Abstract
The present disclosure relates to a distributed antenna monitoring apparatus for monitoring antennas of a distributed antenna system (DAS) installed in a building in a public safety radio network, and a method therefor. The distributed antenna monitoring apparatus disclosed herein includes: a radio coupler configured to couple a monitoring radio signal to be transmitted and received to and from distributed service antennas; a master unit configured to transmit the monitoring radio signal having a diagnostic packet included therein to the distributed service antennas through the radio coupler, and receive a monitoring radio signal having a response packet included therein from each of the distributed service antennas to measure a received signal strength indication for uplink (RSSI_U), analyze the measured received signal strength indication for uplink (RSSI_U) and a received signal strength indication for downlink (RSSI_D) to monitor a state of each of the distributed service antennas; and a plurality of remote units respectively connected to the distributed service antennas through radio links, and each configured to receive the monitoring radio signal having the diagnostic packet…
