Zusammenfassung:To establish a plurality of wireless communications of different frequencies simultaneously without interference.SOLUTION: A wireless communication apparatus 1 has two high-frequency switches IC 81, 82 inserted between a power amplifier 50 and a duplexer 60 for an LTE (B18) transmission system. Between the high-frequency switches IC81, 82, a passing system P which passes through a high-frequency removal apparatus 70 that allows only 800 MHz to pass and a non-passing system Q that does not pass through the high-frequency removal apparatus 70 are provided. When the LTE and WLAN are simultaneously used, the LTE uses the non-passing system Q for transmission first. When a communication control unit 30 detects deterioration of throughput of the WLAN, the LTE uses the passing system P for the transmission. After that, when the throughput of the WLAN is improved or WLAN is not used for communication, the LTE (B18) uses the non-passing system Q for the transmission. Accordingly, simultaneous operation of the LTE (B18) and WLAN (2.4GHz) can be implemented without interference.SELECTED DRAWING: Figure 1 【課題】干渉することなく、異なる周波数による複数の無線通信を同時に行う。【解決手段】無線通信装置1はLTE(B18)の送信系のパワーアンプ50とデュープレクサ60の間に、2つの高周波スイッチIC81、82を挿入する。また、高周波スイッチIC81、82の間に、800MHzのみを通す高周波除去装置70を通る通過系Pと、高周波除去装置70を通らない不通系Qを設ける。LTEとWLANを同時使用のとき、最初はLTEは不通系Qで送信し、WLANのスループットの劣化を通信制御部30が検出した際には、LTEの送信を通過系Pでの送信に切替える。その後、WLANのスループットが改善された場合や、WLANの通信がない場合に、LTE(B18)は不通系Qに切替えて送信する。本実施形態によれば、LTE(B18)とWLAN(2.4GHz)の同時動作を干渉なしに実現することができる。【選択図】図1
