GSM Field Test
What is it?
GSM Field Test is a specialized application for Android devices which allows to monitor a signal of GSM/UMTS network by displaying colored markers on a map. The colour of a marker depends on a level of GSM signal measured by your phone in a given location.
GSM Field Test helps to determine areas with the best coverage of mobile phone network. Result of its work is 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.
There may be two sources of maps: Google Maps or Open Street Maps.
The app needs precise information about location, that's why the GPS must be turned on. In other case markers aren't put on a map.
Map with markers can be saved as a PNG file to a SD card. Other way to save results is to export markers as KML file (for Google Earth) or CSV file (comma separated values).
