DMR Digital Mobile Radio

Digital Mobile Radio (DMR) is an international digital radio standard developed by the European Telecommunications Standards Institute (ETSI), and first ratified in 2005. More than a decade ago, vendors and users of radio systems recognized that the existing analog trunking standards required updates with modern techniques to provide:

Improved voice quality
Improved functionality such as Location information)
Improved security (i.e. Authentication and Encryption)
Improved channel efficiency (2 slot TDMA)
As a result, today, we have a complete set of standards which cover voice, data services, and conformance testing.
DMR aims to provide an affordable, low-complexity digital standard to replace analog radio.

The ETSI DMR Standard defines three different tiers :

Tier I(unlicensed): DMR equipment works in Direct Mode (unit-to-unit) on public frequencies. Tier 1 DMR devices are best for individuals, recreation, small retail, or other situations that do not require wide area coverage.
Tier II(licensed conventional): This Tier is aimed to be a direct replacement for the analog conventional radio system. These DMR systems operate under individual licenses working in Direct Mode (unit-to-unit) or using a Base Station (BS) for repeating. It has a degree of wide-area coverage and is targeted at users “who need spectral efficiency, advanced voice features and integrated IP data services in licensed bands for high-power communications.”
Tier III(licensed trunked): DMR trunking systems operate under individual licenses with a controller function that automatically regulates the communications. It also supports packet data services in a variety of formats, including support for IPv4 and IPv6. It is ideal for organizations looking to migrate from MPT-1327/EADS/LTR (logic trunked radio) systems or who want the full benefits of managed trunking, voice and data solution.

Conventional Radio System

Conventional system is the most basic radio communications system. Conventional, as its name implies, refers to a “traditional” method of frequency utilization. Conventional radios operate on fixed channels and each user group is permanently assigned a fixed frequency or a set of frequencies.

In the case of radios with multiple channels, they operate on one channel at a time. The proper channel is selected by a user. Typically, the user operates a channel selector or buttons on the radio control panel to select the channel.

In multi-channel systems, channels are used to separate purposes. A channel may be reserved for a specific function or for a geographic area. In a functional channel system, one channel may allow road repair crews to talk to the road maintenance office. A second channel may allow road repair crews to communicate with state highway department crews. In a geographic system, a taxi company may use one channel to communicate in a northern area and a second channel when taxis are in a southern area.

One key basic principal to remember when using radio is that only one radio can use one frequency (RF channel) at any one time. If two radios attempt to transmit in the same frequency at the same time, signal collision will happen and cause interferences. Thus, it is important for radio user to be disciplined when using radio to:

Check that no one is talking on that particular frequency or channel
If channel is occupied, wait until it is free.
More often than not, in a congested area with limited frequency, multiple groups share the same frequency which can cause interferences if users are not disciplined.
