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 included therein transmitted from the master unit to measure the received signal strength indication for downlink (RSSI_D), assemble the response packet having the measured received signal strength indication for downlink (RSSI_D) and transmit the monitoring radio signal having the assembled response packet to the master unit.
