Communication frequency selection method and device and computer storage medium

The invention provides a communication frequency selection method and device and a computer storage medium. The communication frequency selection method is applied to a communication device. The communication frequency selection method comprises the following steps: obtaining a first communication frequency range of itself and a second communication frequency range connected with the communication device, and obtaining a common communication frequency of the first communication frequency and the second communication frequency; searching an idle communication frequency in the public communication frequency range in the communication range according to preset rules; and establishing a communication channel with the connection communication device based on the idle communication frequency, and performing data transmission. Through the above mode, according to the communication frequency selection method, the idle communication frequency is selected to establish the communication channel, the utilization rate of
