The service provides geolocation information by detecting the nearest cellular phone access point and marking its location.
It was developed to provide location to a phone's systems without the need to access a global positioning system (GPS) signal. After identifying an antenna, it consults constantly updated databases of exact antenna locations, then provides those coordinates as the phone's approximate location.
API methods support submission of parameters identifying the mobile country code (MCC), mobile network code (MNC), and local area code. The API returns latitude and longitude coordinates along with a value indicating the antenna's coverage area as a proxy for location accuracy.
