FFAX (Find Faulty Antenna eXpert)

The purpose of FFAX is to provide an efficient way to remotely identify RF paths and antenna installations that are not performing according to expectations.

This is done by monitoring the difference in received signal strength from different RX paths in the BTS.

FFAX in OSS is applicable for the uplink and requires the BSS feature Find Faulty Antenna Data (FFAD). FFAX enables managing of cell sets to monitor, presentation of results in real-time and database storage functionality. For each reported TRX, key values are presented representing the accumulated receiver signal strength difference, during the measurement period, and when relevant an indication of the most likely fault or no fault found. The report will be updated every minute, and can be viewed in table as well as graph format (sliding window displaying data for the last hour). This is ideal during site visits where results of changes to the RF paths can be immediately seen in OSS.
