Abstract

The present disclosure relates to computer-implemented systems and methods for wireless communication in radar transmission channels. The method may include receiving, by a first computer comprising one or more processors from a second computer, a request to initiate wireless communication, the first computer in communication with a wireless access point. Additionally, the method may include determining, by the first computer, that the wireless access point is communicating in a radar transmission channel. Further still, the method may include establishing wireless peer-to-peer communication between the first computer and the second computer in the radar transmission channel.

Claims

1. A method, comprising:

receiving, by a first computer comprising one or more processors from a second computer, a request to initiate wireless communication, the first computer in communication with a wireless access point;

storing, by the first computer, a first wireless access point identifier associated with the wireless access point;

determining, by the first computer, that the wireless access point is communicating in a radar transmission channel;

receiving, by the first computer, a second wireless access point identifier associated with the second computer;

determining, by the first computer, whether the first wireless access point identifier matches the second wireless access point identifier; and

establishing, by the first computer based at least in part upon a positive determination that the first wireless access point identifier matches the second wireless access point identifier, wireless peer-to-peer communication between the first computer and the second computer in the radar transmission channel.

2. The method of claim 1, further comprising receiving, from the wireless access point, instructions to vacate the radar transmission channel.

3. The method of claim 2, further comprising re-establishing, by the first computer in response to the instructions from the wireless access point, the wireless communication with the second computer in a non-radar transmission channel.

4. The method of claim 1, wherein the radar transmission channel is a dynamic frequency selection channel.

5. The method of claim 1, wherein establishing the wireless peer-to-peer communication between the first computer and the second computer comprises establishing a Wi-Fi Direct connection.

6. A device, comprising:

a transceiver;

at least one processor; and

at least one memory storing computer-executable instructions, that when executed by the at least one processor, causes the at least one processor to;

establish communication with a wireless access point;

receive, by the transceiver from a second device, discovery information associated with the second device;

determine, based at least in part on the discovery information, whether the second device is in communication with the wireless access point;

determine whether the wireless access point is operating in a radar transmission channel; and

establish, upon a positive determination that the second device is in communication with the wireless access point and upon a positive determination that the wireless access point is operating in a radar transmission channel, a wireless peer-to-peer connection with the second device in the radar transmission channel.

7. The device of claim 6, wherein the computer-executable instructions to determine whether the second device is in communication with the wireless access point further comprises computer-executable instructions that cause the at least one processor to:

determine a first access point identifier associated with the wireless access point;

receive, by the transceiver from the second device, a second access point identifier; and

determine whether the first access point identifier matches the second access point identifier.

8. The device of claim 7, wherein the second access point identifier is included in the discovery information received from the second device.

9. The device of claim 6, wherein the computer-executable instructions further cause the at least one processor to:

determine, upon a negative determination that the second device is not in communication with the wireless access point, whether the second device is able to detect the presence of the wireless access point.

10. The device of claim 9, wherein the computer-executable instructions further cause the at least one processor to:

establish, based at least in part upon a positive determination that the second device is able to detect the presence of the wireless access point and upon a positive determination that the wireless access point is operating in a radar transmission channel, a wireless peer-to-peer connection with the second device in the radar transmission channel; and

designate the device as a group owner of the wireless peer-to-peer connection.

11. The device of claim 6, wherein the computer-executable instructions further cause the at least one processor to:

receive, from the wireless access point, instructions to vacate the radar transmission channel.

12. The device of claim 11, wherein the computer-executable instructions further cause the at least one processor to:

re-establish, in response to the instructions from the wireless access point, the wireless peer-to-peer communication with the second device in a non-radar transmission channel.

13. The device of claim 6, wherein the radar transmission channel is a dynamic frequency selection channel.

14. The device of claim 6, wherein the wireless peer-to-peer connection comprises a Wi-Fi Direct connection.

15. A non-transitory computer-readable medium comprising instructions, that when executed by at least one processor, cause the at least one processor to:

establish communication with a wireless access point;

receive, from a second device, discovery information associated with the second device;

determine, based at least in part on the discovery information, whether the second device is in communication with the wireless access point;

determine whether the wireless access point is operating in a radar transmission channel; and

establish, upon a positive determination that the second device is in communication with the wireless access point and upon a positive determination that the wireless access point is operating in a radar transmission channel, a wireless peer-to-peer connection with the second device in the radar transmission channel.

16. The computer-readable medium of claim 15, wherein the computer-executable instructions to determine whether the second device is in communication with the wireless access point further comprises computer-executable instructions that cause the at least one processor to:

determine a first access point identifier associated with the wireless access point;

receive, by the transceiver from the second device, a second access point identifier; and

determine whether the first access point identifier matches the second access point identifier.

17. The computer-readable medium of claim 16, wherein the second access point identifier is included in the discovery information received from the second device.

18. The computer-readable medium of claim 15, wherein the instructions further cause the at least one processor to:

determine, upon a negative determination that the second device is not in communication with the wireless access point, whether the second device is able to detect the presence of the wireless access point.

19. The computer-readable medium of claim 18, wherein the instructions further cause the at least one processor to:

establish, based at least in part upon a positive determination that the second device is able to detect the presence of the wireless access point and upon a positive determination that the wireless access point is operating in a radar transmission channel, a wireless peer-to-peer connection with the second device in the radar transmission channel.

20. The computer-readable medium of claim 15, wherein the instructions further cause the at least one processor to:

receive, from the wireless access point, instructions to vacate the radar transmission channel.

21. The computer-readable medium of claim 20, wherein the instructions further cause the at least one processor to:

re-establish, in response to the instructions from the wireless access point, the wireless peer-to-peer communication with the second device in a non-radar transmission channel.

22. The computer-readable medium of claim 15, wherein the radar transmission channel is a dynamic frequency selection channel.
