GSM Field Test
What is it?
GSM Field Test is a specialized application for Android devices that allows to create coverage map of GSM/UMTS/LTE networks. It displays a map with markers which color depends on a level of signal measured by your phone in a given location.
GSM Field Test helps to determine areas with the best coverage of mobile phone network. The app creates a map with a set of markers. Green markers are placed in locations with a high signal strength; red markers indicate that coverage is rather bad. In the alternative color scheme a poor signal is marked in blue.
There may be two sources of maps: Google Maps or OpenStreetMap.
Map with markers can be saved as a PNG file to a SD card. You can also export markers as KML file (for Google Earth) or CSV file (comma-separated values).
DB Manager allows to import base station locations. The app supports CLF format of version 3.0. You can find more details about CLF files for import on this page.
