Fylde Micro are active members of the DMR Association and dPMR Mou
Group.
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 (ESTI), and first ratified in 2005.
The standard is designed to operate within the existing 12.5kHz channel
spacing used in licenced land mobile frequency bands globally and to
meet 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 toay focussed
on the Tier II and III licensed categories.

What is dPMR?
dPMR is digital radio protocol specifically targeting highly functional
solutions by using low cost and low complexity technology.
dPMR is a narrowband (6,25 kHz) FDMA technology that is 100% digital
that offers many forms of voice and/or data applications. The FDMA protocol
specified in both TS102 490 and TS102 658 ETSI standards complies with
the European Harmonised Standard EN301 166-2 for use in 6,25 kHz channels.
This group was established in 2007 to provide a forum for all interested
parties who wished to support the latest digital PMR radio technology
known as dPMR. The group currently includes radio manufacturers, chip
manufacturers, protocol and software developers and systems developers.
All these members have expressed the common aim of working together to
ensure the success of dPMR.
