ABSTRACT:
A wireless communication device includes: a wireless communication unit that is configured to: perform a wireless communication in a first mode using a first frequency band serving as a first communication channel; and perform 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; a detection unit that is configured to: monitor each of the first frequency band and the second frequency band; output a first detection signal when an interference signal is detected in the first frequency band; and output a second detection signal when the interference signal is detected in the second frequency band; and 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.
