Wireless communication system

摘要

A SW ( 70 ) receives an Ethernet(R) signal from an outside of areas E and F. The SW ( 70 ) selects and outputs the obtained Ethernet(R) signal to any one of APs ( 91 a to 91 e) in accordance with a network structure managed by the SW ( 70 ). The AP ( 91 a to 91 e) converts the Ethernet(R) signal to an electrical signal type wireless LAN signal, which is in turn output to a main station ( 10 ). The main station ( 10 ) frequency-multiplexes the signal output from each of the APs ( 91 a to 91 e), and converts the signal to an optical signal, which is in turn output to sub-stations ( 20 a and 20 b) The sub-station ( 20 a and 20 b) transmits the signal transmitted from the main station ( 10 ) to a terminal in the form of a wireless radio wave. Thereby, when a plurality of communication areas are present, the accommodation capacity of an AP can be effectively utilized in each communication area.
