DMR

Moving to digital radio communications brings many advantages – crystal-clear audio, greater coverage, more efficient use of spectrum, integrated data communications and longer battery
life, amongst many others. Sepura’s family of “plug-and-play” Digital Mobile Radio (DMR) products brings professional and industrial users all these advantages and also offers the additional benefits
of staying true to Sepura’s commitment, as a world leader in digital radio communications, to provide robust, feature-rich solutions, utilising open standards.

Moving to Sepura DMR

In radio communications, digital technology offers a number of key advantages over existing analogue options and DMR is no exception. As an open standard, DMR offers confidence in long-term supply, greater choice and more rapid product development.
The key advantages that DMR offers users include:
› Better audio quality
› Better battery life
› Better coverage
› Increased capacity
› Integrated data capability

Superior audio – DMR provides considerably enhanced audio clarity, particularly when compared with legacy analogue systems. Improved noise rejection, followed by enhanced error correction, ensures that superb audio quality is achieved.
Better coverage – existing analogue users can often improve their radio coverage by switching to DMR.
Longer battery life – DMR uses Time Division Multiple Access (TDMA) technology, which effectively compresses the transmission into many small time slots. This means that the demands on the radio’s battery are reduced, and up to 40% longer battery life can be achieved (when compared with analogue), thus ensuring that it is able to cope with long shifts or extended use.
Efficient use of radio spectrum – DMR offers a doubling of the capacity of 12.5 KHz channels by enabling a single 12.5 KHz channel to support two simultaneous and independent calls (either voice or voice and data). With radio spectrum in limited supply, a technology which makes good use of this scarce resource will enable its usage to be maximised.
Advanced data capabilities – through its use of TDMA technology, the DMR standard not only specifies significant data capabilities, but also provides the capacity to run data applications by making efficient use of radio spectrum.
Backwards compatibility – as DMR utilises 12.5 KHz channels, it is fully backwards compatible with analogue systems, meaning that users can use their DMR radio to talk to both DMR and analogue users. This eases transition and also ensures communication with analogue systems operated by third parties, such as on-site contractors.

The Sepura advantage

Sepura has a pedigree that can be traced back, through well-known names such as Phillips and Pye, over 100 years in radio communications, and has been a world leader in the digital sector for over 15 years. The company has already shipped over one million digital radios, has a global footprint and is the market leader in many countries around the world.
Built on providing robust, secure solutions for use in tough, harsh environments and utilising open standards, Sepura’s unique DMR product family remains true to these principles and provides a total DMR solution.
In addition to this key benefit, Sepura also offers:
› Unrivalled audio expertise
› Interchangeability with Sepura current / established accessories – which means that users have access to a wide, well thought-out accessories range
› Access to a range of new and existing data applications via the industry-standard peripheral equipment data interface (PEI)
› Sepura product quality and reliability
› Support from a leading global supplier that is dedicated to open standards
› Global reach through an extensive network of channel partners
