Abstract
A system and method for activating a GPS receiver or a WiFi receiver on a mobile device may be provided, which comprises determining an approximate location of the mobile device. The approximate location of the mobile device may be determined using cell tower location information. If the approximate location of the mobile device is within a predetermined distance from a desired location, or is “close enough”, then the GPS receiver or the WiFi receiver is activated. The GPS receiver or the WiFi receiver is activated to determine a more accurate location of the mobile device. The approximate and the more accurate location information may be exchanged with another mobile device to allow the user to find one another.
