Short Description Used in many formats of MDTMobile Data Terminal, A mobile data terminal (MDT) is a computerized device used in public transit vehicles, taxicabs, commercial trucking fleets, military logistics, and emergency vehicles, such as police cars, to communicate with a central dispatch office. usage, as well as some ARDIS and DataTAC formats including some Gas companies (this sample for example), Police departments, fire departments, financial companies. It is still around, just not used as much as P25 systems are being used in the 850 MHzMegaHertz (MHz) 10^6 Hz band, and the DataTAC being replaced by higher speeds of the modern-day wireless networks...

This format was developed from MDT4800, this type has faster rates (19.2k) so that it can be used for more purposes other than to be used in the police MDTMobile Data Terminal, A mobile data terminal (MDT) is a computerized device used in public transit vehicles, taxicabs, commercial trucking fleets, military logistics, and emergency vehicles, such as police cars, to communicate with a central dispatch office.'s.
