Description

電波強度制御部３１は、ＡＰ１０と各ＳＴＡとの間で行われる通信において、ＡＰ１０へ新たなＳＴＡの接続、直前まで通信していたＳＴＡの切断など装置間の通信状態に変化が生じた旨の通知を受信部３０から受けた場合、情報管理部３３の情報管理テーブル３３１からＡＰ１０と各ＳＴＡとの間で行われている通信における現在の最適な送信電波強度範囲値を受信する。 In the communication performed between the AP 10 and each STA, the radio wave intensity control unit 31 indicates that a change has occurred in the communication state between devices, such as connection of a new STA to the AP 10 and disconnection of the STA that was communicating immediately before. when receiving the notification from the receiving unit 30 receives the current optimal transmit radio intensity range values in communication performed between the information management table 331 of the information management section 33 and the AP10 and each STA.
