What is DMRWhat is DMR In 2005ETSI released DMR standard DMR (Digital Mobile Radio) is a digital radio standard for Professional ( g ) g
Mobile Radio (PMR) DMR is specifically targeted at systems where analogue PMR is currently
applied and designed to deliver digital voice, data and other supplementary pp g g , pp yservices in a simple and low cost manner, and to meet future regulatory requirements for 6.25kHz channel equivalence.

will not be approved after 2011 due to congestion. And all public safety equipments have to be migrated by 2013.
GB: non frequency efficient (12 5kHz) equipment will not be approvedGB: non frequency efficient (12.5kHz) equipment will not be approved after 2010 . Analogue radio will not be approved after 2011. And all radios have to be migrated into digital by 2016.

R d d i t tReduced equipment cost Compared with FDMA solution, 2 slot TDMA solution allows 2
simultaneous calls through 1 repeater, which helps reducing equipment cost
L b tt lifLonger battery life 80% of battery is used for transmission; Two-slot TDMA, however, offers a good way forward. Since an , , g yindividual call uses only one of the two timeslots, it requires only half of the transmitters capacity. 40% Battery Life Improvement with TDMA (2000MAH : 14H vs 10.5H)
