PROBLEM TO BE SOLVED: To improve the avoidance capability of radio wave interference.SOLUTION: A wireless LAN system 1 comprises a base station device 10 and a terminal device 20. The base station device 10 transmits, by radio, bandwidth information indicating bandwidth used in radio communication with the terminal device 20, and performs radio communication with the terminal device 20 after the transmission of the bandwidth information by using the bandwidth indicated by the bandwidth information. The terminal device 20 changes bandwidth used in radio communication with the base station device 10 to the bandwidth indicated by the bandwidth information received by radio from the base station device 10.SELECTED DRAWING: Figure 1 【課題】電波干渉の回避能力の向上を図ること。【解決手段】基地局装置１０と端末装置２０を備える無線ＬＡＮシステム１であって、基地局装置１０は、端末装置２０との間の無線通信に使用する帯域幅を示す帯域幅情報を無線により送信し、帯域幅情報を送信してから以後の端末装置２０との間の無線通信を帯域幅情報で示される帯域幅で行い、端末装置２０は、基地局装置１０から無線により受信した帯域幅情報で示される帯域幅に、基地局装置１０との間の無線通信に使用する帯域幅を変更する。【選択図】図１
