Abstract

An integrated wireless network comprising a wireless public network and a wireless local area network. The wireless public network comprises a plurality of base stations for communicating with mobile stations in the wireless public network. Each base station communicates with mobile stations up to several miles away. The wireless local area network comprises access points for communicating with selected mobile stations located in the wireless local area network. An access point comprises a first transceiver that communicates with selected mobile stations within a short distance of the access point, a second transceiver that communicates with a first base station of the wireless public network; and 3) interconnection circuitry for transferring data traffic between the first transceiver and the second transceiver, such that the access point enables the selected mobile stations to communicate with the first base station via the access point.

4. The access point as set forth in claim 3 wherein said second transceiver is configured for receiving from said first transceiver data traffic received from at least two mobile stations and transmitting said data traffic received from said at least two mobile stations to said first base station in a single channel using said CDMA2000 wireless protocol.

5. The access point as set forth in claim 1 wherein said first transceiver is configured for communicating with said selected ones of said mobile stations within 500 feet of said access point.

6. The access point as set forth in claim 1 further comprising an access point-to-access point (AP-AP) interface configured for transmitting to a second access point first data received from a first mobile station of said selected ones of said mobile stations by said first transceiver, wherein said first data is directed to a second mobile station in communication with said second access point.

7. The access point as set forth in claim 6 wherein said AP-AP interface is further configured for receiving second data from said second access point and transferring said second data to said first transceiver for subsequent transmission to said first selected mobile station.

8. The access point as set forth in claim 7 wherein said AP-AP interface communicates with said second access point via a wireline link.

9. The access point as set forth in claim 7 wherein said AP-AP interface communicates with said second access point via a wireless link.

10. An integrated wireless network comprising:
