Amosphere NPM Installation Procedures (MMDS)
Acceptance Test Plan for Basestation 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).
