Abstract

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.

Description

technical field [0001] The present invention relates to a wireless communication system and a wireless communication device, in particular to a wireless communication system and a wireless communication device installed in a station connected by an antenna and a waveguide. Background technique [0002] Generally, a waveguide is used in an antenna-side interface of a microwave band wireless communication device. When a wireless communication device is installed in an office building or a shelter, a waveguide is used to connect the antenna and the wireless communication device. [0003] In the construction of a wireless communication system, cost reduction is increasingly required. In order to achieve this cost reduction, it is necessary to achieve a total cost reduction from system design to equipment installation, maintenance, and operation in addition to the wireless communication device itself. [0004] Image 6 It is a figure for explaining the structure of the wireless...
