Abstract
A communication apparatus to which communication units for communicating in accordance with a multichannel access method are connected comprises a receiver to receive ID information of a communication channel to be used from the plurality of communication units, and a selector to select the communication channel in accordance with the ID information received by the receiver. Namely, the selector selects the communication channel other than the communication channel such as to exert an influence on a control channel or other communication channels if it is used together with the in-use communication channel. Or, now assuming that a frequency of the in-use communication channel is set to f.sub.A, the selector selects the communication channel other than the communication channel of a frequency f.sub.B such that (2f.sub.A -f.sub.B) or (2f.sub.B -f.sub.A) is equal to the frequency of the control channel or the frequency of the other communication channel.
