A communication system is disclosed including a backbone network, a moving vehicle further including a vehicle selection unit, an array of base stations connected to the backbone network, and a station selection unit provided to the array of base stations. The moving vehicle transmits upstream data to the array of base stations using an upstream signal frequency uniquely allocated to the moving vehicle, the upstream data being addressed to the backbone network. The station selection unit, if the upstream data is received redundantly, discards the redundantly-received upstream data, and transfers the upstream data to the backbone network. The array of base stations transmits downstream data received from the backbone network to the moving vehicle using a downstream signal frequency common to the array of base stations. The vehicle selection unit selects the downstream data addressed to the moving vehicle.
