Mosaic Testing Guidelines 2. Purpose

The purpose of this document is to highlight minor changes and streamline the testing procedure for all Consolidation/Infill sites been built across each Operators Network. This revised testing guideline will cover the required spectrums that each Operator uses. And capture the same information previously delivered using each operator respective Testing Specification.

2.1 ChangesTest engineers should revert back to the guidelines provided by each operator as both Testing Specifications are very similar for the tests being carried out on sites going forward. However, some changes have been made to System tests going forward and are as follows;

[2.1.1] The ASC/WTMA will not be included in the SRL testing for Meteor Only with the inclusion of all markers as per the uplink and downlink bands below in Table 2. For sites that have cavity combiners as part of the system separate SRL tests are required for both O2, and MMC and H3GI given the “uplink” & “downlink” frequencies o indicatedn below in table 3.

[2.1.2] Limits are defined in new MOSAIC rigging test sheet.The limit for Meteor Only SRL test on UMTS will now be 15.5dB the value determined within the Downlink (Tx) band only is required.

[2.1.3] The limit for all other SRL tests across the full bandwidth spectrums will now be 14dB

2.1.1[2.1.4] The labelling convention for all “stored plots and documentation” are to be “A, B, C” convention.

Mosaic Testing Guidelines 3. Changes to Spectrums

3.1 When setting up the Site Master for testing whichever band in question simply extend the lower and higher limits to take in all threeboth operators spectrum as shown in Table 1 below.

LTE 800 MHz 786 – 857 MHz

U/GSM 900 MHz 875 – 965 MHz

LTE/GSM 1800 MHz 1705 – 1885 MHz

UMTS 19100 – 2180 MHz

Table 1

For the full system test i.e. SRL simply extend the “Markers” on both the Uplink and Downlink bands for LTE 800, U/GSM 900, LTE/GSM 1800 as shown in Table 2 below.

*For SRL tests on the LTE/GSM 1800, separate tests are to be carried out showing the specific uplink and downlink bands assigned to each operator

For UMTS, theThe ASC/WTMA will notw be included in the SRL test with the inclusions of markers 1, 2, 3 & 4 as per the uplink and downlink bands also in Table 2 below.

Table 2

Use the specific ports assigned for tests through the 900 ports of cavity combiners for both O2 and MMC and H3GIas these are operator band specific assigned frequencies.

Uplink (Rx) Downlink (Tx)

LTE 800 MHz 791 – 811 MHz 832 – 852 MHz

U/GSM 900 MHz 880 – 915 MHz 925 – 960 MHz

*LTE/GSM 1800MHz

(THREE ONLY) 1750 -1770 MHz 1845 – 1865 MHz

*LTE/GSM 1800 MHz

(O2 ONLY) 1710 – 1725 MHz 1805 – 1820 MHz

*LTE/GSM 1800 MHz

(MMC ONLY) 17765 – 1785 MHz 18650 – 1880 MHz

UMTS 1920 - 1980 MHz 2110 -2170 MHz

Mosaic Testing Guidelines 4. T est to be carried out

The tests required from each installation will be determined on whether the antenna system is been interfered with or not or whether it is anew installation as with the current Three rollout on Infill and NRA sites.

4.1 Radio Logical Share Tests

When installing a Radio Logical share solution and not interfering with the Antenna system one SRL sweep of each Antenna line System is sufficient given the steps on page 2 are followed.

SRL - System Return Loss to Antenna (ASC/WTMA not included (MMC Only) for UMTS systems)

4.2 Tests of the system when Introducing Hardware

When carrying out the following on a system;a) Replacing antennasb) introducing Air Cavity Combinersc) ASC/WTMA swap out (faulty) or upgrade

The following system tests should be carried out prior to work on the system to determine the status of the system pre-works. See below the test to be carried out when this is the case.

PRE-SRL - System Return Loss to Antenna (ASC/WTMA not included (MMC Only) for UMTS systems)

Once all works is carried out 1 SRL sweep of each Antenna line System is sufficient to determine the status of the system. See below the test to be carried out when this is the case.


*When testing through the 900 ports of a Cavity Combiner separate SRL test for both O2, and MMC and H3GI will be required. Markers must be set as per the values on Table 21 above to each operator’s specific Uplink and Downlink band. Then marker 5 peaked between 1 & 2, marker 6 peaked between 3 & 4. Markers for H3GI and peak to be added. These additional test are only required when testing 900cavity combiners. See below the test to be carried out when this is the case.

*SRLO2 - System Return Loss to Antenna (900 System with Cavity Combiners) (Ref; Table 2)

*SRLMMC - System Return Loss to Antenna (900 System with Cavity Combiners) (Ref; Table 2)


4.3 Re-terminated feeders Tests

When the feeders on a system are re-terminated the following system tests should be carried out prior to work on the system

PRE-SRL - System Return Loss to Antenna (ASC/WTMA not included (MMC Only) for UMTS systems)

Once all works is carried out the following tests must be carried out

MFRLL* - Main Feeder Return Loss to Load (Main feeder only)

*This test is only required when antenna works is been carried out on site in conjunction with the re-termination on the feeder at ground level.


4.4 Three Installation feeder Tests

When carrying out new Three installations following system tests should be carried out post installation. All data captured in the tests below will allow full completion of the Rigging Acceptance Document which will replace the previous VC4 form.

DTFL - Distance to Fault to Load

To get main feeder lengths

MFSC - Main Feeder Short Circuit

To get loss of main feeder only, calculated tail losses will be added in spreadsheet

SRLBYP - System Return Loss Bypass TMA

Return loss on all paths through diplexers/combiners up to the antenna ports – but physical by pass the TMA


5. Examples of tests to be captured

Example for point 4.1For a Radio logical share solution while not interfering with the antenna system based on a three sector site a total of 1 test per cable, per technology band (800/900/1800/UMTS) total - 6 SRL tests (12 for dual-band or 18 tests for a tri-band site or 24 for four band site) are to be carried out.

Example for point 4.2If antennas are to be replaced or additional hardware are introduced to the system and based on a three sector site a total of 2 tests per cable, per technology band( 800/900/1800/2100LTE/GSM/UMTS) 1 pre-test, 1 post-works test –total 2 tests per cable (12 tests for single technology, 24 tests for dual-band, and 36 tests for tri-band ad 48 for four bands) are to be carried out. *When Testing through the 900 ports of a Cavity Combiner separate SRL test for O2, and MMC and H3G are required to be carried out, thus adding a total of 96 tests per three sector site (for 900 onlyexample) (Ref; Table 2).

Example for point 4.3If the feeders on the system are re-terminated and there is antenna works been carried out based on a three sector site a total of 3 tests per cable, per bandtechnology (LTE/GSM/UMTS800/900/1800/2100) 1 pre-test, 2 post-works test –total 3 tests per cable (18 tests for single technology, 36 tests for dual-band, and 54 tests for tri-band, 72 for four band) are to be carried out. If no antenna works is been carried out then 2 tests per cable, per technology (900/1800/UMTS) 1 pre-test, 1 post-works test –total 2 tests per cable (12 tests for single technology, 24 tests for dual-band and 36 tests for tri-band) are to be carried out.

Example for point 4.4Where troubleshooting is required because of poor test results make sure to eliminate the possibility of Vodafone antennas in close proximity or adjacent to installed antennas. Each operator’s spectrum would need to be specifically tested and not across the full bandwidth spectrum which includes Vodafone’s spectrum (Excludes LTE 800 spectrum).


6. Feeder Attenuation and Velocity Factor

The host site cable type will determine the feeder cable attenuation and velocity factors that will entered into the Site Master database. These values can be obtained from each Operators Testing Specifications.

7. Plot/Documentation labelling Convention

All stored plots and documentation are now to be “A, B, C” convention as opposed to 0, 1, 2 or 1, 2, 3. (Feeder labelling on site will remain as per the host convention down to the Air Cavity Combiner then guest labelling convention will be used on the jumpers from the Air Cavity Combiner to RBS)

8. Summary

Always investigate if test results are borderline, even marginal passes. All new systems should clearly pass, if not then there’s something wrong.

Don’t just walk away and expect it to be OK!
