Abstract

An access point for communicating with mobile stations in an integrated wireless network. The access point comprises a first transceiver for communicating with selected mobile stations within a short distance of the access point and an input/output interface that couples the access point to an external mobile station via a communication bus. The externally coupled mobile station communicates with a first base station in a wireless public network. The access point further comprises a data processor that communicates with the externally coupled mobile station via the input/output interface and interconnection circuitry that transfers data traffic between the first transceiver and the data processor. The access point enables the selected mobile stations to communicate with the first base station via the externally coupled mobile station.

Claims

1. An access point for communicating with mobile stations located in a coverage area of an integrated wireless network, said access point comprising:

a first transceiver configured to communicate with selected ones of said mobile stations within a short distance of said access point;

an input/output interface coupling said access point to an external mobile station via a wireline communication bus, wherein said externally coupled mobile station is configured to communicate wirelessly with a first base station in a wireless public network portion of said integrated wireless network;

a data processor configured to communicate with said externally coupled mobile station via said input/output interface; and

interconnection circuitry configured to transfer data traffic between said first transceiver and said data processor, such that said access point enables said selected mobile stations to communicate with said first base station via said externally coupled mobile station.

2. The access point as set forth in claim 1 wherein said first transceiver communicates with said selected mobile stations using an IEEE 802.11 wireless protocol.

3. The access point as set forth in claim 2 wherein said externally coupled mobile station communicates with said first base station using a CDMA2000 wireless protocol.

4. The access point as set forth in claim 3 wherein said data processor is configured to receive from said first transceiver data traffic received from at least two mobile stations and to transmit said data traffic received from said at least two mobile stations to said externally coupled mobile station for subsequent transmission 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 to communicate with said selected 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 to transmit to a second access point first data received from a first selected mobile station 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 to receive second data from said second access point and to transfer 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:

a wireless public network comprising a plurality of base stations configured to communicate with mobile stations located in a coverage area of said wireless public network, wherein each of said plurality of base stations is configured to communicate with mobile stations up to several miles away, and

a wireless local area network comprising a plurality of access points configured to communicate with selected ones of said mobile stations located in a coverage area of the wireless local area network, a first one of said plurality of access points comprising;

a first transceiver configured to communicate with selected ones of said mobile stations within a short distance of said access point;

an input/output interface coupling said access point to an external mobile station via a wireline communication bus, wherein said externally coupled mobile station is configured to communicate wirelessly with a first base station in a wireless public network portion of said integrated wireless network;

a data processor configured to communicate with said externally coupled mobile station via said input/output interface; and

interconnection circuitry configured to transfer data traffic between said first transceiver and said data processor, such that said access point enables said selected mobile stations to communicate with said first base station via said externally coupled mobile station.

11. The integrated wireless network as set forth in claim 10 wherein said first transceiver communicates with said selected mobile stations using an IEEE 802.11 wireless protocol.

12. The integrated wireless network as set forth in claim 11 wherein said externally coupled mobile station communicates with said first base station using a CDMA2000 wireless protocol.

13. The integrated wireless network as set forth in claim 12 wherein said data processor is configured to receive from said first transceiver data traffic received from at least two mobile stations and to transmit said data traffic received from said at least two mobile stations to said externally coupled mobile station for subsequent transmission to said first base station in a single channel using said CDMA2000 wireless protocol.

14. The integrated wireless network as set forth in claim 10 wherein said first transceiver is configured to communicate with said selected mobile stations within 500 feet of said access point.

15. The integrated wireless network as set forth in claim 10 further comprising an access point-to-access point (AP-AP) interface configured to transmit to a second access point first data received from a, first selected mobile station by said first transceiver, wherein said first data is directed to a second mobile station in communication with said second access point.

16. The integrated wireless network as set forth in claim 15 wherein said AP-AP interface is further configured to receive second data from said second access point and to transfer said second data to said first transceiver for subsequent transmission to said first selected mobile station.

17. The integrated wireless network as set forth in claim 16 wherein said AP-AP interface communicates with said second access point via a wireline link.

18. The integrated wireless network as set forth in claim 17 wherein said AP-AP interface communicates with said second access point via a wireless link.

19. In an integrated wireless network comprising:

1) a wireless public network configured to communicate with mobile stations located in a coverage area of the wireless public network; and

     2) a wireless local area network comprising a plurality of access points configured to communicate with selected ones of the mobile stations located in a coverage area of the wireless local area network, a method of operating a first one of the plurality of access points comprising;

communicating with the selected mobile stations within a short distance of the first access point via a first transceiver;

wirelessly communicating with a first one of the plurality of base stations via an external mobile station coupled to the access point via a wireline communication bus; and

transferring data traffic between the first transceiver and the externally coupled mobile station via the wireline communication bus to thereby enable the selected mobile stations to communicate with the first base station via the first access point.
