Abstract
The present invention is to provide a wireless communication system that is capable of preventing occurrence of radio interference caused by radio wave used by a radio wave generator without requiring any improvement of existing wireless devices. The wireless communication system of the present invention includes: a radio wave generator () that uses at least a radio wave in a frequency band that overlaps a frequency band used by a wireless standard; and wireless devices (AP, STA) each of which uses a radio wave conforming to the wireless standard. The radio wave generator () transmits a dummy frame conforming to the wireless standard to the wireless devices near the radio wave generator () before generating the radio wave in the same frequency band as the frequency band used by the wireless standard. When the wireless devices (AP, STA) receive the dummy frame, the wireless devices (AP, STA) control themselves to stop using the radio wave in the frequency band that has radio interference caused by the radio wave generated from the radio wave generator ().
