Abstract
A wireless communication device that includes a wireless communication unit that performs a wireless communication in a first mode using a first frequency band serving as a first communication channel, and performs the wireless communication in a second mode using a second frequency band including the first communication channel and a second communication channel that is adjacent to the first communication channel. Also included is a detection unit that monitors each of the first frequency band and the second frequency band, outputs a first detection signal when an interference signal is detected in the first frequency band and outputs a second detection signal when the interference signal is detected in the second frequency band. Further included is a determination unit that determines whether the interference signal is in the first communication channel or in the second communication channel based on the first and second detection signals.
