The main purpose of the device is to work as a GPS/GSM tracker to perform transportation logistics tasks, using the mobile operator's GSM network and GPRS/EDGE technology to transmit data to the server. This device can also be used as a GSM car alarm, which transmits an alarm siren of conventional car alarms already established, as well as to remotely block the engine using a mobile phone. In the GPS/GSM tracker, the concept of wireless software changer (SW) is used through GPRS/EDGE technology.
