Telematics is a multi discipline field, encompassing telecommunications, vehicular technologies, road transportation, road safety, electrical/electronic engineering, multimedia, wireless and Internet technologies.
Telematics can involve any of the following:
Sending, receiving and storing information via telecom devices, to enable control of remote objects
The use of GNSS technology with computers and mobile comms related to automotive navigation systems.
The integrated use of telecoms and infomatics, to control vehicles on the move
Vehicle Telematics, (which is most Telematics usage today) specifically defines the use of such systems within road vehicles, including GPS navigation, integrated hands-free cell phones, wireless safety communications and ADAS.
