NXDN™ and dPMR
NXDN is a different protocol also based on 4FSK FDMA for 6.25kHz. For further details you are invited to visit their Forum website:www.nxdn-forum.com

dPMR is a digital radio protocol specifically targeting highly functional solutions by using low cost and low complexity technology.

dPMR is a narrowband (6,25 kHz) FDMA technology that is 100% digital that offers many forms of voice and/or data applications. More >>

 

 

dPMR is an ETSI Standard... Why is this important?

ETSI standards could be described in general as being 'definitions and specifications for products and processes requiring repeated use'. They are certainly a set of rules for ensuring quality.

Standards can be found throughout our daily lives but why do we need them?
Rather than asking why we need standards, we might usefully ask ourselves what the world would be like without standards. Products might not work as expected. They may be of inferior quality and incompatible with other equipment, in fact they may not even connect with them, and in extreme cases; non-standardized products may even be dangerous.
