The CTM-132 modem is an ideal device for vehicle dispatch operations. Its embedded GPS receiver and
CDMA network Auto Connect capability mean that the vehicles position is always known by central
dispatch while the modems communication capabilities provide a data path for sending and receiving
reports and instructions. It is not necessary for a computer or terminal device to be present for the GPS
reporting function to be active thereby allowing the vehicle operator to remove the host device for
operations away from the vehicle without disrupting this position reporting.
