Abstract

A communication system includes wireless access points that are distributed along a linear, terrestrial-based communications medium that has an operative interface to the Internet. The wireless access points establish wireless connectivity between end users in residences and businesses to the Internet via the communications medium. The operating channel for each wireless access point is controlled by a spectrum management system to control use of available spectrum in an efficient manner and to minimize interference.

Claims

1. A distributed wireless network for delivering Internet connectivity to geographically diverse wireless subscriber devices, comprising a plurality of wireless access points that operatively connect to the Internet through a terrestrial distribution medium, each wireless access point configured to establish a wireless interface with at least one of the wireless subscriber devices for providing Internet connectivity to the wireless subscriber device, and each wireless access point controlled by a channel allocation engine to operate on a channel selected by the channel allocation engine from an available channel pool associated with the wireless access point using channel selection parameters to minimize interference between the wireless access points and the remote wireless subscriber devices.

2. The distributed wireless network of claim 1, wherein at least one wireless access point is allocated a channel that has a larger bandwidth than other wireless access points.

3. The distributed wireless network of claim 2, wherein a bandwidth of each allocated channel is determined by the channel allocation engine based on service load of the corresponding wireless access point.

4. The distributed wireless network of claim 1, wherein the allocated channel for each wireless access point is changed or renewed over time.

5. The distributed wireless network of claim 1, wherein the channels of the available channel pools are each a whitespace.

6. The distributed wireless network of claim 5, wherein the whitespaces are TV whitespaces.

7. The distributed wireless network of claim 1, wherein each wireless access point receives a channel allocation from the channel allocation engine via the Internet and the terrestrial distribution medium.

8. The distributed wireless network of claim 1, wherein the channels of the available channel pools are derived from licensed spectrum.

9. The distributed wireless network of claim 1, wherein the channel allocation for each wireless access point takes into account communication capabilities of the wireless subscriber device serviced by the wireless access point.

10. The distributed wireless network of claim 1, wherein the distribution medium includes a coaxial cable backbone or fiber optic cable backbone.

11. The distributed wireless network of claim 1, wherein overlapping spectrum is allocated to at least two of the wireless access points.

12. A spectrum management system for a distributed wireless network that delivers Internet connectivity to geographically diverse wireless subscriber devices and that includes a plurality of wireless access points that operatively connect to the Internet through a terrestrial distribution medium, comprising a channel allocation engine configured to allocate operating channels to each of the wireless access points, the allocation including selecting each respective operating channel from an available channel pool associated with the wireless access point using channel selection parameters to minimize interference between the wireless access points and the wireless subscriber devices.

13. The spectrum management system of claim 12, wherein at least one wireless access point is allocated a channel that has a larger bandwidth than other wireless access points.

14. The spectrum management system of claim 13, wherein a bandwidth of each allocated channel is determined by the channel allocation engine based on service load of the corresponding wireless access point.

15. The spectrum management system of claim 12, wherein the allocated channel for each wireless access point is changed or renewed over time.

16. The spectrum management system of claim 12, wherein the channels of the available channel pools are each a whitespace.

17. The spectrum management system of claim 16, wherein the whitespaces are TV whitespaces.

18. The spectrum management system of claim 12, wherein a channel allocation for each wireless access point is delivered from the channel allocation engine via the Internet and the terrestrial distribution medium.

19. The spectrum management system of claim 12, wherein the channels of the available channel pools are derived from licensed spectrum.

20. The spectrum management system of claim 12, wherein the channel allocation for each wireless access point takes into account communication capabilities of the wireless subscriber device serviced by the wireless access point.

21. The spectrum management system of claim 12, wherein the distribution medium includes a coaxial cable backbone or fiber optic cable backbone.

22. The spectrum management system of claim 12, wherein overlapping spectrum is allocated to at least two of the wireless access points.
