Cellular Tower Maps


This website is dedicated to helping map the extent of cellular network coverage. This is done by crowdsourcing data using the CellMapper mobile application. Once the data is received, the coverage areas are calculated and cell phone tower locations are estimated based on available information.

An example of a thoroughly mapped network can be see on the map of T-Mobile 3G coverage of Seattle, WA.
