Abstract

Systems and methods are described herein for avoiding interfering with 5GHZ frequency band signals with a peer-to-peer wireless local area network connection. A peer-to-peer client is notified of radar signals in proximity to the client over a master-to-client wireless local area connection with an enterprise access point. If the notification includes a non-interfering radar channel, the peer-to-peer client resets the peer-to-peer channel to the non-interfering radar channel. If the notification does not provide a non-interfering radar channel, the peer-to-peer client resets the peer-to-peer network connection to a non-dynamic frequency selection channel and may disconnect the Wi-Fi connection with the enterprise access point.

First claim

The claimed invention is:

1. A method comprising:
monitoring messages from an access point on a first communications channel, the first communications channel associated with a master-to-client wireless local area network connection and a peer-to-peer wireless local area network connection, wherein the messages comprise an indication of at least one operation of the master-to-client wireless local area network connection and the peer-to-peer wireless local area network connection;
detecting a channel change message from the access point using the master-to-client wireless local area network connection on the first communications channel using a computer processor, wherein the channel change message comprises: an indication of an interfering signal of a non-802.11 device on the first communications channel;
reestablishing the peer-to-peer wireless local area network connection on a second communications channel by scanning a spectrum of communications channels to locate the second communications channel that is free of the interfering signal of the non-802.11 device based at least in part on receiving the channel change message using the master-to-client wireless local area network connection; and
switching the master-to-client wireless local area network connection to the second communications channel or disabling the master-to-client wireless local area network connection based at least in part on receiving the channel change message over the master-to-client wireless local area network connection, wherein the peer-to-peer wireless local area network connection remains active whether the master-to-client wireless local area network connection is active or disabled.

2. The method of claim 1 , wherein reestablishing the peer-to-peer wireless local area network connection comprises:
resetting the peer-to-peer wireless local area network connection on the second communications channel.

3. The method of claim 1 , wherein the channel change message comprises a notification of the second communications channel and wherein reestablishing the peer-to-peer wireless local area network connection comprises resetting the peer-to-peer wireless local area network connection on the second communications channel that is provided in the channel change message.

4. The method of claim 1 , wherein the second communications channel comprises a frequency on one or more allowed channels on a 5 GHz unlicensed spectrum.

5. The method of claim 1 , wherein the interfering signal is from a radar system.

6. The method of claim 1 , wherein the interfering signal is from a satellite system.

7. The method of claim 1 , further comprising switching the master-to-client wireless local area network connection to the second communications channel based at least in part on receiving the channel change message.

8. The method of claim 1 , further comprising disabling the master-to-client wireless local area network connection.

9. The method of claim 1 , wherein the master-to-client wireless local area network connection comprises an access point that provides the channel change message.

10. One or more tangible computer-readable storage devices comprising computer-executable instructions operable to, when executed by at least one processor, enable the at least one processor to implement a method comprising:
monitoring messages from an access point on a first communications channel, the first communications channel associated with a master-to-client wireless local area network connection and a peer-to-peer wireless local area network connection, wherein the messages comprise an indication of at least one operation of the master-to-client wireless local area network connection or the peer-to-peer wireless local area network connection;
detecting a channel change message from the access point using the master-to-client wireless local area network connection on the first communications channel using a computer processor, wherein the channel change message comprises: an indication of an interfering signal of a non-802.11 device on the first communications channel;
reestablishing the peer-to-peer wireless local area network connection on the second communications channel by scanning a spectrum of communications channels to identify the second communications channel that is free of the interfering signal of the non-802.11 device based at least in part on receiving the channel change message using the master-to-client wireless local area network connection; and
switching the master-to-client wireless local area network connection to the second communications channel or disabling the master-to-client wireless local area network connection based at least in part on receiving the channel change message over the master-to-client wireless local area network connection, wherein the peer-to-peer wireless local area network connection remains active whether the master-to-client wireless local area network connection is active or disabled.

11. The one or more tangible computer-readable storage devices of claim 10 , wherein reestablishing the peer-to-peer wireless local area network connection comprises:
resetting the peer-to-peer wireless local area network connection on the second communications channel.

12. The one or more tangible computer-readable storage devices of claim 10 , wherein the channel change message comprises a notification of the second communications channel, and wherein reestablishing the peer-to-peer wireless local area network connection comprises resetting the peer-to-peer wireless local area network connection on the second communications channel that is provided in the channel change message.

13. The one or more tangible computer-readable storage devices of claim 10 , wherein the second communications channel comprises a channel on a 5 GHz frequency band.

14. The one or more tangible computer-readable storage devices of claim 10 , wherein the interfering signal is from a radar system.

15. The one or more tangible computer-readable storage devices of claim 10 , wherein the interfering signal is from a satellite system.

16. The one or more tangible computer-readable storage devices of claim 10 , further comprising switching the master-to-client wireless local area network connection to the second communications channel based at least in part on receiving the channel change message.

17. The one or more tangible computer-readable storage devices of claim 10 , further comprising disabling the master-to-client wireless local area network connection.

18. The one or more tangible computer-readable storage devices of claim 10 , wherein the master-to-client wireless local area network connection comprises an access point that provides the channel change message.

19. A device comprising:
a wireless communications module comprising a wireless transceiver;
at least one memory storing computer-executable instructions; and
at least one processor, wherein the at least one processor is configured to access the at least one memory and to execute the computer-executable instructions to:
instruct the wireless communications module to send and receive wireless electronic communications from an access point over a first communications channel associated with a master-to-client wireless local area network connection and a peer-to-peer wireless local area network connection, wherein the wireless electronic communications comprise messages comprising an indication of at least one operation of the master-to-client wireless local area network connection or the peer-to-peer wireless local area ne
