Antenna and environmental conditions monitoring for wireless and telecommunications for private, public, first responders, and emergency responder radio communication system (ERRCS)
Antenna monitoring systems and methods can include, among other things, a transmitter near each of the antennas in a distributed antenna system (DAS). The transmitter can transmit an antenna identifier corresponding to that antenna, so that the various transmitters in the DAS each transmit different antenna identifiers. These antenna identifiers can be detected by a receiver and can be processed to determine whether any antenna identifiers are missing. If any expected antenna identifier is missing, the receiver can infer that the antenna or a component associated with the antenna (such as cabling) may have failed. The receiver can then output an indication or notification that may be accessed by maintenance personnel and/or emergency personnel to enable them to identify and repair the non-functioning antenna or component. The transmitter can transmit other data, such as environmental data, RF data, or the like, to facilitate additional or alternative monitoring functionality.
