Systems and methods for coordinated access point channel assignment
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.

8. The system of claim 7 , where the external device is selected from the group consisting of a router, a modem, and a gateway.
9. The system of claim 1 , further comprising a third wireless access point including a fifth wireless interface and a sixth wireless interface, and wherein the controller is further configured to control the first, second, and third wireless access points such that:
a fifth coverage area of the fifth wireless interface does not overlap with either of the first coverage area or the third coverage area; and
a sixth coverage area of the sixth wireless interface overlaps with the fourth coverage area.
10. The system of claim 9 , wherein the controller is further configured to control the first, second, and third wireless access points such that:
each of the third wireless interface and the fifth wireless interface operates on a different respective radio channel; and
each of the third wireless interface and the sixth wireless interface operates on a common radio channel.
11. A method for operating a system including at least (a) a first wireless access point including first and second wireless interfaces operating on different respective radio channels and (b) a second wireless access point including third and fourth wireless interfaces operating on different respective radio channels, the method comprising controlling the first and second wireless access points such that:
a first coverage area of the first wireless interface does not overlap with a third coverage area of the third wireless interface;
a second coverage area of the second wireless interface overlaps with a fourth coverage area of the fourth wireless interface; and
the first wireless access point (a) uses the respective radio channel of the first wireless interface for associating network clients and (b) uses the respective radio channel of the second wireless interface for one or more of detecting a wireless client and monitoring a wireless client.
12. The method of claim 11 , further comprising controlling the first and second wireless access points such that the first wireless interface operates on a first radio channel and the third wireless interface operates on a second radio channel that is different from the first radio channel.
13. The method of claim 12 , further comprising controlling the first and second wireless access points such that the second wireless interface operates on the second radio channel.
14. The method of claim 13 , further comprising controlling the first and second wireless access points such that the fourth wireless interface operates on a third radio channel that is different from each of the first and second radio channels.
15. The method of claim 11 , further comprising transmitting data between the first and second wireless access points using a wireless backhaul channel.
16. The method of claim 11 , wherein:
the system further includes a third wireless access point including a fifth wireless interface and a sixth wireless interface; and
the method further comprises controlling the first, second, and third wireless access points such that:
a fifth coverage area of the fifth wireless interface does not overlap with either of the first coverage area or the third coverage area, and
a sixth coverage area of the sixth wireless interface overlaps with the fourth coverage area.
17. The method of claim 16 , further comprising controlling the first, second, and third wireless access points such that:
each of the third wireless interface and the fifth wireless interface operates on a different respective radio channel; and
each of the third wireless interface and the sixth wireless interface operates on a common radio channel.
