geographic data available. The extended path loss matrices can be calculated using a lower resolution, e.g., twice the resolution of the geographic data.
Regionalisation •
Use database regionalisation or site lists if you are working on smaller parts of a large network. Atoll loads only the data necessary for your working area. If you load a large network, Atoll will load a lot of data that might not be necessary all the time, such as the neighbour relation data.
Performance and Memory Issues in Large GSM Projects Memory problems might be experienced in the C/I coverage prediction studies, interference matrices calculations, and the AFP while working on large GSM networks. Large network projects are more susceptible to these problems. If the network is large but homogeneous, these problems might only appear if the number of transmitters is over 15,000 or so. But, if there are large city centres involved, with each pixel having many overlapping path loss matrices, then this size limit might decrease to around 5,000 transmitters or so. Also, if the Atoll session has been open for a long time, memory problems can even appear while working on smaller networks. This is because the process memory space (memory space allocated to Atoll by the operating system) becomes fragmented. Following is a list of advice which you can follow in order to avoid such problems: •
•
•
•
Use regionalisation or site lists: If you load a large network, Atoll will be required to load a lot of data that might not be necessary all of the time. For example, in a typical large GSM network, you might have around 10,000 transmitter records, 20,000 subcell records, 50,000 TRX records, and up to 150,000 neighbour records. Externalise embedded interference matrices: You can store interference matrices listed in the Interference Matrices folder in external files. Atoll loads interference matrices from the external files to the memory only when needed. You will also reduce the ATL file size by externalising the interference matrices. Adapt calculation radii to the cell type and the EIRP: Before calculating path loss matrices, take care to correctly associate calculation radii and resolutions to different types of cells. If you calculate path loss matrices for all types of cells over a large calculation radius, it will unnecessarily burden the C/I and interference matrices computations. Properly configure the interference thresholds: These thresholds indicate the level after which an interferer can be ignored. The default value for this threshold (‐130 dBm), defined in the Predictions tab of the Predictions folder’s Properties dialogue, means that the computations will take into account all the interferers. However, if you set it too high, you might lose important interference information. The proper value for this threshold depends on the Reception Thresholds and the C/I Thresholds defined in the Subcells table. The optimum value would be Min AllSubcells RT i – CIT i – M . Which means the minimum value of the factor RT i – CIT i – M computed for all subcells, i. Where, RTi is the reception threshold of the subcell i, CITi the C/I threshold of this subcell, and M is a safety margin. Since this interference threshold is used both in interference matrices calculation and in interference predictions, it is important to have at least a 3‐dB margin for the interference energy aggregation in C/I studies. We recommend a safety margin of 5 dB, which can be reduced if any problem is encountered.
•
•
•
Do not define very high C/I quality thresholds (Default values: 12 dB for BCCH and 9 dB for TCH). If you want a certain TRX type to carry GPRS/EDGE traffic, you can add 1 or 2 dB to this value for that TRX type, and use the option of safety margin in the AFP module’s Cost tab. The 12 dB and 9 dB default values already include safety margins. If you increment these values too much, it will unnecessarily load the interference matrix generation and the AFP. Do not start an AFP session if the interference matrices report indicates problems: All the transmitters should have interferers and very few of them (not more than 20%) should have more than 70 interferers. If there are too many or too few entries in your interference matrices, the AFP plan will not be optimal. If the memory‐critical task is interference matrices generation: You can generate interference matrices in a piecewise manner. This means that you can generate nation‐wide interference matrices with low resolutions based on the percentage of interfered area (to improve computation time), with a cell edge coverage probability of 50% (which means no access to clutter for reading standard deviation values), and an interference threshold of ‐112 dBm. This will provide rough global interference matrices which can be locally improved. These interference matrices will be less memory‐ consuming. Then, use polygon or site list filters to focus on each important location, and calculate local interference matrices with higher resolutions and reliabilities. Make sure that the computation zone in your project completely encompasses the filtering zones that you define.
•
112
If the memory‐critical task is the AFP session: Try to make the document lighter, e.g., remove coverage prediction studies, exit and restart Atoll, and try to generate interference matrices with fewer entries.
Atoll 3.2.1 Administrator Manual Chapter 10: Administration and Usage Recommendations
AT321_AM_E1
•
If the memory‐critical task is the traffic capture: You can use traffic load field of the Subcells table to provide traffic loads directly to the AFP, and possibly skip this step.
Performance and Memory Issues in UMTS/CDMA Simulations •
In order to optimise memory usage during simulations, you can set the "Information to retain" option to "Only the Average Simulation and Statistics". With this option Atoll uses much less memory because it only keeps limited information in memory during the simulation process. Simulation results are detailed enough to be used in generating coverage prediction studies.
Performance and Memory Issues in Co‐planning Projects Co‐planning with Atoll requires that both technology documents be open in the same Atoll window at the same time. However, loading, for example, a GSM and a UMTS document can cause memory saturation especially if the documents contain large, country‐wide networks. To decrease the amount of memory used by Atoll in such cases, you can: • •
Load vector layers in main document only. Loading vectors in the linked document is not necessary and only consumes more memory. Avoid loading neighbours and custom fields which are not required. This can be performed by creating views in the database. For more information, see "Appendix 2: Setting Up Databases for Co‐planning" on page 60.
10.15 Appendix: Memory Requirements This part gives some aspects of memory requirements (both RAM and hard disk space) for Atoll depending on the network to be planned. Atoll is capable of performing computations in pixel sizes different from those of the raster maps in a project. It is recommended to perform detailed planning with smaller pixel sizes in high density areas, and country‐wide (or region‐wide, depending on the size) coverage predictions and other calculations using larger pixel sizes. This approach will provide overall satisfactory results, and will considerably improve the disk space requirements, RAM allocation and calculation time. Please note that the figures mentioned in the following sections are approximate, and though actual figures can vary, their deviation from the approximate values will be negligible. These approximate values are computed through simplified formulas. These formulas do not consider all the input parameters, but only the input parameters that have a considerable impact on memory requirements.
10.15.1 Disk Space Requirements The amount of disk space required for data varies from project to project. It depends mainly on the size of the planning area, the pixel size, and the number of cells. In networks with only a few cells, the amount of disk space required is chiefly determined by the size of the planning area. In networks with a large number of sites, transmitters and cells, it is the number of these network entities that governs this requirement. Pixel size plays an equally important role in all cases. Network‐Wide Input The file sizes for raster maps (DTM, clutter heights, clutter classes, traffic density or environments, images, etc.) does not depend on the number of cells, but only on the size of the planning area in pixels. The following information can provide you with an estimate of disk usage for different geographic data: • • • • •
Clutter class maps require 1 byte per pixel (2 bytes for Planet format). Background images require from 1 to 3 bytes per pixel. Traffic maps require 1 byte per pixel (2 bytes for Planet format). DTM or clutter height maps require 2 bytes per pixel. Population maps or other generic maps require from 1 to 4 bytes per pixel.
For one clutter map, one DTM map, one traffic map, and one background image, you can estimate 6 bytes per pixel of the input area. This data can be shared between different planning alternatives of the same network. If an embedded geographic data file is deleted from the project, Atoll automatically compresses the ATL file to avoid file fragmentation.
Cell‐Specific Results For a project with a large number of cells, it is important to consider the disk space required by the propagation prediction results of each cell. Here, the cell calculation area and the calculation resolution are important factors.
113
Atoll 3.2.1 Administrator Manual Chapter 10: Administration and Usage Recommendations
© Forsk 2014
Cell‐specific results require 2 bytes per pixel. For example, the propagation results for a sector with a calculation area of 1024 x 1024 pixels will require 2 MB disk space. If there are different ATL files for planning the same part of the network in different ways, each ATL file will require the same amount of disk space. The same rule applies to extended path loss matrices as well. If embedded path loss matrices are externalised, Atoll automatically compresses the ATL file to avoid file fragmentation.
Network‐Wide Output Network‐wide output (raster results) mainly depends on: • • • •
The size of the planning area The pixel size The number of coverage predictions The types of coverage predictions
Coverage predictions can have a number of layers depending on the calculation criteria. There can be a single layer for the entire network or a layer per transmitter, sector, or subcell. The resulting size depends on the number of layers and the number of colours and thresholds. Therefore, Atoll coverage predictions can require between 1 bit and 2 bytes per pixel of the calculation area.
• •
Atoll can compress the coverage prediction results when saving a ATL file to avoid file fragmentation. You can consider 14 bytes per pixel as a rough estimate to determine the disk space required for each individual ATL file.
Temporary Disk Space Atoll requires some disk space to temporarily store intermediate results during calculations. A file is created in the system’s temporary directory whose size depends on the calculations. This file is described in the section on RAM requirements. Likewise, a temporary file is created when using the "Save As" command. These files are erased after the calculations or once the storage has finished. Other Disk Space Requirements Other objects in a ATL file that require disk space can easily be neglected in real‐life scenarios since the required disk space depending on the size of the planning area and the number of transmitters is much higher. ATL files store database tables and calculation results. An empty ATL file requires around 500 KB. Each additional site requires between 1 and 2 KB, which is negligible compared to the size of the propagation results. Furthermore, the size of vector files is negligible compared to that of other geographic data, as their size is usually much smaller than the DTM, clutter height, and clutter class maps. When saving an ATL file, Atoll estimates the size of unused spaces in the file due to fragmentation. If the amount of unused spaces is more than half of the useful space, Atoll proposes compressing the file.
10.15.2 RAM Requirements Usually, 512 MB of RAM in a workstation is sufficient for all operations with Atoll, provided that there are no other applications being used in parallel that consume large amounts of memory. Starting Atoll without loading a project requires around 20 MB of RAM (as monitored with the Windows Task Manager). Loading a project with 500 sites, a few predictions, and some simulations can increase the consumed memory to around 50 to 100 MB. Monte Carlo Simulations UMTS Monte‐Carlo simulations are calculations that consume large amounts of memory. The memory requirement of these calculations is a function of the following: •
114
The number of sites involved
Atoll 3.2.1 Administrator Manual Chapter 10: Administration and Usage Recommendations
AT321_AM_E1
• • • • • • • • •
The number of transmitters involved The number of cells involved The number of mobiles generated by the UMTS simulation The number of transmitters covering a pixel The number of services simulated The number of neighbours per cell The "Detailed Results" and "Limit Active Set to Neighbours" flags The number of links per mobile The number of channel elements per site
Most of these parameters have minor influences and the actual requirements are mostly governed by the number of cells and the number of mobiles generated. Assuming that there are three carriers used and the number of transmitters and mobiles is high enough so that the other input can be ignored, the required memory can be roughly approximated by: R = 14.0 t + 3.25 m
for normal simulations
R = 14.0 t + 4.3 m
using the "detailed results" option
with R: peak RAM requirement in KBytes t: number of transmitters affecting the computation zone m: number of mobiles generated by the UMTS simulation Example: To calculate for 500 sites (or 1500 transmitters) and 2400 mobiles, around 28 MB of RAM are required for a normal simulation and 30 MB if detailed results are to be stored as well. • •
•
Please note that this is the peak requirement. Less memory will be required once the calculations are terminated. This approximation also considers effects due to the operating system, such as memory over‐allocation due to fragmentation. It is a conservative approximation and in most cases the actual RAM requirement will be below these calculated figures. A more accurate estimation of the used and required memory for UMTS simulations is available in the Source Traffic tab of the new simulation group dialogue. To activate the memory estimation feature, you must add an option in the Atoll.ini file. For more information, see "Estimating Required and Used Memory Size for UMTS Simulations" on page 172.
Coverage Predictions RAM required during coverage prediction calculations (network‐wide raster result) is the same as the required additional disk space, i.e., between 1 bit and 2 bytes per pixel of the calculation area. Apart from this, temporary memory is required for calculations like "Coverage by transmitter" and "Coverage by signal level". For these, Atoll temporarily allocates an average of 4 bytes more per pixel (8 bytes, if the best server margin is not zero) of the calculation area. Example: The Paris region has a size of around 10 x 13 km. For a calculation resolution of 25 m, this equals 5.2 million pixels. If a coverage prediction calculates the signal strength of the UMTS pilot in less than 16 colours, it would require a memory of 4 bits per pixel, or a total of 2.6 MB. During the calculation, Atoll would also require 4 more bytes per pixel, which equals 20.8 MB more apart from the 2.6 MB. For large networks, to avoid loading the entire computation zone in memory, Atoll divides the coverage prediction computations into smaller tiles, and carries out the computations on them successively. This subdivision is invisible to the user.

11 Configuration Files Configuration files can be used to store parameter and display settings. These files are optional, not required for working with Atoll, but are useful means for making work easier. This chapter describes the formats of these files in detail: •
User configuration files (UTF‐8 encoded XML‐format GEO or CFG files) A user configuration file containing only the geographic data settings can be saved with a GEO extension. A user configuration file containing the geographic data settings and other parameter settings can be saved with a CFG extension. User configuration files must be created using Atoll to ensure correct syntax and structure. It is possible to edit the contents of these files in an XML editor and make changes if required (for example, to update the paths to geographic data files). For more information on how to create and load user configuration files in Atoll, see the User Manual. These files can store: • • • • • • • • • • • •
Geographic data settings Filtering, focus, computation, printing, and geographic export zones Map centre and zoom level Folder configurations List of coverage predictions in the Predictions folder and their settings Automatic neighbour allocation parameters Automatic frequency planning parameters (GSM GPRS EDGE documents) Automatic scrambling code allocation parameters (UMTS HSPA and TD‐SCDMA documents) Automatic PN offset allocation parameters (CDMA2000 documents) Automatic OFDM resource allocation parameters (LTE, WiMAX, Wi‐Fi) Microwave link parameters Full paths to macro files • •
Projection and display coordinate systems are stored in the database, not in user configuration files. Simulation settings are not stored in user configuration files.
For more information on the contents of user configuration files, see "Contents of User Configuration Files" on page 118. A user configuration file can be automatically loaded when Atoll is run if: a. The file is identified in the command line parameter ‐Cfg "cfgfilename" (see "Atoll Command Line Parameters" on page 24 for more information), or b. The file is named "Atoll.cfg" and is located in the Atoll installation folder. This file will be ignored if a user configuration file is loaded through the command line parameter. •
Additional configuration files (UTF‐8 encoded XML‐format CFG files or plain text INI files) The following parameter settings can be stored in additional configuration files with a CFG extension: • • •
Print setup configuration Table import/export configuration Coverage prediction report configuration
The following parameter settings can be stored in specific INI files: • •
CW measurement import configuration Drive test data import configuration
For more information on the contents of additional configuration files, see "Contents of Additional Configuration Files" on page 141. •
Custom predictions file (UTF‐8 encoded XML files) This file (one for all customised predictions) contains the list and parameter settings of customised coverage predictions. By default, this file is named "Studies.xml" and is located in the Atoll installation folder. The custom predictions file must be created using Atoll to ensure correct syntax and structure. It is possible to edit the contents of this file in an XML editor and make changes if required. For more information on working with customised predictions in Atoll, see the User Manual.
