Abstract

A wireless communication network is provided that includes a plurality of communication cells each defined by at least one communication coverage area and a plurality of access points each corresponding to a different one of the plurality of communication cells. Each access point is configured to communicate on a first frequency with at least one of (i) a subscriber in the at least one communication coverage area in a first communication cell and (ii) a subscriber in a second communication cell. Each access point is further configured to communicate on a second frequency with an access point in a third communication cell.

Claims

1. A wireless communications network using a common wireless communications protocol including a media access layer having a media access control (MAC) frame structure comprising first and second MAC frame sections, the wireless communications network comprising:

a plurality of communications cells configured to use the common wireless communications protocol and comprising at least first, second, and third communications cells;

the first, second, and third communications cells comprising first, second, and third access points, respectively;

the first access point being configured to communicate, using the common wireless communications protocol, on a first frequency, during the first MAC frame section, with a mobile device within a respective wireless communication coverage area of the first communications cell, the first access point also being configured to communicate, using the common wireless communications protocol, on the first frequency with the second access point;

the third access point being configured to communicate, using the common wireless communications protocol, on a second frequency, during the second MAC frame section, with the first access point and a mobile device within a respective wireless communications coverage area of the third communications cell.

2. A wireless communication network in accordance with claim 1, wherein the MAC frame structure comprises a time division duplexing (TDD) frame structure;

and wherein the first and second MAC frame sections comprise first and second half-frames of the TDD frame structure.

3. A wireless communication network in accordance with claim 1, wherein the first access point communicates outbound communications on the first frequency;

and wherein the first access point receives inbound communications on the second frequency.

4. A wireless communication network in accordance with claim 1, wherein the first, second, and third access points are configured to dynamically configure the first and second frequencies based upon at least one of an access point failure, bandwidth usage, communication traffic flow, and communication priority.

5. A method of operating wireless communication network including a plurality of communications cells configured to use a common wireless communications protocol comprising at least first, second, and third communications cells, the first, second, and third communications cells comprising first, second, and third access points, respectively, the common wireless communications protocol including a media access layer having a media access control (MAC) frame structure comprising first and second MAC frame sections, the method comprising:

configuring the first access point to communicate, using the common wireless communications protocol, on a first frequency during the first MAC frame section, and on a second frequency during the second MAC frame section, with at least one of a mobile device within a respective wireless communication coverage area of the first communications cell and the second access point;

configuring the third access point to communicate, using the common wireless communications protocol, on the first frequency during the first MAC frame section, and on the second frequency during the second MAC frame section, with the first access point and a mobile device within a respective wireless communications coverage area of the third communications cell.

6. A method in accordance with claim 5, wherein the MAC frame structure comprises a time division duplexing (TDD) frame structure;

and wherein the first and second MAC frame sections comprise first and second half-frames of the TDD frame structure.

7. A method in accordance with claim 5, wherein the first access point is configured to communicate outbound communications on the first frequency;

and

wherein the first access point is configured to receive inbound communications on the second frequency.

8. A wireless communications network using a common wireless communications protocol including a media access layer having a media access control (MAC) frame structure with first and second MAC frame sections, the wireless communications network comprising:

a plurality of communications cells configured to use the common wireless communications protocol and comprising at least first, second, and third communications cells;

the first, second, and third communications cells comprising first, second, and third access points, respectively;

the first access point being configured to communicate, using the common wireless communications protocol, on a first frequency, during the first MAC frame section, with at least one of a mobile device within a respective wireless communication coverage area of the first communications cell and the second access point;

the third access point being configured to communicate, using the common wireless communications protocol, on a second frequency, during the second MAC frame section, with the first access point and a mobile device within a respective wireless communications coverage area of the third communications cell.

9. A wireless communication network in accordance with claim 8, wherein the MAC frame structure comprises a time division duplexing (TDD) frame structure;

and wherein the first and second MAC frame sections comprise first and second half-frames of the TDD frame structure.

10. A method of operating wireless communication network including a plurality of communications cells configured to use a common wireless communications protocol including a media access layer having a media access control (MAC) frame structure with first and second MAC frame sections, the wireless communication network comprising at least first, second, and third communications cells, the first, second, and third communications cells comprising first, second, and third access points, respectively, the method comprising:

configuring the first access point to communicate, using the common wireless communications protocol, on a first frequency, during the first MAC frame section, with at least one of a mobile device within a respective wireless communication coverage area of the first communications cell and the second access point;

configuring the third access point to communicate, using the common wireless communications protocol, on a second frequency, during the second MAC frame section, with the first access point and a mobile device within a respective wireless communications coverage area of the third communications cell.

11. A method in accordance with claim 10, wherein the MAC frame structure comprises a time division duplexing (TDD) frame structure;

and wherein the first and second MAC frame sections comprise first and second half-frames of the TDD frame structure.
