Abstract
A fixed wireless access system (10) generally comprises a consumer premise equipment (CPE) unit (14), that is connected via an Ethernet interface (16) to a personal computer or local area network (12), and a base station unit (19) that is connected via an Ethernet interface to a network.
As such, the CPE unit (14) is preferably easily user-installed while the base station unit (19) is preferably tower-mounted within a 1-5 mile range of the CPE unit. Both the CPE
unit and base station unit preferably incorporate an integrated data transceiver/switch that enables a radio frequency air link operating in the 2.5-2.686 GHz range. Orthogonal frequency division multiplexing is used in the uplink and downlink transmissions between CPE
units and base station units.
