Abstract

This application relates to wireless networks and more specifically to systems and methods for determining the location of distributed radar detectors and selecting available channels free of radar signals from a plurality of radio frequency channels. One embodiment includes a cloud DFS super master and a radar detector communicatively coupled to the cloud DFS super master. The cloud DFS super master is programmed to receive the results of the scan for a radar signal from the radar detector and to generate integrated client device geolocation information. The cloud DFS super master is also programmed to determine a location for the radar detector based at least on the integrated client device geolocation information, and determine a radio channel free of the radar signal based at least on the location for the radar detector and the results of the scan for the radar signal.

wherein the cloud DFS super master is programmed to receive the radar detection results of the scan for the radar signal from the radar detector and to receive geolocation information of a client device communicatively coupled to the radar detector, integrate the client device geolocation information with other client device geolocation information pertaining to the client device geolocation information to generate integrated client device geolocation information, determine a location for the radar detector based at least on the integrated client device geolocation information, and determine the radio channel that is free of the radar signal based at least on the location for the radar detector and the radar detection results of the scan for the radar signal.

2. The system of claim 1 wherein the radar detector is programmed to receive the client device geolocation information from the client device and to transfer the client device geolocation information to the cloud DFS super master.

3. The system of claim 2 wherein the radar detector comprises a Bluetooth transceiver and is programmed to receive the client device geolocation information from the client device via the Bluetooth transceiver.

4. The system of claim 1 wherein the cloud DFS super master is programmed to receive the client device geolocation information from the client device.

5. The system of claim 4 wherein the radar detector is programmed to send a location request and a radar detector identifier to the client device that causes the client device to transmit the client device geolocation information and the radar detector identifier to the cloud DFS super master.

6. The system of claim 1 wherein the cloud DFS super master is programmed to receive information from an external data source and is programmed to determine the location of the radar detector based at least on the information from the external data source and the integrated client device geolocation information.

7. The system of claim 6 wherein the external data source is selected from the group consisting of a Geographical Information System (GIS), an Federal Aviation Administration (FAA) radar database, a Department of Defense (DOD) radar database, an Federal Communications Commission (FCC) database, a National Oceanic and Atmospheric Administration (NOAA) database, a crowd-sourced database, and a public/safety database.

8. The system of claim 6 wherein the external data source is a map database and the cloud DFS super master is programmed to determine the location of the radar detector based at least on the integrated client device geolocation information a map received from the map database.

9. The system of claim 1 wherein the radar detector comprises an agility agent.

10. The system of claim 1 wherein the radar detector comprises an access point, LTE small cell or base station, or peer to peer device.

11. A method comprising:
