To provide stable mobile radio communication without omission by receiving with an antenna on a rear side in a travel direction.SOLUTION: Two or more antennas 20 are installed facing a travel direction on a mobile body 2 for the travelling mobile body 2 to wirelessly communicate with an outside ground radio station 3. A current travelling position is acquired. Based on the acquired current travelling position and the position of the ground radio station 3, an antenna 20 that transmits and receives transmission information to/from a terminal device 6 is selected.SELECTED DRAWING: Figure 2
【課題】走行方向の後方側のアンテナにおいて受信することで漏れなく安定的な移動体無線通信を実現する。【解決手段】走行中の移動体2が外部の地上無線局3との間で無線通信する上で、移動体2上に走行方向に向けて2以上の配設されたアンテナ20を配設し、現在の走行位置を取得し、取得した現在の走行位置と地上無線局3の位置とに基づいて、端末装置6に対して伝送情報を送受信するアンテナ20を選択することを特徴とする。【選択図】図2
