This is old news to anyone living here and paying attention. I've been tracking suspicious cell sites for the past three years in my DC metro neighborhood with an old Android phone and some prosumer software.

Some of the sites are mobile, but most of the ones I found were stationarity, and could be easily identified once you know what to look for. I'm pretty sure some of them are seriously degrading cell data/vocie quality.

I stopped once I realized there was nothing you could do once you found them. there are only a couple of options for who is deploying them none of which I want to screw with.
