What is DMR (Digital Mobile Radio) | DMR Radio | amateur radio | Aishi, vu3oos

Digital mobile radio (#DMR) is a digital radio standard for voice and data transmission in non-public radio networks. It was created by the European #Telecommunications Standards Institute (ETSI), and is designed to be low-cost and easy to use. DMR, along with P25 phase II and NXDN are the main competitor technologies in achieving 6.25 kHz equivalent bandwidth using the proprietary AMBE+2 vocoder. DMR and P25 II both use two-slot #TDMA in a 12.5 kHz channel, while NXDN uses discrete 6.25 kHz channels using frequency division and TETRA uses a four-slot TDMA in a 25 kHz channel.

The definition given for Tiers is incorrect. DMR Tier I is for simplex mode. DMR Tier-II is for repeater based operations (two time slots on single frequency). DMR Tier-III is for Digital Trunked Radio.
