openBmap!

The OpenSignal app will allow you to do several things, such as:

This app collects GPS locations of GSM/UMTS/LTE/CDMA cell towers and sends them to OpenCellID.org database. It is designed to help map the extent of mobile phone network coverage. It is also possible to collect measurements for private purposes and export them to CSV or GPX files.

collects the GPS coordinates of GSM cell towers for the open source project OpenCellID• sends the collected data automatically or manually to the OpenCellID servers• supports Wi-Fi data transmission• available in four languages: German, English, French, and Spanish• help texts and detailed information on all saved values in all four languages

Cellumap is a revolution in cellular coverage maps, in that the coverage maps here are not created by the network operators, but rather by the users of the network (ie: you!). The coverage maps that are given publicly by the network operators are usually very high-level (ie: not very detailed, no signal strength info) and become quickly out-of-date as the network changes almost daily. Cellumap allows people to plot accurate points (using GPS) and with actual recorded signal strength (and other information) in real-time! Your privacy is also guaranteed, as there is no phone number or account info ever recorded or displayed. »

Service that provides huge database which transforms mobile towers IDs to GPS coordinates

Mozilla is a nonprofit project and global community building a better internet. Mozilla Stumbler is an open-source wireless network scanner that collects GPS data for the Mozilla Location Service, our crowd-sourced location database. As you move around, the app "stumbles" upon new Wi-Fi networks and cell towers. The Mozilla Location Service combines these wireless network measurements to provide geolocation services for Firefox OS devices and other open source projects.

Unwired Labs Location API locates any IoT device worldwide using Cell Towers, WiFi & IP Address.

The GSM Security Map at gsmmap.org compares the protection capabilities of mobile networks. This app collects data and adds it to GSM Map.This application currently only works on Android 4.1.2 Samsung S2 and S3 devices and requires root priviliges during the mobile network data capture.

Track down a GSM/WCDMA cell phone online using LAC (Location Area Code) and Cell ID ,track down a CDMA/CDMA2000 cell phone online using SID,NID and BID, and display its location on Google Maps.
