About Us

21st century digital radio standard

We work with our members, worldwide, to ensure that DMR is the most widely supported digital business radio standard. Our members are companies, organisations and individuals who use or build DMR products or those working to support the DMR standard in other ways. By using a combination of education, awareness, certification and interoperability training we operate to make sure that business buyers of today’s digital radio technology have the security of knowing that they are investing in the future. We’re here to ensure that DMR products exist within a successful, open, multi-vendor chain.


Established in 2005 as the DMR-MOU Association to support ETSI during the DMR standardisation process our membership is open to any organisation or individual interested in using or building DMR products or in supporting the DMR standard in other ways. We’re in frequent and direct dialogue with regulators, trade bodies and standards organisations around the world to maintain the DMR standard both for our members and for all other users.

Mission and Objectives

For DMR we will:

  • support the growth of the market
  • create and maintain an interoperability testing and certification program
  • offer education, promotion and discussion about the standard
  • work with regulators to develop an environment in which the technology can flourish


Members Assembly

The Members Assembly drives the DMR Associations. It begins all the actions and work needed to achieve the purposes of the DMR Association and it determines the membership fees, reviews the work of the Marketing and Technical Working Groups, elects Chairman of the Organisation. Category One and Category Two members have voting rights and all member companies have the right to attend meetings. Most of the Association’s detailed work is undertaken by two specialist working groups; one for technical issues and one for marketing, both reporting to the Members Assembly. The officers of the Association are elected from the membership.

Mario Micheli

Chair of the Association
Mario is a telecommunications engineer who works for Leonardo formerly Selex ES. During his 25 year career, Mario has held numerous technical and management positions in the professional and military communications business.

“I am convinced that a genuine interoperable and multi-vendor product offering is a key to the success for a PMR technology. DMR equipment, regardless of the manufacturer, is to be truly interoperable allowing for a healthy competition in the market that will result in continuous product innovation. For these reasons I firmly believe that DMR is positioned as the ideal candidate to substitute many legacy analogue systems and that the DMR Association has a fundamental role to achieve this objective.”
