Permitting and Preventing Multiple Users You can configure ARRAYWIZARD to allow more than one administrator to schedule jobs. This is achieved by allowing each administrator to create their own personal user schema in the same database. The default schema can be used by any user whereas a user schema can only be used by b y the user who created it. Any parameter sets that are stored in a user schema will only be visible to the user that created the schema. There can only ever be one default schema but there can be multiple user schemas. Each agent machine can only work with one schema. If you are using two user schemas then you will need at least two agent machines available.


Page 19

To permit multiple users: 1

From the Tools menu, click Allow user schemas so there is a tick next to this option:

If this is the first fi rst time you have done this, a message informing you that you will need to log out and in again for the change to take effect appears. 2

CHAPTER 3

Setting Up Agents ARRAYWIZARD can distribute the processing load across multiple PCs to achieve greater speeds and to accomplish large tasks. In the context of ARRAYWIZARD, "agents" are applications that generate predictions and arrays based on parameter sets. ARRAYWIZARD defines 3 types of agent, namely “Prediction” agents, “2g” agents and “3g” agents, with each one having a connection to the central ENTERPRISE database. A single PC can run multiple instances of such agents. You can choose to run agents on separate machines in your network, for distributed processing. These can predict and re-predict out-of-date sites at defined intervals. Intervals can be set in the scheduler or you can manually start and stop parameter sets. The following table details the associations between agents and parameter sets: This agent

Requires this parameter set

2g

2g Analysis

3g

3g Analysis

Prediction

Prediction

About the th e Agent Status The current status of your agents is indicated in the right hand pane of the ARRAYWIZARD main window under the heading of Status.

ArrayWizard User Reference Guide 7.0 Setting Up Agents

Page 23

The following table shows the status meanings: Status

The agent is stopped and will need to be started (manually or automatically) in order to run tasks. To start an agent manually, see Starting and Stopping Agents on on page 25. page 25.

Idle

The agent is available to run tasks but is not currently processing any.

Not Responding

There is no response from the agent. Check the agent.

Switching Project

The agent has completed a task belonging to one project and is about to process another belonging to a different project.

Working

The agent is in the process of running a task.

Unknown

ARRAYWIZARD Administrator Administrato r has just been started and has not yet received a polling response from the agent.

Responding

The agent is responding to polls but has not provided a status update since the ARRAYWIZARD Administrator was started.

Error

An error has occurred. The agent will not process any more tasks until it has been restarted. To start an agent manually, see Starting and Stopping Agents on on page 25. page 25.

Adding Agents By adding agents, you can choose a type of agent and decide where you want your agent to run from. You will need to have the ARRAYWIZARD Agent software installed on any machine you select. It may be that agents have already been added during the installation process. See Configuring Agents on page 26 page 26 for further details. To add an agent: 1

In the left hand pane of the main window right-click on Agents and from the menu that appears, click Add Agent:

2

You can select your local machine to add or if you have a network, you can distribute the processing of agents to other machines. Distributed processing allows you to share the resources of your network and is helpful if you are running frequent predictions or predictions for large networks. Agents read and write predictions to a common shared directory. In the Agent Name field of the New Agent dialog box that appears: 



Page 24

If you wish to run the agent from your local machine, type in the name of your local machine. If you wish to run the agent from a machine present on your network, type in the name of the networked machine. ArrayWizard User Reference Guide 7.0 Setting Up Agents

Page 28


CHAPTER 4

Creating Arrays Using ARRAYWIZARD Arrays are generated from network information stored in your database. You can configure parameter sets to extract this information from your database and create your arrays. You can schedule the interval for this extraction extracti on to ensure that your predictions and arrays are up to date. If they are found to be out of date, they are updated during the predictions process. Before you create coverage analysis arrays, ensure you have created filters and coverage schemas in ENTERPRISE and ASSET. For more information see the ENTERPRISE and ASSET User Reference Guides.

About Array Creation ARRAYWIZARD uses the same system to create its Pathloss Predictions and Coverage Arrays as ASSET. It can create: GSM Coverage arrays such as Best Server and Service Area (block or contour) 3g arrays such as Pilot Strength, Ec/Io, Pilot Polluters and Handover Type for UMTS and CDMA2000 networks ARRAYWIZARD uses tiling as a way of breaking down the region of interest into more manageable portions which require fewer resources and can also be distributed for processing. By decreasing the tile size, you can create more tiles which require less l ess memory and processing, but consequently decrease the speed of the calculations. The tile size defines the distance in km that each array file is created for. For example, a tile size of 30 will create array tiles of 30 x 30 square km for the entire area of the network you are using for your predictions.

Display sites and filters in your network from which you wish to produce your arrays.

For more information on these steps see the ENTERPRISE User Reference Guide. When you create a parameter set for analysis arrays as described in the following sections, you can apply the current map view to it.

Creating Parameter Sets You can use parameter sets to retrieve specific parameters from your database relating to arrays you wish to generate. By using parameter sets you can choose exactly which data elements you wish to extract from your database in order to create the arrays you require. The three types of parameter set that you can create are: 2g Analysis Parameter Sets 3g Analysis Parameter Sets Prediction Parameter Sets The following sections describe how to create each of these three types of parameter set. For more information on the setting and use of specific parameters see the ENTERPRISE and ASSET User Reference Guides.


Page 31

Creating 2g Analysis Parameter Sets 2g analysis parameter sets are used to retrieve information from your database which is needed to create 2g analysis arrays. For more information on the setting and use of specific parameters see the ENTERPRISE and ASSET User Reference Guides. Before creating 2g analysis parameter sets, ensure that you have added an agent. For information on how to do this, see Adding Agents on page 24. If you have not yet opened a project you must now do so as described under Opening and Closing Projects on page 30. To create 2g analysis parameter sets: 1

In the left hand pane of the Main Window select 2g Analysis.

2

Right-click and from the menu that appears, select Add 2g Analysis:

3

On the Select View page that appears, enter in the co-ordinates for the area of your network view containing the sites you wish to predict. - or – If you are displaying the sites in the Map View window, click Select View to use the view currently displayed.

4

Click Next.

5

Select the filters you wish to use and click Next.

6

Select the types of arrays you wish to create. If you wish to display a particular Nth best server, type a value for N next to the checkbox:

The default setting of 1 is equivalent to the best server, 2 represents the second best server and so on. 7

In the Resolution field, select a resolution for the array.

8

In the Tile Size field, select a tile size. This size defines the distance in km that each array file is created for. For example, a tile size of 30 will create array tiles of 30 x 30 square km for the entire area of the network you are using for your predictions.

Page 32


The number of tiles that will be generated by your choice of tile size and region is shown below the Tile Size field after you have made an entry in it:

Click Next.

10 Choose whether cell layers will be considered during the creation of coverage arrays and select the layers whose contribution you want to include. You can do this for both the serving and interfering signal. 11 To override the best server selection selecti on algorithm and ignore the contribution of higher priority cell layers without any carrier assignments, select the Consider only sub-cells that have carrier layers with assigned carriers checkbox. This prevents holes in the interference array from appearing when a sub-cell theoretically provides coverage but has not yet been assigned any carriers. 12 In the Thresholds pane, type service level and timing advance threshold values. These thresholds restrict the overall radius of coverage provided by the sub-cell to either the minimum service level or the maximum timing advance, whichever is reached first. For a cell using extended range where two timeslots are used, the maximum timing advance is 133, otherwise the maximum is normally 63. (Within ENTERPRISE these thresholds are set on the Coverage/Interference tab of the Array Settings dialog box which you open by selecting Array A rray Settings from the Arrays menu). 13 In the Cell Parameters pane, select to use sub-cell specific or global values. To use values that you have entered in the Thresholds pane as described above, you must select sub-cell specific. If you select Global Values the values entered in the ENTERPRISE site database are used. (Within ENTERPRISE these thresholds are set on the General tab of the Site Database dialog box which appears when you select Sites from the Database menu and click on an individual cell). 14 Click Next. 15 In the Channel Selection pane, select what type of interference you want to be considered for the interference arrays: 

Co-Channel Only



Adjacent Channel Only



Co-Channel and Adjacent Channel

If you select Adjacent Channel Only or Co-Channel and Adjacent Channel, the value in the Adjacent Channel Offset pane is used to produce the adjacent channel arrays. You can edit this value if you wish. It is also used to produce the adjacent channel curve used in calculating interference.


Page 33

16 In the Interference Options pane you can: Select

To

Use Frequency Hopping

Use Frequency Hopping information when creating arrays. If you have selected Use Frequency Hopping, you can al so choose to use Frequency diversity information when generating arrays. This adds a gain to the serving cell signal to simulate the improvement in C/I that frequency diversity provides. The gain applied depends upon the number of hopping frequencies. For more information on the frequency hopping diversity gain value, see the ASSET User Reference Guide. The interference array calculations also use a BER to/from C/I conversion when frequency hopping is used. For more information on using frequency hopping, see the ASSET User Reference Guide.

Use DTX

Use DTX information when creating arrays. This means ASSET will scale down the power of the transmitter based on the activity factor of the terminal. Using DTX then helps to reduce interference between different cells and to increase the capacity of the system.

Use Traffic

Scale the interference arrays if the traffic load of a subcell is smaller than the potential capacity of the carriers allocated to that subcell. By comparing the channels allocated to a subcell with the number of channels required by the traffic load, the proportion of channels in use ca n be calculated and interference reduced accordingly.

Use Antenna Hopping

Use the antenna hopping gain in the array calculations. Antenna hopping is a transmit diversity scheme in which consecutive bursts of information are transmitted on different antennas. When antennas are exposed to different multipath fading, a diversity gain is achieved. For information on how this gain is calculated, see the ASSET User Reference Guide.

17 In the Erlang Table type pane, select a blocking percentage and select to use either the Erlang B or Erlang C blocking b locking formula. These blocking formulas are described in the ASSET User Reference Guide. 18 Click Next. 19 On the Prediction Parameters page, select Use network element settings or Use overridden settings. If you choose Use network element settings, the creation of arrays is based on the model, resolution and radius settings on the ENTERPRISE Site Database Antennas tab. If you choose Use overridden settings, the creation of arrays is based on your override settings. For more information on these options, see the ASSET User Reference Guide. 20 On the Select Schedule page, indicate whether you wish to run your parameter set manually or every: 

About Tasks When you run a parameter set, ARRAYWIZARD processes it by assigning work units known as tasks to agents. A number of tasks are normally combined into a single "rolled up" task to be sent to an agent. On receiving a rolled up task the agent unrolls it and processes its component tasks. A task that is currently being processed is referred to as a running task. ArrayWizard User Reference Guide 7.0 Creating Arrays Using ARRAYWIZARD

Setting UTM Borders Best server files are generated for tiles even when the tiles overlap a UTM border. When the Best Server data is merged in a tool such as MapInfo, the merged data contains overlapping best server data sets from each UTM zone. Consequently some areas appear to have more than one Best Serving Cell. To prevent this you can specify the westmost and the eastmost longitude bounds of a project. This ensures that each tile generated in a UTM U TM zone that overlaps a UTM border is reduced so that only the portion of the tile within the UTM zone has a best server file calculated. All tiles will then contain best server data only for the UTM zone in which they were calculated. To set UTM Borders: 1

From the Project Settings menu, click UTM Borders.

2

Select the Use UTM border settings checkbox.

3

Enter West Meridian and East Meridian values in degrees to define your UTM border:

Configuring Measurement Based Prediction and Interpolation If you have generated measurement-based pathloss files from your own drive test data (or other area and cell-specific data), you can use these files to t o influence your normal pathloss predictions. The amount of influence they have depends d epends primarily on the percentage weightings that you specify in the Measurements dialog box.

Representative illustration of Combining Predicted Data with Measured Data

If you want to influence the normal pathloss predictions: 1

From the Project Settings menu, select Measurements Settings. The Measurements dialog box appears.

2

Select the Use Measurements in Pathloss Predictions checkbox

3

Enter appropriate percentage weightings, as in this example:

The resulting pathloss value for each pixel that contains measurement-based data would be a new combined value v alue derived from the Measured value and the Predicted Predic ted value, according to the weightings you specify. So, for each pixel, the resulting pathloss value is: w% of Measurement value + (100-w (100-w)% of Prediction value

Page 52


These weightings (and any changes to them) will be automatically invoked whenever you create a coverage/interference array, or when you run the Simulator, or when you use the Pathloss Prediction Generator. If weightings are selected without interpolation, the weightings will only be used at pixels for which measurement data exists. The pathloss value for any pixels where this is not the case will be calculated using 100% pathloss prediction. If you have selected to use measurements to influence pathloss predictions, you can also choose to use interpolation to influence surrounding pixels that do not contain not contain measurement-based data.

Representative illustration of Combining Predicted Data with Measured Data using Interpolation

To do this: 1

Select the Interpolate checkbox.

2

Enter your preferred Roll-off Factor.

The differen difference ce ( ) between between the Measure Measurement ment value value and Predict Prediction ion value value is used used to influence the surrounding pixels. The Roll-off factor, which must be greater than 1, determines the rate at which which the the value value of of reduces as it moves moves from directly adjacent pixels to more distant pixels. The pixels which already contain measurement data are not affected not affected by this interpolation. The resulting pathloss value for each surrounding pixel is: w% of Measurement value + (100-w (100-w)% of Prediction value where the the interpolated interpolated Measurement value is derived derived from an adjusted from the formula:

, derived

Where: = Number of adjacent pixels pixels that contain measurement measurement data (between 1 and 4) = Difference between the Measurement Measurement value* and Prediction Prediction value * (real or interpolated) = Count of each adjacent adjacent pixel (up to maximum maximum of 4) = Roll-Off Factor specified specified (must be greater than 1) ArrayWizard User Reference Guide 7.0 Configuring Settings In ARRAYWIZARD

Page 53

These weightings (and any changes to them) will be automatically invoked whenever you create a coverage/interference array, or when you run the Simulator, or when you use the Pathloss Prediction Generator. If weightings AND interpolation are selected, the weightings and roll-off factor will be invoked at all pixels within the predicted region, including those that do not contain a pathloss prediction value. However, the pixels which already contain measurement data are not affected not affected by interpolation.

Configuring Carrier Wave Measurements You can include drive test data from measurement-based pathloss (.plc) files when creating your pathloss predictions. To do this: 1

From the Project Settings menu, select Measurement Settings.

2

Select the Use measurements in pathloss predictions checkbox.

3

Type in the required percentage weightings.

You can also choose to use interpolation to influence the prediction for the area surrounding the measured data, and you can specify the extent of this influence. To do this: 1

Select the Interpolate checkbox.

2

Type in the required Rolloff factor.

For more information on using measurement-based pathloss files to influence pathloss predictions, see the ASSET User Reference Guide.

About the ARRAYWIZARD ARRAYWIZARD Settings Settin gs Dialog Box You can use the ARRAYWIZARD Settings dialog box to: Indicate that succeeded tasks will be deleted automatically. Indicate that a forced shut down will always occur when you shut down an agent. If you do not select this option, ARRAYWIZARD gives the server three minutes to close down cleanly, then then prompts for a forced shutdown. Indicate that rolled up tasks are to t o be given a low l ow priority. Indicate that log files are to be truncated at a specified size. Indicate that log files are to be truncated at a specified age.
