> Where on earth would I even have to go to find a place without there being any 2.4Ghz signal interference?
Unironic answer: most airports. Even small ones will have avionics shops, those avionics shops will have to test Emergency Locator Beacons, and those beacon signals are not meant to escape to the outside world during testing.
Thus, most have Faraday rooms, cages, or just small (2-3 cubic feet) boxes to block signals. I used to work for one of those teeny-tiny companies. Would not recommend working in aviation. That said, knocking on the door and offering to come back with doughnuts if they can help you out when it's not crazy busy, feels like less an insane idea than I'd have expected previously.
