Abstract

See full text

The present invention relates to wireless networks and more specifically to systems and methods for selecting available channels free of radar signals from a plurality of 5 GHz radio frequency channels. In one embodiment, the present invention provides a standalone multi-channel DFS master that includes a switch and embedded processor that are programmed to switch a 5 GHz radio transceiver to a first channel of the plurality of 5 GHz radio channels, cause a beacon generator to generate a beacon in the first channel of the plurality of 5 GHz radio channels, cause a radar detector to scan for the radar signal in the first channel of the plurality of 5 GHz radio channel, and then repeat these steps for each of the other channels of the plurality of 5 GHz radio channels during a single beacon transmission duty cycle.
