    Speedtest.net bought a service that was doing this already sort of. I looked just now and I think it’s their “map” option on their mobile app. You need to switch between carriers to see coverage.

    The tech was based off of manual speed tests and a background app that would measure coverage from a phone for a small area, about the size of 3 square acres.
