Abstract:
1. A wireless communication device comprising: a first communication device that performs wireless communication by using a first frequency band selected from a plurality of first frequency bands; a second communication device that performs communication by frequency hopping by using a plurality of second frequency bands that overlap on the first frequency bands; a wireless-channel control unit that determines usable frequency bands, which are the second frequency band usable for the frequency hopping, based on communication information of the first frequency bands; and an extended-quality-information acquisition unit that acquires communication quality information of an extended frequency band, which is a frequency band in the first frequency bands and other than the usable frequency bands, as extended communication quality information, after determination of the usable frequency bands by the wireless-channel control unit, wherein the wireless-channel control unit adds frequency bands determined as not being used based on the extended communication quality information, as the usable frequency bands, and the extended-quality-information acquisition unit acquires the extended communication quality information for every constant period determined based on at least one of the extended frequency band and a traffic amount of the second communication device.
