FleetMatics company is the company that provides very good truck fleet location tracking through the satellite tracking system called FleetMatics GPS Tracking System. But the name of their device does not uncover the whole truth about its working principle. It has the GPS in its name but uses not only the GPS frequency band in its operational process.
Indeed, FleetMatics GPS Tracking System uses GPS satellites to track the location of its targets, but the data gathered by their tracking device must be transferred to the data centers. It is done by the GPRS signal in real time. By the way, the GPS location tracking feature is real-time too. So blocking only GPS frequency is not the option for you.
Yet you can deal with their combined tracking system because GPRS frequency is the part of the GSM band used for the data transferring. So all you have to do is to get rid of the FleetMatics GPS Tracking System because now you are aware of all their tricks and are able to counter them! ;)
