Advantages of DMR versus dPMR / NXDN / NEXEDGE

What is dPMR?

• dPMR is an ETSI standardised minimal cost digital radio solution.
• dPMR standards (TS102 490 and TS102 658) were published in 2007 – after DMR. There are 2 tiers specified – Tier 2, modes 2 & 3 are relevant to professional users.
• dPMR operates in 6.25kHz channels. Tier2, Mode2 is conventional; Tier2, Mode3 is trunked.
• NXDN is based on dPMR but is incompatible with it. NexEdge is also derived from dPMR.

What is DMR ?

• DMR is an ETSI standardized low cost, low complexity, professional digital radio solution designed to migrate analog FM radio users to digital.
• DMR standards (ETSI TS102 361) were published in 2005. There are 3 ‘Tiers’ specified – Tier II and Tier III are of interest to professional users.

How to obtain an NXDN ID

How to obtain an NXDN ID:

Search through the existing database and see if the desired ID is available.
One a suitable ID is found, enter the request in the second window.

Quick note: For NXDN ID’s, use the last 5 digits of your DMR ID or a number that is 1 to 5 digits in length. NXDN does not recognize number above 65,519, thank you for understanding!

“We understand there are duplicates that can happen, hence the using of OTAA (Over the Air Alias) is asked”
