RET Antenna Installation Using Kathrein PCA)

Radio Datasheet 7186

VET Antenna Installation - Guidelines on use of Kathrein Handheld PCA and Software

This datasheet is compiled and owned by Radio Engineering. Date of last update : 22 September 2010.

SUMMARY:

O2 (UK) deploys a number of VET antennas in the network build programme. These antennas require special procedures and tools when deployed, and when future optimisation is required. Currently all VET UMTS antennas are supplied by Kathrein, Jaybeam and Powerwave and Argus. This Datasheet defines the installation and software configuration of VET antennas using the Kathrein handheld Portable Control Control Adaptor (PCA), and also gives details for configuring the NSN MHA (AISG WMHD version). It should also be noted that use of the old Sigma VET control software is not longer approved for use on any O2 antenna system. This Datasheet (V3.3) has been updated with information regarding VET Motor configuration for UMTS 900 deployment (Page 8, Paragraph 7)

Target Audience

This Datasheet is intended for use by anyone required to install or work on O2 UK RF antenna line systems.

General Information

VET installation work may only be performed by suitably trained personnel. All rigging engineers must have access to the correct software tools and fully understand all commissioning commissioning and set up procedures prior to working on any AISG controlled antenna or MHA system When installing VET antennas, the following items will will be required, in addition to the normal antenna installation tools:-

VET Antenna Use

VET Antenna Installation - Guidelines on use of Kathrein Handheld PCA and Software A VET antenna will generally be the standard antenna type deployed, therefore the only use of fixed tilt antennas are on legacy deployments and when needed for maintenance maintenance replacement. Although VET antennas will will be deployed, a VET motor and associated leads may not always be required. The guidelines given given here are to assist Radio Planners and build contractors as to when it is appropriate to deploy antenna which can be remotely tilted In general, an antenna must be deployed as remote tilt unless the antenna may be manually optimised using the following guidelines:guidelines:1)

No outage is required for any antenna on site

2)

The antenna is accessible by a person who is not a qualified rigger

3)

The antenna can be accessed with no “access fees” payable i.e. sites such as Arqiva often incur a charge for access. In this situation, remote VET antennas should be deployed, even if they follow the above guidelines, as long as the VET box can be accessed without without incurring charges.

In general, this will only apply to rooftop sites where the antenna may be easily accessed by a non rigger person VET Control Cable

A VET antenna installation will be any combination of single band, Multiband or Triband antennas on any given site. Each antenna may either use a separate control cable, or 2 or more antennas may be “Daisy chained” chained” together, using control cables looped from one antenna to the next, with one main cable back to the BTS equipment. Antennas from different manufactures, manufactures, and of different operating frequencies may be mixed on site, and daisy chained together onto a common VET control cable The maximum cable length to any antenna should not exceed 150m. If daisy chaining antennas together, installers must ensure that the total the total control control cable length doesn’t exceed 150m 15 0m (Note: There is not an actual firm cut off point for the length of the VET cable, and will depend on site specific conditions, however, installers should note that problems may be encountered if the run exceeds 150m) antennas, being deployed by O2 from January 2010 for 6 sector Note: Argus antennas, working, don’t have the facility to daisy chain antennas, as they have one AISG po rt only. When deploying Argus antennas, the Kathrein AISG splitter box, Part number 860 10002, should be used, as shown below.

Kathrein VET Cable Junction box (Approx. 91 x 103 x 72mm) Note: The Kathrein junction box must be used in the correct orientat ion, with the AISG connectors situated at the bottom, facing downwards.

The unused AISG port of the last antenna must be sealed by a cap or other appropriate method. This is shown in Diagram 1 below. Use of Kathrein Multiband or Triband antennas will require that a short (typically 500mm) jumper cable is used to daisy chain the UMTS and GSM motors together.

In some situations, it will be appropriate to use a mixture of the above methods. When for example 2 antennas on a roof top are closely spaced, then these antennas can be daisy chained, and a third antenna which may be somewhat further away, will have a separate control cable. Control cables and VET termination boxes are available from the following:GCA Ltd Ronell Place Unit 2 41A Shirehill Industrial Estate Saffron Walden Essex CB11 3AQ

Control cables should be clamped along with the main feeder run using appropriately sized clamps, as defined in D&S6130 and spaced at the same distances as the feeder clamps. Where the control cable is fixed directly to the feeder cable tray, then the use of tie wraps is allowed. Care must be taken when fixing the control cable dir ectly to the feeder tray that any sharp edges which may cut into and damage the cable are avoided, or suitable protection applied. T he cable should as a minimum be fixed every 1m, however, in some situations (i.e. on corners or bends) closer tying may be required, and common sense must be used. In all situations, the control cable must be fixed so that no potential trip hazards are present, and to help avoid this, wherever possible, should be fixed to the inside of the tray, not the outside.

VET Cable Termination Box

VET Antenna Installation - Guidelines on use of Kathrein Handheld PCA and Software A VET cable termination box (pictured b elow) must be used to terminate the control cable on all new build sites deploying VET antennas. The bo x must be deployed in the nearest location possible to the BTS equipment, and within 3m of a suitable 240v Power supply. VET termination boxes are supplied by both GCA and ICD (Address as above), and are supplied with a number of mounting options.

VET Motor Serial Numbers

VET Motor Connection

VET Antenna Installation - Guidelines on use of Kathrein Handheld PCA and Software Kathrein antennas use a separate VET motor for each individual frequency band. It is vital that the VET motor and UMTS MHA locations are known, and the serial numbers are correctly recorded on the ASICC sheet. When configuring the VET Motors after antenna installation, the motor serial numbers and locations will be required All Kathrein antennas are delivered as manual VET versions, and the motor must be obtained separately at the time of order. The detailed installation instructions provided with the antennas and motors must be followed. With the exception of the 800 10314 antenna with integrated motor – See page 20 for further information, all Kathrein antennas will require the VET motor to b e configured with the correct antenna data information. To ensure installers have the correct antenna information, the latest Device Data software file must be used. As of Jan 2010, this is version 2.02. Kathrein VET motors a re supplied with a termination connector which must be fitted to any unused ports Jaybeam and Powerwave antennas have the VET motors factory installed and configured, and should not be removed prior to installation. Argus antennas have preconfigured, integrated VET motors which cannot be removed.

VET Motor Configuration

Note: The screen shots 2 to 21 below show an earlier version of the Kathrein software, however, the procedure is the same as when using V2.1.1 software. The MHA configuration section shows the correct V2.1.1 software version. When configuring the antennas the following step – by – step instructions must be followed. Note: The following notes show a single Kathrein triband antenna configuration process, however, all Kathrein antennas, and other non Kathrein antennas are all generally configured in the same way. Where different procedures are required, these are given in the Section “Use of Kathrein V2.1.1 Software with non Kathrein antennas ” commencing on Page 26

1.

Connect up all VET motors (using appropriate daisy chaining where more than one motor per antenna is required) and the main antenna to VET termination box cable, using a short VET control cable to connect the PCA controller to the termination box.

2.

Connect the PCA controller to the PC and launch the Kathrein software. The screen will show “SCANNING” as it is finding the VET motors

Screen Shot : Step 2. New motors, Softw are scanning 3 VET motors for information 3.


It is important to check that the expected number of motors are actually detected and shown. i.e. for a 3 sector site using triband antennas, 9 motors will have been installed and should be displayed, with serial In Confidence

Page 6 of 31


VET Antenna Installation - Guidelines on use of Kathrein Handheld PCA and Software numbers corresponding to those previously recorded. If the correct number of motors are not shown, then the missing motors should be checked for correct connection. It should also be noted that the serial number will not be shown in any predefined order, but will be random, even if they have been installed in sequence. The motor serial number is the only indication of the location of the motor, which will correspond to the previously recorded motor / antenna location. 4.

Once the Software has read the information from the VET motors, the “Status” boxes will show “ ERROR” as shown below, as no antenna configuration information will have yet been entered into the motors. With the exception of the UMTS only antenna, type number 800 10314 (See page 20 for configuration details of this antenna), the “Antenna Type” boxes will also be empty, as no antenna type will have yet been entered. The motor serial numbers shown on the screen will correspond to the VET motors connected to the relevant antenna ports as shown on the label on the motor. The motor serial numbers MUST be entered into the ASICC sheet in the relevant space in the “System Information” page.

The antenna type must be filled in with the correct frequency information for that motor from the drop down list on the screen. The motors have a unique serial number, shown on the label on the motor, and will appear on the screen in the “Serial Number” boxes. The example shown below is taken from a 1.5m 742 270 Triband antenna. Multiband antennas (2 motors per antenna), and single band antennas (1 motor per antenna) will be similar. It can be seen from the screen shots below that there are 3 configuration files for this antenna. One for the GSM 1800 band (Shown as 742 270 1710-1880 MHz) one for the GSM 900 band (shown as 742 270 806-960 MHz), and one for the UMTS band (Shown as 742 270 1920-2170 MHz). It should be noted in the example below that the motors are ordered 1800, 900, UMTS, however, the motors will not necessarily be in this sequence, but will be random, and different for each install. The motor controlling each set of ports must be filled in with the correct frequency band for that motor. i.e. in the example given, motor serial number CS62705016 controls the GSM 900 band ports and the 742 270 806-960 MHz information must be selected

Kathrein 800 10314 UMTS only antenna with integrated VET motor Software Configuration

The Kathrein UMTS only 800 10 314 (O2 Quantum code 65XV10UR13K ) VET antennas require a slightly different set up procedure to other Kathrein antennas. Due to the use of an integrated VET motor, the antenna is pre-configured from the factory, and does not required the antenna type to be selected from the drop down box. When configuring this antenna type, the following instructions must be followed.

1.

Connect the PCA controller to the PC and launch the Kathrein software. The software will initially show “Scanning…..” (see Screen shot below)

Use of Kathrein V2.0 Software with non Kathrein antennas General Information

Kathrein V2.1.1 Software may be used with Jaybeam, PCTel (Sigma) and Powerwave antennas, albeit with a few limitations. Note: The V2.1.1 software has solved many of the issues of compatibility with non Kathrein antennas over the older V2.0 software previously used. In general, the instructions given above for use with Kathrein antennas is also relevant for use with other manufacturers antennas. The following notes give indications of differences that will be encountered and solutions.

Items Relevant to all Non Kathrein Antennas Initial Device Scan

Problem . When the software is opened, and the initial Device Scan starts, an error message “No Devices! ” may be shown (See Screen shot below) Note: This is usually shown with Sigma antennas only, however, may also be shown with other non Kathrein antennas

Screen Shot. No Devices found Solution. Click on “OK”, and click the “ Devices Status ” tab, which will re-start the device scan, and find all connected motors. (Note:, if “ No Devices! ” message shows again, click on “ OK” and repeat the “ Devise Status ” scan


In Confidence

Page 23 of 31



Items Relevant to all Sigma (PCTel) Antennas Sigma AISG V1.0 Antennas

Problem . Older Sigma antennas using AISG version 1.0 will not work correctly with Kathrein V2.1.1 software due to a pin configuration change. These antennas were supplied until approx end 2004. If the Kathrein V2.1.1 software is being used with older Sigma antennas and they cannot b e seen by the software during a normal scan, then it is likely that the antenna is an AISG V1.0 antenna. Solution. A modified VET cable with a reconfigured PIN connection from GCA must be used. This cable comes with a red coloured jacket, and are marked as “O2 AISG 1.0 to 1.1 Pin reversal cable” (See photo below) These cables have 2 of the pins reversed, which in effect changes an AISG V1.0 into V1.1 configuration. It is important that this cable is only used with Sigma V1.0 antennas, as if is used on standard AISG V1.1 antennas, then they will in effect be turned back into AISG V1.0 antennas which will not be recognised by the Kathrein software. If Sigma V1.0 and V1.1 antennas are mixed on site, then the VET reversal cable should be permanently installed at the V1.0 antenna only. If access to the antennas is not po ssible, then the AISG antenna should be set with no crossover cable used – at this point only AISG V1.1 antenna will be seen. The Crossover cable should then be added at the output of the PCA, and the software re-started, at which time the V1.0 antennas will be seen. Note: Only early Sigma antennas (Up to approximately end 2004) were deployed as V1.0. No other manufactures antennas were deployed with V1.0 software. If any of these antennas are removed from site (i.e. for maintance or upgrade work) then they MUST NOT be re-installed in the O2 network O2 REB 068 gives further information on this requirement.

Items Relevant to all Jaybeam Antennas CMD_TIMEOUT

Problem . Jaybeam antennas have been known to occasionally come up with “CMD_TIMEOUT” errors during tilt setting functions, particularly when going to the extreme ends of the tilt ranges.

Solution. The Software should be closed down and re-opened, and allow the motors to be rescanned. Once this has been completed, the Error Status box should show “OK” , and should show the correct tilt setting. If the c orrect tilt setting is slightly off (i.e. reads 9.8 Deg rather than 10.0 Deg), then the user should attempt to move the antenna to the required value using the normal “Set Tilt” function. If “CMD_TIMEOUT” occurs again, then the VET motor should be left at the tilt position (i.e. 9.8 deg) to perform the required System return loss test, the software restarted to clear the error, and a note to this effect added to the comments box of the Report File. The normal configuration should then be continued, and the antenna set to its final required tilt setting. NOTE. A simple “Device Status” rescan will not correct the “ CMD_TIMEOUT ” error. The software MUST be closed down completely and re-opened to solve this problem Note: ALL JAYBEAM ANTENNAS ARE SELF CALABRATING AND DON’T REQUIRE FIELD CALIBRATION.

Items Relevant to all Powerwave Antennas Configuration File

Problem . Powerwave antennas which do not have the configuration file loaded into the VET motors Solution. There is no direct solution to this problem, as the Kathrein software is not capable of loading the configuration files into the Powerwave antennas VET motors. All Powerwave antennas which are required to be remote tilt versions should be purchased with the motor already fitted in the factory. This will ensure that the configuration file will have already been pre-loaded in the factory, and the antenna can then be configured as normal. If a new clean motor which has not be configured is used, (i.e. a faulty motor has to be replaced) please contact Dave Westrup (07860 378369) for assistance

Configuration of NSN WMHD UMTS MHA’s th

General

From January 11 2010, O2 will introduce an additional requirement to configure all NSN supplied AISG UMTS MHA’s (Version WMHD only) to minimise incorrect sector identification, particularly in respect to 6 sector working. These MHA’s may be configured with the same Kathrein PCA box and software as for VET antennas, and broadly follows the same labelling format as for VET antennas and feeders [1]

MHA Configuration Method

The MHA may be configured prior to, or after installation, however, as with VET antennas, it is vitally important that once an MHA has been configured with sector ID information, then the MHA must be installed on that sector, otherwise when the MHA is scanned by NSN during integration, then this will result in crossed sectors which will involve a site visit by the rigging contractor to resolve. When configuring AISG MHA’s, the following items will be r equired:-

MHA Configuration

1.

Kathrein Handheld PCA box Note: If using the older PCA, then the 15V power input must be used, otherwise the PCA is unable to read the MHA. Additionally, if using the earlier PCA, then the current draw option is not available.

2.

VET Control cable

3.

Kathrein Smart Bias T, Part number 782 10253

4.

Laptop PC with Kathrein Version 2.1.1 PCA Software, with Device Data file version 2.02.

All AISG MHA’s must be configured with the Kathrein Software V2.1.1 and handheld PCA controller as for VET antennas. The VET control cable will now be connected to the Smart Bias T as shown below. When configuring the MHA’s the following step – by – step instructions must be followed.

1.

Connect the AISG lead to the Kathrein Smart Bias T “Port DC RCU”, and the RF lead to “Port 2 Feeder” as shown below. Note: no connection is made to “Port 1 Antenna” If the MHA is being configured after installation, then the Smart Bias T “Port 2 Feeder” is connected to the BTS end of the main RF feeder. If the main feeder is terminated in a female connector, then a short Male to Male jumper will be required.

2.

Connect the other end of the RF lead to the MHA “BTS 1” port as shown below.

Connect the PCA controller to the PC and launch the Kathrein software. The screen will show “ SCANNING” as it is finding the MHA. Note, if the Smart Bias T is connected to the wrong MHA port, then an error message showing “No Devices Found!” will be shown.

4.

Once the MHA is detected, the screen as seen below will be shown.

5.

Click on the Wizard Setup tab, this will take you to a screen as shown below.

Configure Sector ID-0 and 1, I nstaller ID and Basestation ID, in the same format as for configuring VET antennas. Both Sector ID-0 and ID-1 must be configured with the same information, i.e. 1U21. Follow the same “Set Data – Write Data – Finish” procedure as for VET antennas. Once completed, click on the “Details” tab, and the following screen will be shown. For a correctly working MHA, the Status should show as OK, as below. If ERRORS are shown, then click the “Reset” and “Clear Errors” tabs. If the MHA still shows errors, then the MHA should be swapped for a new MHA. For the WMHD MHA currently deployed by O2 UK, the “Get Mode” and “Get Gain” tabs are not settable functions. The Serial number shown will correspond with the serial number shown on the side of the MHA (as shown in Photo below), and is the number which must be entered into the ASICC sheet.
