Abstract
An interrogation system for enabling transmission and/or reception of RF signals by a communication system. In accordance with the present invention, an interrogation is performed between a transceiver and an antenna prior to the transceiver transmitting or receiving RF signals via the antenna. The interrogation is used to determine whether the antenna transmits and/or receives RF signals having the power and/or frequency band required by the transceiver. The interrogation is performed by an interrogating device transmitting an interrogation signal to the other, responding device. The responding device transmits a response signal to the interrogating device in response to receiving the interrogation signal. The interrogating device determines if the response signal has a predetermined characteristic. If the response signal has the predetermined characteristic, transmission and/or reception of RF signals is enabled. An alternative use of the interrogation is to identify which one of a plurality of antennas connected to the transceiver is to be used to transmit or receive RF signals.
