Zusammenfassung:PROBLEM TO BE SOLVED: To ensure stable communication speed in radio communication using a cable type antenna.SOLUTION: A radio communication device 12 is disposed within a platform door G disposed on a platform P in a station. A radio wave shield member 123 serving also as a housing for the platform door G has an opening Oon its underside, and an antenna 122 of the radio communication device 12 transmits and receives radio waves through a narrow region stretching from the opening Oto downward. A cable type antenna 112 connected with an access point is accommodated in a radio wave shield member 113 disposed under the platform P. The radio wave shield member 113 has an opening Oat its upper side, and the cable type antenna 112 transmits and receives radio waves through a narrow region stretching from the opening Oto upward. The radio communication device 12 does not suffer from interference of radio waves transmitted by devices carried around by people passing on the platform P and is able to perform radio communication at stable communication speed.SELECTED DRAWING: Figure 2 【課題】ケーブル型アンテナを用いた無線通信における通信速度の安定を確保する。【解決手段】無線通信装置12は、駅のプラットホームPの上に配置されているホームドアG内に配置されている。ホームドアGの筐体を兼ねる電波遮蔽部材123は、底面に開口部O2を有し、無線通信装置12のアンテナ122は開口部O2から下方に拡がる狭い領域を行き交う電波の送受信を行う。アクセスポイントに接続されたケーブル型アンテナ112は、プラットホームPの下に配置された電波遮蔽部材113内に収容されている。電波遮蔽部材113は上側に開口部O1を有し、ケーブル型アンテナ112は開口部O1から上方に拡がる狭い領域を行き交う電波の送受信を行う。無線通信装置12は、プラットホームPの上を往来する人が携帯する装置が発する電波の干渉を受けることなく、安定した通信速度で無線通信を行うことができる。【選択図】図2
