Editing Telematics (section)

=== Mobile data ===
[[Mobile data]] is the use of wireless [[data communication]]s using [[radio waves]] to send and receive real-time computer data to, from, and between devices used by field-based personnel. These devices can be fitted solely for use while in the vehicle (Fixed Data Terminal) or for use in and out of the vehicle (Mobile Data Terminal). See [[mobile Internet]].

The common methods for mobile data communication for telematics were based on private vendors' RF communication infrastructure. During the early 2000s, manufacturers of mobile data terminals/AVL devices moved to try cellular data communication to offer cheaper ways to transmit telematics information and wider range based on cellular provider coverage. Since then, as a result of cellular providers offering low GPRS (2.5G) and later UMTS (3G) rates, mobile data is almost totally offered to telematics customers via cellular communication.
