Macro Base Station Installation Procedures (NPM-1000)
Acceptance Test Plan for Base Station Upgrade
After completing the upgrade, review the Acceptance Test Plan (ATP) to verify the functionality and
performance of the new configuration.
Site Coverage Verification
Immediately after performing the cutover and quality audit, verify the RF site coverage to identify
possible problems with the antenna subsystem, such as antenna radiation patterns, azimuth, tilt, or
cabling errors.
Coverage verification includes performing a drive test on non-service-affecting channels, such as the
pilot channel (PICH). Service interrupt may be required if adjustments to the antenna subsystem are
required.
Voice and Data Functionality and Performance
The ATP should include procedures that test the functionality and performance of the voice and data
services.
RF Network Coverage Optimization
RF network coverage optimization should be performed after the upgrade is completed for all planned
sites within the market area in order to secure high service quality and subscriber satisfaction.
Network optimization typically requires:
Monitoring network statistics to identify areas or users with service quality degradation
Drive testing (pilot channel scan) to identify areas with coverage problems
Collected data should be analyzed and, if necessary, appropriate site configuration changes
implemented (such as antenna orientation, down tilt, base station power setting, individual channel
power allocation, or parameter tuning).
In situations where a configuration change for a large number of sites is planned, sector upgrades
should occur in several phases. The entire network should be divided in clusters of sites and
sectorization performed for each cluster individually. Coverage optimization should be performed for
each cluster after sectorization is completed. Network wide optimization will be performed after entire
network is reconfigured.
