Reply to comment by somerandomii in Researchers create a Drone That Can 'See Through Walls' With Wifi | At the University of Waterloo recently fixed one up with a scanning device that is the definition of invasive. by chrisdh79

Except for the whole drones being controlled by what's basically WiFi, they use 2.4 and 5ghz frequencies for that and it will be actively transmitting.

As I said, I’m not talking about the technology in the article. That’s an entirely different use case.

Also autonomous drones don’t need to emit wifi. But you wouldn’t fly a drone around a building to covertly monitor personnel. Drones aren’t very subtle.
