How does GPRS locate my car?

General Packet Radio Service or GPRS is a standard for mobile telephony derived from GSM (Global System for Mobile communications). It is sometimes called "2.5G", as it lies halfway between GSM (2nd generation mobile communications) and UMTS (3rd generation mobile communications).

GPRS allows higher data transfer speeds than GSM and is better suited to the transmission of data required for the geolocation of cars.

A GPRS module uses a modem and a SIM card. It uses the antennas of the GSM / GPRS network, and then transfers data to a processing centre which decodes the data before transmitting it in a format that can be used by mapping software.

Note that in order for GPRS tracking systems to work, the car must be in an area covered by this mobile communications network.
