To stably perform high-capacity and high-speed data transmission over a wide underwater range such as under the sea.SOLUTION: A base station includes a first antenna that transmits and receives signals for communication with a mobile communication body that can move underwater, an acquisition unit that acquires the communication status with the mobile communication body based on the signals, and a determination unit that determines a communication mode with the mobile communication body based on the communication status so that a frequency band used in the current communication is switched to a low-frequency or high-frequency side.SELECTED DRAWING: Figure 6

    【課題】海中等の水中の広い範囲において大容量かつ高速のデータ通信を安定的に行う。【解決手段】基地局は、水中を移動可能な移動通信体との間で通信に係る信号の送受信を行う第1アンテナと、信号に基づく移動通信体との間の通信状況を取得する取得部と、通信状況に基づいて、現在の通信での使用周波数帯を低周波側又は高周波側に切り換えるように移動通信体との間の通信モードを決定する決定部と、を備える。【選択図】図6
