Abstract

PURPOSE:To prevent interference of a radio wave without provision of two sets of receivers respectively to a base station and each of mobile stations by allowing the base station and each mobile station to decide the operating channel in response to the received electric field of a mobile station respectively. CONSTITUTION:An electric field detection output terminal 14 of a base station 1 and an electric field detection output terminal 25 of a mobile station 2, and an electric field detection output terminal 15 of the station 1 and an electric field detection output terminal 24 of the station 2 are connected electrically respectively in the standby state. Thus, a control section 13 of the station 1 monitors the idle state of reception and transmission channels simultaneously at all times. In the station 2 also, a control section 23 of the station 2 monitors the idle state of reception and transmission channels simultaneously at all times through the similar connection. In case of calling, the station 2 is disconnected from the station 1 to go to communication, but only when both the channels are idle as the result of monitor of the channels, the station 2 sends a transmission radio wave to start the call connection. Similarly, the station 1 starts the incoming reply connection only when both the channels are idle. When both the stations completes the communication, the stations 1, 2 are connected and they are brought into the standby state.
