Abstract

A method in a wireless dock includes querying a first wireless networking database to identify a first set of available channels, querying a second wireless networking database to identify a second set of available channels, and sending location and device attributes. The method also includes receiving a list of permissible frequencies and power levels, sending to a client device at least a portion of the list of the permissible frequencies and the power levels for use of selected channels selected from the first set of the available channels and the second set of the available channels, and communicating with the client device using selected frequencies and power levels selected from the at least the portion of the list of the permissible frequencies and the power levels.

Claims

1. A method in a wireless dock, comprising:

querying a first wireless networking database to identify a first set of available channels;

querying a second wireless networking database to identify a second set of available channels;

sending location and device attributes;

receiving a list of permissible frequencies and power levels;

sending to a client device at least a portion of the list of the permissible frequencies and the power levels for use of selected channels selected from the first set of the available channels and the second set of the available channels; and

communicating with the client device using selected frequencies and power levels selected from the at least the portion of the list of the permissible frequencies and the power levels.

2. The method of claim 1, further comprising:

distributing new client device connection information comprising the selected frequencies and the power levels to other wireless docks.

3. The method of claim 1, further comprising:

performing a wireless dock inter-domain coordination function, wireless communication load balancing, and wireless communication scheduler updates.

4. The method of claim 1, wherein the first wireless networking database is a television white space (TVWS) database, and the first set of available channels is a first set of available TVWS channels.

5. The method of claim 1, wherein the second wireless networking database is a wireless local area network (WLAN) access point (AP) database, and the second set of available channels is a second set of available WLAN AP channels.

6. The method of claim 1, wherein the selected channels comprise at least a portion of the first set of the available channels and at least a portion of the second set of the available channels.

7. The method of claim 1, further comprising:

detecting the location of the client device using geographically diverse sensors, the geographically diverse sensors monitoring wireless networking signals emanating from the client device.

8. An information handling system comprising:

a client device; and

a wireless dock for providing wireless communication with the client device, the wireless dock comprising;

a first wireless networking transceiver;

a second wireless networking transceiver; and

a control circuit, coupled to the first wireless networking transceiver and to the second wireless networking transceiver, the control circuit configured to query a first wireless networking database to identify a first set of available channels, to query a second wireless networking database to identify a second set of available channels, to send location and device attributes, to receive a list of permissible frequencies and power levels, to send to the client device at least a portion of the list of the permissible frequencies and the power levels for use of selected channels selected from the first set of the available channels and the second set of the available channels, and to communicate with the client device via at least one of the first wireless networking transceiver and the second wireless networking transceiver using selected frequencies and power levels selected from the at least the portion of the list of the permissible frequencies and the power levels.

9. The information handling system of claim 8, wherein the control circuit is further configured to distribute new client device connection information comprising the selected frequencies and the power levels to other wireless docks.

10. The information handling system of claim 8, wherein the control circuit is further configured to perform a wireless dock inter-domain coordination function, wireless communication load balancing, and wireless communication scheduler updates.

11. The information handling system of claim 8, wherein the first wireless networking database is a television white space (TVWS) database, and the first set of available channels is a first set of available TVWS channels.

12. The information handling system of claim 8, wherein the second wireless networking database is a wireless local area network (WLAN) access point (AP) database, and the second set of available channels is a second set of available WLAN AP channels.

13. The information handling system of claim 8, wherein the selected channels comprise at least a portion of the first set of the available channels and at least a portion of the second set of the available channels.

14. The information handling system of claim 8, wherein the control circuit is further configured to obtain the location of the client device using geographically diverse sensors, the geographically diverse sensors monitoring wireless networking signals emanating from the client device.

15. A method in a client device, comprising:

querying a database to obtain client device indoor location position information based on wireless networking signals emanating from the client device;

receiving channel availability, power, and coexistence parameters for at least one channel; and

communicating via a wireless dock via the at least one channel based on the client device indoor location position information.

16. The method of claim 15, wherein the at least one channel is a television white space (TVWS) channel.

17. The method of claim 15, further comprising:

transmitting client device multiband capability information, wherein the multiband capability information indicates multiband capability for a 2.4 GHz band, a 5 GHz band, and a 60 GHz band.

18. The method of claim 15, further comprising:

transmitting client device multiband capability information, wherein the multiband capability information indicates multiband capability for a 2.4 GHz band, a 5 GHz band, and a television white space (TVWS) band.

19. The method of claim 15, further comprising:

transmitting client device multiband capability information, wherein the multiband capability information indicates multiband capability for a 2.4 GHz band, a 5 GHz band, a 60 GHz band, and a television white space (TVWS) band.

20. The method of claim 15, further comprising:

switching to communicate via a second wireless dock in response to updated client device indoor location position information.
