Abstract
A wireless communication apparatus includes a transmission and reception unit, a monitoring unit, and a control unit. The transmission and reception unit transmits and receives a frame to and from a wireless communication terminal. The monitoring unit monitors an interference signal in a first communication channel. The control unit selects a second communication channel and a third communication channel. The second and the third communication channels are different from the first communication channel. The transmission and reception unit transmits an instruction frame to the wireless communication terminal when the monitoring unit detects the interference signal in the first communication channel. The instruction frame includes information on the second and third communication channels and instructs the wireless communication terminal to switch the communication channel from the first communication channel to at least one of the second and third communication channels.
