Abstract
A SW () receives an Ethernet® signal from an outside of areas E and F. The SW () selects and outputs the obtained Ethernet® signal to any one of APs (to) in accordance with a network structure managed by the SW (). The AP (to) converts the Ethernet® signal to an electrical signal type wireless LAN signal, which is in turn output to a main station (). The main station () frequency-multiplexes the signal output from each of the APs (to), and converts the signal to an optical signal, which is in turn output to sub-stations (and). The sub-station (and) transmits the signal transmitted from the main station () 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.
