Hi everyone, this is a new amateur digital radio standard? This standard intends to replace the D-Star standard?

I am not giving any specific recommendations, just providing for the technically curious.
Some basic info:
9600 bps channel in 12.5 kHz channel
2 Data/Voice interleave modes with half rate AMBE vocoder
1 Data Only Mode
1 Enhanced voice mode full rate AMBE vocoder
Half Rate vocoder seems to be the same as used in P25 Phase 2 Half Rate, DMR, dPMR, NXDN -- 2450 voice / 1150 FEC (3600 bps)
Full Rate vocoder is doubled to 7200 bps
Details of protocol in above link.
