What is the DMR?

Digital Mobile Radio (DMR) is an international digital radio standard developed by the European Telecommunications Standards Institute (ETSI), and this standard:

  1. Improved voice quality.(The voice tranmitted under Digital mode will be better than analog mode).
  2. Improved functionality.( Like the GPS function)
  3. Improved security.(Like the Encryption)
