NXDN™ Forum and dPMR MoU Collaboration

Suwanee, GA – February 12, 2010 - The Chairman of the NXDN™ Forum recently announced that the NXDN™ Forum and the dPMR MoU have agreed to collaborate on issues of common interest in the promotion of 6.25 kHz FDMA technology.

While the two protocols are not compatible with each other, they share the “basic DNA” of being 6.25 kHz FDMA technologies with the purpose of providing spectrum efficiency and the advantages of digital two-way radio.

The NXDN™ Forum was primarily formed to promote and maintain interoperability of the NXDN™ digital protocol in North America. The dPMR MoU was formed for a similar purpose in Europe. There has been some confusion in the media and the market regarding the differences between these two industry groups and the technology. Some basic clarifications are as follows.


  • NXDN™ and dPMR (digital Private Mobile Radio) are BOTH 6.25 kHz FDMA technologies.
  • NXDN™ and dPMR are not compatible with each other, as the basic air interface format is different.
  • NXDN™ is an open-proprietary protocol supported by the members of the NXDN™ Forum.
  • dPMR is a European Telecommunications Standards Institute (ETSI) open technical standard supported by the members of the dPMR MoU Goup.
  • A number of leading LMR industry companies are members of both groups.

Further details of each organization and the respective protocols can be found on the homepage of each group.
