Teletrac Inc. announced today that its FleetDirector tracking system has been upgraded to run over General Packet Radio Service (GPRS) networks.

The upgrade enables FleetDirector to provide more expansive geographic coverage for its vehicle location capabilities in North America, and higher bandwidth transmission.

Teletrac also today introduced Prism, a GPRS location unit that current FleetDirector users can install in their vehicles to upgrade to the GPRS communication backbone.

The Prism unit is now part of the FleetDirector system package, which includes hardware installed in the vehicle, and Internet-based software that runs over the main office computer.
