PROBLEM TO BE SOLVED: To evade the interference of a compound radio device and other radio devices while evading the interference of a wireless LAN device and a feeble radio wave wireless device inside the compound radio device. SOLUTION: The compound radio device 1 performs first wireless communications and second wireless communications within the same channel band. The wireless LAN device 10 performs the first wireless communications using a plurality of channels, and the feeble radio wave wireless device 20 performs the second wireless communications using the plurality of other channels different from the plurality of channels used in the first wireless communication. In this case, when the first wireless communication is stopped, the feeble radio wave wireless device 20 sets a channel frequency to be used in the second wireless communication by the feeble radio wave wireless device 20 within the channel band used in the first wireless communication immediately before the first wireless communication is stopped.
