This is incorrect. Wifi systems that don't comply with DFS show up brightly on the radar display. Here's an example from a real-world system of what a misbehaving 5 GHz AP looks like:

The FCC has a list of WISP companies they've gone after for misconfiguring their wireless equipment:

- CamperBob2 4y agoInteresting, I'm genuinely surprised that's necessary. WiFi looks like white noise, and should be more or less trivial for a radar to reject.
- withinboredom 4y agoIf removing “noise” was trivial, we would all have perfect radios.
- jamiek88 4y agoWhat makes you think that would be trivial?
- CamperBob2 4y agoYears of engineering experience in RF and DSP applications. A radar that can be jammed by a WiFi access point amounts to an HR failure at the company that made it.
- Dylan16807 4y agoIt's not jammed, it's dealing with a high noise floor and a weak signal. You can only do so much to identify your own signal when it's smeared over a trillion water droplets.
- jamiek88 4y agoI think you’ve misunderstood what we are talking about. This isn’t jamming. If it was trivial to identify signals from high noise situations all our radios would be perfect.
