Question: what is dpmr vs dmr?
Answer: Last week's post on open digital radio standards reveals that the major difference between DMR and dPMR is the choice of multiple access scheme. DMR uses 2-slot TDMA to achieve two communication paths per 12.5kHz channel, whereas dPMR uses FDMA to divide the 12.5kHz channel in to two 6.25kHz sub-channels.
