The invention relates to the technical field of
wireless communication, in particular to a channel
selection method and device and communication equipment, and the method comprises the steps: monitoring the data packet receiving and transmitting condition of each channel group in real time, and calculating to obtain the packet delivery rate of each channel group; the channel group is obtained by compounding a plurality of adjacent channels; arranging the packet delivery rate of each channel group in a descending order, and determining the priority of each channel group; carrying out subtraction
processing on the packet delivery rate of each
adjacent channel group, and determining a packet delivery
rate difference value between each channel group and the
adjacent channel group; according to the packet delivery
rate difference value between each channel group and the
adjacent channel group, determining a plurality of available channel groups of which the packet delivery
rate difference value exceeds a preset threshold value; and starting the plurality of available channel groups, and disabling the channel groups except the available channel groups. According to the invention, the
trial and error cost caused by repeated collision with the interference
signal can be reduced, and the interference channel can be rapidly detected and avoided; by monitoring the PDR indexes of the channels in real time, the channels with relatively poor performance are eliminated, so that the BLE is ensured to preferentially use the channels with relatively good performance in the communication process, and the
communication quality is improved.
