About standard

Digital Mobile Radio (DMR) is an open digital mobile radio standard for Professional Mobile Radio (PMR) that was developed by the European Telecommunications Standards Institute (ETSI).

Today, both regulatory bodies and the needs of users are encouraging the move toward digital mobile radio technology to improve spectral efficiency and take advantage of advanced voice and data functionality. The professional market, the largest group of two-way radio users, is now deciding which digital technology will best meet their needs, now and in the future. TDMA two-slot digital mobile radio, the standards-based solution created for these users, offers the best option. The Digital Mobile Radio (DMR) standard on which it is based was designed to deliver a cost-effective, highly functional communication system for professional mobile radio users, as well as the smoothest path toward future interoperability and multi-vendor flexibility.

Wordwide digital two-way radio markets can be roughly divided into three categories

DEFINING THE PROFESSIONAL MARKET

Users of two-way radio communication fall roughly into three groups, each with their own needs and expectations. At one end of the continuum are organizations that simply need fast, convenient, low-cost communication over a limited range. For these businesses, basic low-power radios meet their needs quite adequately.

At the opposite end are those organizations with mission- critical communication needs, such as police and fire departments, public transport and emergency services.

The nature of their work demands the top-level reliability, security and wide geographic range that come only with high functionality, often in customized radio networks. Such systems can be costly, but are an essential component offulfilling the organization’s mission.

Between these two lies the largest group, the professional mobile radio market. These organizations need tocommunicate with and provide information to a workforcethat is mobile, moving about a geographic area to accomplish their jobs. They work in a variety of industries, including transportation, construction, manufacturing, energy and utilities. Some communicate across a single campus — at an institution of learning, a building site or a resort. Others, such as local governments or public safety organizations, need to communicate across multiple sites in a wider region.

For all of them, though, superior communications quality, reliability, functionality, and mobility are business-critical. Professional mobile radio users need clear, unbroken, reliable communications because for them, communication problems create business problems — reduced productivity, wasted time and wasted money. When they can’t reach their workers, essential services are interrupted. Customers needs go unmet. Business is lost.

PROFESSIONAL USERS, PROFESSIONAL NEEDS

Because the mobile professional depends so heavily onreliable communication, the selection of a communication technology becomes a business-critical decision. Aligning the right solution with business goals means choosing a technology that will grow with the organization, offering functionality that streamlines workflow, enhances productivity and improves operational efficiency. Although every organization has its own unique business goals, professional mobile radio users typically have these in common:
  • Clear, reliable communication across the service area — when reliability across a wide area is important, unlicensed on-site two-way radios are usually rejected because of their susceptibility to interference andcongestion. In addition, their limited range does not meetthe needs of many professional market users. Even licensed analog two-way radios, in today’s crowded spectrum, can suffer interference and voice quality degradation at the edge of coverage. Analog solutions also are limited in capacityand expandability as a result of spectral crowding.
  • Cost-effective, customized communications — while unlicensed two-way radios are cost-effective, their basic feature set cannot offer customization to the specific needs of the organization. Radios designed to high-functionality standards aimed at mission critical needs, such as P25 in the U.S. or Terrestrial Trunked Radio (TETRA) in Europe, can be customized, but may not be cost-justifiable for a professional business organization. A public infrastructure solution such as Push-to-Talk over Cellular, with its recurring service usage fees and potentially higher total cost of ownership, can also fall short of meeting cost goals for the professional market.
  • Integrated data communications — to easily send and receive images and information, or quickly locate vehicles and personnel in the field – such abilities have become an expectation, rather than a luxury, for today’s mobile worker. Licensed analog two-way radios lack these integrated data applications. Digital technologies are needed to support these requirements.These needs, then, create today’s search for a comprehensive, cost-effective and future-ready radio solution for the mobile professional.

DELIVERING PERFORMANCE AND PRODUCTIVITY

With the emergence of digital two-way radio technologies professional organizations are  being offered an increasing variety of systems, both proprietary and standards-based, that can better align with their business goals. Digital technology achieves new levels of performance and productivity, with a richer feature set to meet the needs of the professional user.
Digital mobile radio also delivers cost-effectiveness and greater spectrum efficiency, by using less of the available spectrum capacity per call.  That provides higher overall capacity with clearer voice services throughout a geographic range. At the same time, digital protocols enable access to integrated data to improve organizational responsiveness and productivity.

Depending on the technologies used, digital systems can be designed to:
  • Make more efficient use of available, licensed RF spectrum
  • Combine voice and data access in the same device, delivering more information while empowering field workers with systems that are more portable, flexible, and much easier to use than two different and incompatible systems
  • Enable integration and interoperability with back-end data systems and external systems
  • Combine analog and digital voice in the same device, easing the migration to digital while preserving investments in analog technology
  • Provide strong, practical, easy-to-use privacy solutions without the significant loss in voice quality that analog scrambling can cause
  • Enable flexible and reliable call control and signaling capabilities
  • Provide increased capacity without additional base stations
  • Flexibly adapt to changing business needs and new applications through a modular architecture

THE DMR STANDARD

3.png

European Telecommunications Standards Institute (ETSI)digital two-way radio standards address the needs of each market segment. For the professional mobile radio user, the relevant standard is DMR Tier 2/3.

To meet the challenges of large scale migration of professional users to digital radio, the globally recognized European Telecommunications Standards Institute (ETSI) has developed a new digital standard called DMR (Digital Mobile Radio).DMR includes standards for all of the broad range of business radio use, but for the conventional radio professional market, the relevant standard is defined in DMR Tier 2.

In developing the DMR Tier 2 standard, ETSI considered a number of alternative technologies. Knowing the needs of the professional/business-critical user, they sought a technology that promised  the high reliability, improved range, higher data rates, more efficient use of spectrum, and improved batterylife these users demand.

Because the organizations that would use the new standards- based technology work in industries with a broad range of communication demands, ETSI sought a technology path that could support a similarly rich set of features, including fast call set-up, calls to groups and individuals, short data and packet data calls. Their choice would need to support individual

calls, group calls, broadcast calls and, of course, a direct communication mode among the mobiles. Other important functions such as emergency calls, priority calls, full duplex communications, short data messages and IP packet data transmissions would also be supported in DMR.

Perhaps most important to professional users, ETSI recognized the significant investment many organizations already have

in analog radio systems. The DMR Tier 2 standard wasspecifically designed to ease their migration from analog to digital. The standard fits in existing bands and imposes no fundamental changes in architecture. Instead, it focuses on changing the over-the-air protocol to facilitate the use of applications that are beyond the capability of analog systems.

The protocol ETSI chose is two-slot TDMA.

CONCLUSION

As they prepare to migrate to the greater efficiencies and capabilities of digital mobile radio, professional users need to make a careful choice. Motorola’s MOTOTRBO makes the choice easier by adhering to globally recognized standards.A standards-based solution assures a smooth, well defined migration path, as well as the interoperability and compatibility of multi-vendor equipment that provide for fair market, competitive alternatives.



Benefits

Expanded digital voice, data, and control capabilities delivered over a given slice of RF spectrum.
TDMA digital two-way radio increases capacity and flexibility to support more users in more ways.

Increased capacity with lower licensing and equipment costs.
TDMA technology enables two virtual channels within a single 12.5 kHz licensed repeater channel. This provides twice the calling capacity for the price of one license. And because there’s only one “real” channel, a second call doesn’t require a second repeater.

Clearer voice communications over a greater range.
When signal strength drops off with distance, digital error-correction technology can accurately deliver both voice and data content with virtually no loss over a given coverage area. Audio quality is more consistent across a given coverage area.

Improved battery life.
In a two slot system, each individual radio only uses half the battery power of an analog radio transmitting at the same wattage. Since transmitting is the most energy-intensive operation, digital TDMA two-way radios can enable operation up to 40 percent longer than typical analog radios.

Enhanced functionality.
In MOTOTRBO’s two-slot TDMA system, each slot delivers an independentvirtual channel at the repeater that can be used for voice calls, data communications, or a combination of the two. MOTOTRBO provides improved background noise suppression, built-in privacy, and optimized workgroup communication with one-to-one, one- to-many and one-to-all calling models and signaling features such as push-to-talk ID, emergency, remote monitor, and radio check.

Easy migration.
MOTOTRBO’s ability to operate in both analog and digital modes enables a smooth, planned migration at a user’s own pace.

Advanced applications
With built-in GPS, MOTOTRBO provides the ability to track people and assets, such as vehicles. MOTOTRBO also offers text messaging capability, enabling messaging between radios and dispatch systems, radios and email addressabledevices and to remote PC clients attached to radios.
