<div dir="ltr"><div>The Mozilla service is fine for general location requests, such as ensuring you're searching the right area for Yelp!.<br></div><div><br></div><div>Actually mapping towers is much harder. Many rural Verizon towers broadcast correct latitude and longitude. For the rest</div><div>there's no location data, or fake location data. A single physical tower may support 1-4 carriers, and then for each</div><div>carrier 3-36 distinct radio signals on various bands. The OpenCell and Mozilla databases, along with OpenSignal and Sensorly, are rife with bonus towers that don't really exist, and they're often not even close to the proper location. Collected data may skew</div><div>outside the center of the tower's actual footprint, or the footprint may be uneven due to terrain or antenna strength tuning by the carrier (many tower coverage areas are asymmetric on purpose).</div><div><br></div><div>To point a cell repeater or booster correctly, you want the exact location of the target tower. That's where <a href="https://www.cellmapper.net/">https://www.cellmapper.net/</a> comes in.

You can down load the Mozilla database as a CSV file. That will have the lat/lon and identification of every cell tower they know about.<br>

You can also download it from open cell I'd but you need an api key for them.</div></blockquote></div><br></div></div></div>
