The embodiment of the invention discloses a method for selecting a channel and a communication system. The method for selecting a channel comprises the following steps: acquiring interference electrical levels of working sub-bands of all logic channels; comparing the magnitude of the interference electrical levels of the working sub-bands of all the logic channels; and selecting the logic channelwith the small interference electrical level of the working sub-band as the logic channel for sending a newly created beacon period. The communication system comprises an acquisition unit, a processing unit and a selecting unit, wherein the acquisition unit is used for acquiring the interference electrical levels of the working sub-bands of all logic channels; the processing unit is used for comparing the magnitude of the interference electrical levels acquired by the acquisition unit; and the selecting unit is used for selecting the logic channel with the small interference electrical level of the working sub-band as
