Abstract
A distributed antenna system includes a plurality of remote antenna units with a passive element coupled to at least one of the remote antenna units at a connection juncture. An RFID system is associated with the first passive element and has RFID data identifying the first passive element. An interrogator unit is associated with the remote antenna unit and is configured for generating a least one signal for transmission to the passive element to be reflected at the connection juncture and received at the interrogator unit. The interrogator unit is also configured for generating at least one signal for transmission to the RFID system to obtain the RFID data identifying the passive element. Processing circuitry processes the reflected signal and measures a parameter of the first passive element. The processing circuitry correlates the measured parameter with the RFID data for the passive element.
