The present invention provides a channel selecting method and device, relates to the field of communications, and can dynamically scan, detect, and select a channel, so as to ensure that a selected working channel has higher communication quality; and divides and maps the channel uniformly in a discontinuous band manner, so as to improve the efficiency of scanning and detecting the channel. The method comprises: selecting m channels from a preset channel page; determining, from the m channels, a working channel and a standby channel that meet a preset condition; when n first superframes are sent through the working channel, in an inactive period of each first superframe, scanning the working channel and the standby channel according to a first scanning time, so as to obtain energy levels of n working channels and energy levels of n standby channels; and in an inactive period of the nth first superframe, determining, according to the energy levels of the n working channels and the energy levels of the n standby channels, a working channel for sending a second superframe and a standby channel of the second superframe. |
