Abstract: PROBLEM TO BE SOLVED: To provide a radio communication system where the problem of cost and coverage and the difficulty of installation are solved by up-converting an information transportation signal into an intermediate frequency, transmitting it on a wire, receiving it and up-converting it into a radio frequency. SOLUTION: A radio communication system 400 is connected to a plurality of radio machine heads 401-1 to 401-6 from a base band unit 403 through one of the wires 402-1 to 402-3 of a pair of stranded wires. The base band unit 403 is formed of block radio machines, it receives an information transportation signal and a control signal from traffic signaling 404, modulates, channel-encodes and multiplexes the signals and transmit them to the wires 402-1 to 402-3. The radio machine heads 401-1 to 401-6 are provided with antennas and are arranged so that a dead area is not caused in coverage, separating desired information transportation signals from a multiplexed intermediate frequency and radiating the signals from the antennas by a desired radio frequency.
