Do Drones emit radio frequencies?

My husband today is putting up a fence on our land and we noticed a neighbour sent a drone over to 'inspect' what he was doing.
Every night for the last few weeks I have been waking up about 3am with the feeling that someone is operating stong wifi. The emf reader shows an increase in radio frequencies (even in my shielded room) and sometimes the magnetic field shoots up to between 18 and 30 v/m and then back down again. I suspected it was some kind of activity going on from neighbours or even army not so far away. Do you think this could be the effect of a drone flying over our property? Do we have any right to stop it? Thanks

Any drone with a camera has WiFi. The signal strength is likely to be high because they can't afford to drop the connection, and they're sending a *lot* of data (continuous HD video).

Check your state's laws about property rights. In some places you can stop a drone flying over your property, but in other places there's not much you can do. You don't have to bring up ES and you probably shouldn't; if your state gives you a say, then just tell your neighbor not to fly over your yard.

Thanks Karl for the information. I'll look into it. Much appreciated

I also has a drone with wifi https://www.extremefliers.com/best-fpv-drones/ DJI FPV, but my drone can't block any waves. Plus, I can't afford to run it over neighbors' houses, I think it's illegal, so I don't think it's your neighbor, especially since blocking everything looks strange.
