The LocationKit API provides a unified library across platforms and devices that can be used to request location information.
LocationKit supports three different methods to obtain location information:
Standalone GPS (SGPS) uses the GPS chipset in devices that can obtain GPS information without network assistance
Cell ID uses the location of the cell the device is currently talking to provide a quick approximate location that can be used to obtain local information
Wi Fi ID uses the visible Wi-Fi networks that the device can see (assuming the Wi-Fi radio is turned ON) to obtain an approximate location that is much more accurate than the Cell ID location when a match is found in the database.
