About a year ago, I wrote an article about my attempts to locate T-mobile’s nearby cell sites. I’m still having difficulty. I’ve tried several Android apps that measure signal field strength, with varying success. I’ve had the best results with OpenSignal 2.0 (available free from the Android Play Store). This YouTube video is a good introduction to the app.
OpenSignal seems to do a good job of measuring signal strength and data transmission speed. However, its estimates of cell sites’ locations aren’t at all accurate. I think that it relies upon its own database of cell sites’ geographical coordinates — and these data are inaccurate. It’s frustrating, because everything else about OpenSignal works nicely.
Most of OpenSignal’s many features work well. It has the polished feel of a good commercial app. I gather that OpenSignal regularly updates their cell sites location database, so there’s hope. In the meantime, I give it four out of five stars.
