What is DMR?

Digital Mobile Radio (DMR) is a digital radio standard specified for professional mobile radio (PMR) users developed by the European Telecommunications Standards Institute (ETSI), and first ratified in 2005.

DMR operates within the existing 12.5kHz channel spacing used in licenced land mobile frequency bands globally and meets future regulatory requirements for 6.25kHz channel equivalence. The DMR protocol covers unlicensed (Tier I), licensed conventional (Tier II) and licensed trunked (Tier III) modes of operation, although in practice commercial application is today focussed on the Tier II and III licensed categories.

Our solutions

Simoco Wireless Solutions has gone further than anyone else in exploiting the capabilities of DMR to develop our own DMR solution, Simoco Xd, which is fully standards compliant yet with a cloud-based distributed architecture.

In practice, this means that Simoco Xd does not rely on switch hardware that would add cost and reduce resilience, and does not rely on proprietary arrangements for routing traffic which is inefficient and limiting in the absence of a genuine control channel.

Our rich heritage and outstanding expertise as a radio and wireless communications systems integrator means we can design, build and operate complete solutions from terminals to infrastructure and applications.


Portable Radios

Portable Radios

Portable radios offer flexibility and reliability, even in demanding environments.

Mobile Radios

Mobile radios can combine data and applications with voice for richer, digitally-driven communications.

Base Stations

Base Stations

Radio terminals and base stations provide a robust and resilient foundation for your communications infrastructure.



Applications are the gateway to more innovation and better customer service, with features like GPS tracking, dynamic call handling and more.


TDE enhances SMR network with Digital Mobile Radio functionality

Télécommunications de l’Est (TDE) has established itself as a leader in the field of communication technology over recent decades, offering telecoms products and services across north eastern Canada and eastern Quebec. We have dramatically enhanced its SMR network with digital mobile radio (DMR) functionality.

Features and Benefits of DMR

  • Reliable and resilient

    With resilience built-in to the base stations, and tough portables and mobiles, Simoco Xd provides a robust platform for always-available communications
  • Natural conversations

    With full-duplex speech it's possible to get the message across more clearly and succinctly. DMR digital technology provides better noise rejection and preserves voice quality over a greater range than analogue
  • Ease of deployment

    Simoco’s fully distributed IP architecture doesn’t require any site, regional or central switching elements resulting in the ultimate level of system resilience at the lowest possible cost
  • Expandability

    Open interfaces are available for dispatch and other applications, plus multiple digital inputs and outputs are available on portables, mobiles and base stations allowing for the creation of a system tailored to specific needs
  • Fully integrated communications

    Simoco Wireless Solutions provides customers with unparalleled expertise in the integration of radio with telephony, IoT devices and other communication technologies, helping to ensure DMR can serve as a backbone for all your communication requirements

Unified Single Block Data (USBD)

USBD allows for near real time GPS updates which provides greater control on your network than ever before which means faster, near real-time updates and a much clearer and comprehensive understanding of your network.
