Fixed OFDM wireless MAN utilizing CPE having internal antenna
First Claim
1. A wireless communication system, comprising:
- a first transceiver and a second transceiver, wherein said first and second transceivers communicate over a radio frequency air link permitting both uplink transmissions and downlink transmissions, that utilize orthogonal frequency division multiplexing (OFDM) modulation, between said first and second transceivers, and wherein said downlink transmission is framed and said uplink transmission is unframed.

Abstract
A fixed wireless access system generally comprises a consumer premise equipment (CPE) unit, that is connected via an Ethernet interface to a personal computer or local area network, and a base station unit that is connected via an Ethernet interface to a network. As such, the CPE unit is preferably easily user-installed while the base station unit 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.
