Russian forces are using LTE mobile networks and Ukrainian SIM cards to remotely control FPV drones, Serhii Beskrestnov, adviser to Defense Minister Mykhailo Fedorov, said.
For me the question arises: can a cell phone base station measure Doppler shift for an individual client, and switch it off basing on the result?
I believe so. Cell tower triangulation via travel-time and signal strength is an existing, already proven method to get very general location data from cellular devices, just using that over a few samples would get you approximate speed data and likely be sufficient.
