ABSTRACT:
A channel selection system for radio communication equipment which uses a control channel for interchanging control signals for connection and a plurality of data channels for interchanging data and emits an electromagnetic wave by using any one of the data channels after determining that it is idle by carrier sensing. The system rarely selects a data channel adjoining the control channel since the probability that such a data channel is registered as an idle channel is extremely low. The system, therefore, reduces the possibility of the equipment being unable to use the control channel due to the influence of power leaking from the data channel adjoining the control channel.
