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.

Claims

1. A method of establishing communication between a computer premise equipment (CPE) unit and a plurality of base station units, comprising the steps of:

user-installing said CPE unit to a host located within a premise, wherein said CPE unit is completely contained within said premise;

automatically registering with one of said plurality of base station units by radio frequency communication upon said CPE unit being user-installed.

2. The method of claim 1 wherein said step of registering is based upon a quality of signal emitted by said base station unit.

3. The method of claim 1 further comprising said one base station unit determining whether the registration of said CPE unit is allows with said one base station unit.

4. The method of claim 3 further comprising said one base station unit denying or acknowledging said CPE unit.

5. The method of claim 1 wherein said CPE unit is connected to a plurality of hosts and wherein upon said CPE unit registering with one of said plurality of base station units, said CPE unit passes the addresses of those hosts connected to said CPE unit to said one base station.

6. The method of claim 5 wherein said host is selected from a group consisting of:

a single-host computer and a network of a plurality of host computers.

7. The method of claim 6 wherein said CPE unit is connected to said plurality of hosts via an Ethernet connection.

8. The method of claim 1 wherein said radio frequency communication is under 10 GHz.
