InteliTRAILERTM Inc.s AVL units incorporate a wireless transmitter (radio) that uses universally available cellular networks to transmit location data in real-time. Passive GPS systems accumulate GPS position data in their memory. When the vehicle returns to the home/base, this data is retrieved from the unit (by either physically retrieving a ‘memory card’ from the device or wirelessly sending the data to a base station using some sort of proprietary, short-range 900/2400 MHz radio transmitter included in the Passive GPS device). Passive GPS systems cannot provide real-time location information.
