There is no analog on a DMR signalДЄnd like P25 and NXDN, DMR supports Encryption

Like P25 and NXDN, DMR is a pure digital type of transmission. Like P25 and NXDN, it uses the proprietary AMBE +2 vocoder by DVSIДMR uses color codes in the same way that analog signal uses PL or DPL, P25 uses NAC, and NXDN uses RAN codes. Thus removing the interoperability part of DMR.

And just like P25 and NXDN, manufacturers can add their own equipment into the DMR setup making the end user reliant or locked into a manufacturerвЂ™s equipment. While the DMR protocol does not specify what vocoder to use, the Association voted to use the DVSI AMBE vocoder to ensure interoperability.

Security of supply through a fully open standard.

System flexibility through simultaneous use of TDMA Channels.

Efficient use of infrastructure equipment.

Backwards spectrum compatibility with legacy systems.

Doubling the capacity of existing licenses.

The DMR Association was established in 2005 and is made up of 40 members including JVC Kenwood, Icom, Motorola, Tait, and Hytera to name a few.ДЄccording to the DMR Association, the key benefits of DMR are: Like NXDN, where there is the NXDN Forum comprising of 30 members such as radio and accessory manufacturers, DMR has a DMR Association
