Case Study: Tier-1 US Service Provider eliminates rogue interference with VIAVI Solutions

Zeroing in on an Interference Source with VIAVI InterferenceAdvisor and AntennaAdvisor

VIAVI Solutions helped a Tier-1 US Service Provider in Nashville, TN, troubleshoot a sudden rogue interferer that was causing high noise on PRB 19 across several downtown macro sites near Bridgestone Arena. The interference source was difficult to locate because dense urban buildings reflected the RF signals, making the direction unclear.

Using VIAVI InterferenceAdvisor, EagleEye software, and then VIAVI AntennaAdvisor, the team first narrowed the affected area by drive testing and then pinpointed the source on foot to a nearby brick building. After discovering an unlicensed wireless repeater installed in the building, VIAVI Solutions helped the provider shut it down and verify with CellAdvisor that the interference was gone, resolving the issue in less than two hours and protecting network performance.
