Wireless device and communication channel selection method

A wireless device comprising:

• a detecting unit configured to detect, for each communication channel while switching multiple communication channels, interference information indicating whether radio frequency interference from a peripheral wireless device is present;
• a sending unit configured to send, before data is sent and received, to a destination wireless device that is the destination of the data, a packet in which pieces of the interference information detected by the detecting unit are sequentially stored for wireless devices;
• and
• a selecting unit configured to receive the packet, to transfer, when the wireless device does not correspond to the destination wireless device that is the destination of the packet, the packet in which the interference information detected by the detecting unit is additionally stored, and to select, when the wireless device corresponds to the destination wireless device that is the destination of the packet, on the basis of the pieces of the interference information that are sequentially stored in the packet for wireless devices and on the basis of the interference information detected by the detecting unit, the communication channel that is used to send and receive the data from among the multiple communication channels.
