Networkcar announced that it entered into an agreement to add Motorola's G20 wireless module to the next-generation of its GPRS-based Networkfleet wireless, vehicle-management system. Networkfleet collects data on vehicle location and engine performance of a vehicle's engine computer and then wirelessly transmits the data to a network operation center. The addition of the G20 wireless module will add secure, wireless coverage options to the existing system, according to Networkcar.
