Abstract

A multiple access point system includes a wireless network including a first channel and a second channel. The system further includes a first access point and a second access point co-located within a single physical location environment, a wireless backhaul connecting the first and second access points to the wireless network, and a processor configured to (i) assign the first channel as a primary channel of the first access point and the second channel as a primary channel of the second access point, and (ii) assign the first channel as a secondary channel of the second access point and the second channel as a secondary channel of the second access point. The primary channel of the first access point does not overlap with the primary channel of the second access point, and the secondary channel of the second access point overlaps with the first access point.

First claim

The invention claimed is:

1. A multiple access point system, comprising:
a wireless network including a first channel and a second channel;
a first access point adjacent a second access point co-located within a single physical location environment;
a wireless backhaul connecting the first and second access points to the wireless network; and
a processor configured to (i) assign the first channel as a primary channel of the first access point and the second channel as a primary channel of the second access point, (ii) assign the first channel as a secondary channel of the second access point, and (iii) assign the second channel as a secondary channel of the second access point,
wherein the processor is configured to assign the first and second channels considering that:
the primary channel of the first access point does not overlap with the primary channel of the second access point;
the secondary channel of the second access point overlaps with the first access point; and
the secondary channel of the first access point is shared with the primary channel of the adjacent second access point,
wherein the processor further comprises a component of a modem termination system external to the single physical location environment, wherein at least one of the first access point and the second access point are in operable communication with the modem termination system.

2. The system of claim 1 , wherein the processor comprises a component of at least one of the first access point and the second access point.

3. The system of claim 1 , wherein the processor comprises a component of at least one of a router, a modem, and a gateway located at the single physical location environment.

4. The system of claim 1 , wherein the at least one of the first access point and the second access point is configured to communicate directly with the modem termination system.

5. The system of claim 1 , wherein the at least one of the first access point and the second access point is configured to communicate indirectly with the modem termination system through at least one of a router, a modem, and a gateway located at the single physical location environment.

6. The system of claim 1 , further comprising a third access point and a fourth access point co-located within the single physical location environment and connected to the wireless network through the wireless backhaul, wherein the third access point is adjacent the first access point, and wherein the fourth access point is adjacent the second access point.

7. The system of claim 6 , wherein the processor is further configured to assign the first access point and the third access point into a first channel group, and the second access point and the fourth access point into a second channel group.

8. The system of claim 7 , wherein the processor is further configured to assign (i) the first channel group to a first physical region of the single physical location environment, and (ii) the second channel group to a second physical region of the single physical location environment different from the first physical region.

9. The system of claim 8 , wherein the single physical location environment is a multiple-floor dwelling, and wherein the first and second physical regions are separate floors of the multiple-floor dwelling.

10. The system of claim 7 , wherein the third access point includes a third primary channel and a third secondary channel, wherein the fourth access point includes a fourth primary channel and a fourth secondary channel, wherein the third primary channel does not overlap with the primary channel of the first access point, and wherein the fourth primary channel does not overlap with the primary channel of the second access point.

11. The system of claim 10 , wherein the third secondary channel overlaps with the first access point, wherein the wireless network further includes a third channel, and wherein the processor is further configured to assign the second channel as the third primary channel and the third channel as the third secondary channel.

12. The system of claim 11 , wherein the third secondary channel does not overlap with the second access point.

13. The system of claim 12 , wherein the third secondary channel overlaps with the fourth access point.

14. The system of claim 13 , wherein the processor is further configured to assign the third channel as the fourth primary channel and the second channel as the fourth secondary channel.

15. The system of claim 14 , further comprising a fifth access point and a sixth access point co-located within the single physical location environment and connected to the wireless network through the wireless backhaul, wherein the fifth access point is adjacent the third access point, and wherein the sixth access point is adjacent the fourth access point.

16. The system of claim 15 , wherein the processor is further configured to assign the fifth access point into the first channel group, and the sixth access point into the second channel group.

17. The system of claim 16 , wherein the fifth access point includes a fifth primary channel and a fifth secondary channel, wherein the sixth access point includes a sixth primary channel and a sixth secondary channel, wherein the fifth primary channel does not overlap with the primary channel of the third access point, and wherein the sixth primary channel does not overlap with the primary channel of the fourth access point.

18. The system of claim 17 , wherein the fifth secondary channel overlaps with the sixth access point.

19. The system of claim 18 , wherein the processor is further configured to assign (i) the third channel as the fifth primary channel, (ii) the first channel as the fifth secondary channel, (iii) the first channel as the sixth primary channel, (ii) the third channel as the sixth secondary channel.
