Patent ID: 8311136

Claim:
A radio wave generator, comprising: a radio wave generation control unit that controls generation of a radio wave in the same frequency band that overlaps a frequency band used by a wireless standard; and a dummy frame transmit unit that transmits a dummy frame conforming to the wireless standard, wherein the radio wave generation control unit controls to start transmitting the dummy frame and then to generate the radio wave in the same frequency band that overlaps the frequency band used by the wireless standard sequentially to the dummy frame if the radio wave generator is to generate the radio wave, and wherein the radio wave generation control unit comprises: a control signal transmission unit that transmits a control signal for starting the transmission of the dummy frame to the dummy frame transmit unit before the generation of the radio wave is started; and a respond signal receive unit that receives a respond signal indicating that the transmission of the dummy frame is started from the dummy frame transmit unit, wherein the radio wave generation control unit controls to generate the radio wave when the respond signal receive unit receives the respond signal.
