Abstract:
1. A high-speed wireless LAN system comprising: a mobile station, at least one associated access point and a gateway, said at least one access point and gateway connected by at least one optical fiber; the mobile station for: the at least one associated access point, installed in a plurality of predetermined service areas, for: a semiconductor optical amplifier (SOA) for converting an optical signal corresponding to the data, which is received from the gateway sub-module through the WDM, into a current signal to transmit by wireless the current signal through the UWB antenna, and outputting an optical signal with its gain amplified according to the data signal received through the UWB antenna to transmit the optical signal to the gateway through the WDM; a controller for providing a current to said SOA, wherein in one communication direction the controller provides a current to less than a threshold current while in an opposite communication direction applying a current more than a threshold current; and the gateway, located at a remote place by providing an optical interface between an internal network and an external network, comprising:
