A wireless communication system comprises a plurality of wireless communication apparatus, a plurality of sub-racks, and a rack. The wireless communication apparatus comprises a demultiplexing circuit, a cable to be connected to the demultiplexing circuit, a waveguide interface to be connected to the cable, and a waveguide to connect the waveguide interface and the antenna. A plurality of sub-racks for each housing the wireless communication apparatus to be connected to an antenna are installed in the rack. Among a plurality of the wireless communication apparatus which are different from one another, a pair of the waveguide interface and waveguide is disposed at a different position from other pair/pairs of waveguide interface and waveguide on a predetermined projectional plane. The waveguide assigned to each of the wireless communication apparatus extends along an outside of the sub-rack.
