The System Behind the Wherifone
The Wherifone uses patented location technology that combines
information from Global Positioning System (GPS) of satellites with
the capabilities of GSM/GPRS cellular networks to find the phone.
Should GPS satellites be obscured or a GPS fix otherwise be unavailable,
the Wherify system will provide the approximate position of a Wherifone
by using location information taken from the GSM network where this
information is made available to Wherify. GSM network location
information may also be used by safety officials during an emergency
call to determine the approximate position of the Wherifone device.
When you request a Locate either through a secure Web site or
a Customer Care representative, the Global Location Service Center
contacts the Wherifone via the GSM/GPRS cellular network. The
Wherifone then finds the closest GPS satellites orbiting the Earth,
determines its location, and reports its latitude and longitude coordinates
back to the Global Location Service Center.
The Global Location Service Center processes those coordinates,
pinpoints them with advanced mapping software, and gives you an
approximate street address plotted onto a map. There are two types of
maps: 1) standard online street maps and 2) detailed aerial photo maps.
