A second RF transceiver(20) is installed inside the train to communicate with one of first RF transceivers in wireless. A high speed roaming controller(30) is connected to the first RF ransceiver inside the station in wire and roams an operation control right to one of the first RF transceivers according to the train passing through a service area.
