PROBLEM TO BE SOLVED: To provide a radio communication system capable of stably performing radio communication between a train and the ground without incurring facility cost.SOLUTION: The radio communication system includes: a first tag which is installed on the ground on an outer side of a rail track on which a train runs and which is driven with electric power received via radio; a second tag which is installed at a position higher than the first tag and on the outer side of a side face of the train extending in a traveling direction and is driven with electric power received via radio; a radio communication unit which is installed on the train and performs radio communication with the first tag and the second tag; and an antenna which is installed on the train and has radio wave gain in directions of the first tag and the second tag.SELECTED DRAWING: Figure 1

    【課題】設備コストをかけることなく、列車と地上との間で安定に無線通信を行えるようにする。【解決手段】無線通信システムは、列車が走行する軌道よりも外側の地面上に設置され、無線で受信した電力にて駆動される第1のタグと、走行方向に延びる列車の側面よりも外側で、かつ第1のタグよりも上方に設置され、無線で受信した電力にて駆動される第2のタグと、列車に設置され、第1のタグおよび第2のタグとの間で無線通信を行う無線通信部と、列車に設置され、第1のタグおよび第2のタグの方向への電波利得を有するアンテナと、を備える。【選択図】図1
