CellMapper is a crowd-sourced cellular tower and coverage mapping service. By contributing data to the website, you can help map actual coverage of cellular networks based on real life conditions.
Once the data is uploaded to the site, it will be used to extract details of individual antennas on each cell phone tower along with the position and technical details of that tower. Likewise, the coverage and signal strength of the network in areas that have been mapped.
To view the maps, click Coverage Map above or click here.
To contribute, simply download the app and enable live upload (Settings -> Enable Instant Upload). After you do this, leave CellMapper running in the background during the course of the day. Once data is received, it is almost instantly processed and you can see the results within the app within minutes.
Alternatively, you can use the "Upload Later" (Menu -> Upload and Statistics) option to upload later if you have no coverage or do not want to use data.
Another option is to support the site by providing a financial contribution. You can contribute via PayPal.
CellMapper runs on Android 2.3 and later, Windows Mobile 6, and BlackBerry OS 7.1 and earlier.
In general, we only collect network information and some very basic information about your phone. See the privacy page at the bottom of the page for more details.
