发明名称 Communication system
摘要 A communication system comprises at least one first wireless tag for identifying a first apparatus location area, at least one second wireless tag for identifying a second apparatus location area, a transmitter, and a receiver. The transmitter, when residing in the first or second apparatus location area, outputs a wireless ID read signal to read the ID of the wireless tag in the area, multiplexes the read ID on a communication signal, and transmits the resultant communication signal. The receiver, when residing in the second or first apparatus location area, outputs a wireless ID read signal to read the ID of the wireless tag in the area, determines whether or not an ID identical to the read ID is multiplexed on a received communication signal, and determines that the communication signal is addressed to the receiver itself when the ID is multiplexed.
