Abstract
The present invention relates generally to wireless transceivers, and more particularly but not exclusively to radar detection and avoidance methodologies for wireless devices including transceivers. In one or more implementations, a method for detecting radar operating in the unlicensed 5.25-5.35 and 5.47-10.725 GHz radio bands, using wireless devices, such as WiFi AP, are provided. A WiFi AP is used to automatically detect the presence of radar on all channels in these bands, alert all of its clients, and move to another channel that is known to be devoid of radar using one or more implementations.

22. A wireless access device on a communication network capable of detecting radar signals and automatically notifying client devices in communication with the device to one or more of changing communication channel, delaying communication and ceasing communication, having an instantiable computer program product for detecting and avoiding one or more radar signals and communicating information regarding detected radar signals stored on a data storage device accessible by the data system, comprising a computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions including:
- a first executable portion having instructions being capable of;
receiving one or more radar signals, filtering received one or more radar signals, identifying a status of the filtered one or more radar signals as being false or true, notifying one or more client devices on the communication network as to a status of the identified one or more radar signals, and automatically communicating with one or more client devices. - View Dependent Claims (23, 24, 25)
