    "The location-tracking software itself, developed by a 15-year-old student at the university, draws upon triangulation technology used by global positioning system (GPS) devices. The PDAs figure out their locations by comparing the strength levels of signals traveling from the devices to various Wi-Fi antennas."

    GPS does not do triangulation via signal strength. It does it via time measurement. Someone needs to buy a clue.
