Hello DFS folks, now that DFS support is emerging in linux-wireless, we have quite some testing ahead. Testing DFS towards certification at physical layer requires laboratory equipment that is very expensive (often going into the 6-digit US$ range) and makes it non-affordable for independent developers or smaller companies. We evaluated a SDR (software defined radio) approach and found it to be a very well usable alternative for exorbitant dedicated radar generating equipment. Our approach uses an Ettus research USRP N200 device to continuously stream radar patterns as waveforms in the time domain to be radiated to the attached wiphy. The SW that abstracts the SDR and the generation of samples for a given radar pattern is open sourced and available at [1]. With the 'USRP-Radar-Relay' SW and SDR you can have a highly customizable and flexible radar generating device for less than 2k$ - a definitely lower barrier to decentralize DFS testing.
