Classification: CPC H | IPC H

Claim 6:
7. A distributed antenna monitoring method used in a public safety radio network, the method comprising:
producing and transmitting, by a master unit, a diagnostic packet to a remote unit;
disassembling and analyzing, by the remote unit, the diagnostic packet to measure a received signal strength indication for downlink (RSSI_D);
producing, by the remote unit, a response packet having the received signal strength indication for downlink (RSSI_D);
transmitting, by the remote unit, the response packet to the master unit through a service antenna of distributed service antennas;
disassembling, by the master unit, the response packet to measure a received signal strength indication for uplink (RSSI_U);
analyzing, by the master unit, the received signal strength indication for downlink (RSSI_D) and a received signal strength indication for uplink (RSSI_U) to determine whether or not an abnormality occurs in the service antenna;
transmitting, by the master unit, an antenna diagnosis result to a monitoring server; and
allowing the monitoring server to perform a statistical processing and visualization on antenna diagnosis information and to notify an administrator of the antenna diagnosis information.
