customers value over our competition

The DMR Standard

� 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.

� The standard is designed to operate within the existing 12.5kHz channel

spacing used in licensed land mobile frequency bands globally and to meet

future regulatory requirements for 6.25kHz channel equivalence. The future regulatory requirements for 6.25kHz channel equivalence. The

primary goal is to specify affordable digital systems with low complexity.

DMR provides voice, data and other supplementary services. Today,

products designed to its specifications are sold in all regions of the world.

� 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 focused on the Tier II and III licensed

categories.

� The standards that define DMR consist of four documents. These can be

downloaded free of charge from the ETSI website.

Different Types of DMR

�There are three tiers in the DMR standard.

�DMR Tier I: Unlicensed

� DMR Tier I products are for license-free use in the 446MHz band.

� Tier I provides for consumer applications and low-power commercial applications,

using a maximum of 0.5Watt RF power. With a limited number of channels and no

use of repeaters, no use of telephone interconnects, and fixed/integrated antennas, use of repeaters, no use of telephone interconnects, and fixed/integrated antennas,

Tier I DMR devices are best suited for personal use, recreation, small retail and

other settings that do not require wide area coverage or advanced features.

�DMR Tier II: Conventional DMR

� Tier II covers licensed conventional radio systems, mobiles and hand portables

operating in PMR frequency bands from 66-960MHz. The ETSI DMR Tier II

standard is targeted at users who need spectral efficiency, advanced voice features

and integrated IP data services in licensed bands for high-power communications.

ETSI DMR Tier II specifies two-slot TDMA in 12.5kHz channels.

� DMR Tier II products are commercially available today.

Different Types of DMR

�DMR Tier III: Trunked

� DMR Tier III covers trunking operation in frequency bands 66-960MHz. The Tier

III standard specifies two-slot TDMA in 12.5kHz channels. Tier III supports voice

and short messaging handling similar to MPT-1327 with built-in 128 character

status messaging and short messaging with up to 288 bits of data in a variety of

formats. It also supports packet data service in a variety of formats, including

support for IPv4 and IPv6.support for IPv4 and IPv6.
