If these are smaller hobby drones and they say they use mobile phone detection, that can get the distance from a cellular site to a phone and by using two or three sites can get a very precise location but not being able to do distance checking on passive WiFi listening and probably only have one single device doing it, how can they track a hobby drone?
Those bigger drones being reported being used, and looking at the Ukraine/Russian drones that can fly many miles, what kind of system must they be using to get that kind of range, both for control and get a video signal back home?
