摘要

A wireless communication apparatus for performing wireless communication using at least one of the first channel having the first frequency band, and the second channel having the second frequency band which is wider than the first frequency band includes channel search means (22) for executing the first channel search for the bandwidth of the first frequency band and the second channel search for the bandwidth of the second frequency band, and thereby obtaining a search result indicating an idle channel, and determination means (23) for determining a channel to be used on the basis of the search result obtained by the channel search means (22).
