Abstract

A communication system and a method of communicating backhaul data. The communication system can include a controller. The controller can dynamically select from a plurality of backhaul sites at least a first backhaul site to establish a backhaul communication link with an access point. The controller also can generate a control signal that indicates to the access point to beam steer a backhaul signal to the first backhaul site. The access point can include a phased array that dynamically beam steers the backhaul signal in azimuth and elevation.

Claims

1. A method of communicating backhaul data comprising:

from a plurality of backhaul sites that are each configured to wirelessly communicate with an access point, dynamically selecting a first backhaul site to establish a backhaul communication link with the access point; and

dynamically beam steering backhaul signals communicated between the access point and the backhaul site.

2. The method according to claim 1, wherein dynamically beam steering the backhaul signals comprises beam steering the backhaul signals to at least one directional coordinate selected from the group consisting of an azimuth and an elevation.

3. The method according to claim 1, wherein dynamically selecting the first backhaul site comprises evaluating available bandwidth on each of the plurality of backhaul sites.

4. The method according to claim 1, wherein dynamically selecting the first backhaul site comprises evaluating a temporal traffic pattern of backhaul communications.

5. The method according to claim 1, wherein dynamically selecting the first backhaul site comprises evaluating a geometrical traffic pattern of backhaul communications.

6. The method according to claim 1, wherein dynamically selecting the first backhaul site comprises evaluating a priority level of at least one network node selected from the group consisting of the access point and a communication device.

7. The method according to claim 1, further comprising implementing diversity for the backhaul signals communicated between the access point and the backhaul site.

8. The method according to claim 7, wherein implementing diversity for the backhaul signals comprises implementing at least one diversity scheme selected from the group consisting of polarization diversity and spatial diversity.

9. A communication system comprising:

an access point comprising a phased array that dynamically beam steers backhaul signals;

a plurality of backhaul sites that are each configured to wirelessly communicate with the access point; and

a controller that dynamically selects from the plurality of backhaul sites at least a first backhaul site to establish a backhaul communication link with the access point, and generates a control signal that indicates to the access point to beam steer a backhaul signal to the first backhaul site.

10. The communication system of claim 9, wherein the phased array dynamically steers the backhaul signals to at least one directional coordinate selected from the group consisting of an azimuth and an elevation.

11. The communication system of claim 9, wherein the controller evaluates available bandwidth on each of the plurality of backhaul sites.

12. The communication system of claim 9, wherein the controller evaluates a temporal traffic pattern of backhaul communications.

13. The communication system of claim 9, wherein the controller evaluates a geometrical traffic pattern of backhaul communications.

14. The communication system of claim 9, wherein the controller evaluates a priority level of at least one network node selected from the group consisting of the access point and a communication device.

15. The communication system of claim 9, wherein the access point implements diversity for the backhaul signals communicated between the access point and the backhaul site.

16. The communication system of claim 15, wherein the diversity that is implemented comprises at least one diversity scheme selected from the group consisting of polarization diversity and spatial diversity.

17. A machine readable storage having stored thereon a computer program having a plurality of code sections comprising:

code for dynamically selecting a first backhaul site to establish a backhaul communication link with an access point, the first backhaul site selected from a plurality of backhaul sites that are each configured to wirelessly communicate with the access point; and

code for dynamically beam steering backhaul signals communicated between the access point and the backhaul site.

18. The machine readable storage of claim 17, wherein the code for dynamically beam steering the backhaul signals further comprises code for beam steering the backhaul signals to at least one directional coordinate selected from the group consisting of an azimuth and an elevation.

19. The machine readable storage of claim 17, wherein the code for dynamically selecting the first backhaul site further comprises code for evaluating a temporal traffic pattern of backhaul communications.
