NXDN: A brief overview

NXDN is a very narrowband protocol employing 6.25/12.5 KHz FDMA technology (It is generally accepted that 12.5 kHz channel spacing is narrowband as per the FCC mandate.) (More on this later in The history of NXDN™).

NXDN™ is the result of a joint technical alliance between Icom Incorporated and JVC KENWOOD Corporation. At the beginning, the main goals of this collaboration were to provide a low complexity digital two-way radio protocol that satisfied the FCC narrowbanding mandate at the initially proposed deadline of 2005, be a future-proof protocol that would still be viable even when 12.5 kHz spectrum became full and to offer an alternative “de-facto” standard to the Land Mobile Radio (LMR) industry that allowed the development of digital radio products without the

Advantages of DMR versus dPMR / NXDN / NEXEDGE

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.

NXDN frequency is NOT listed on this site, but listed in inaccurate Repeater Directories. It used to be on that frequency but that frequency has changed to DMR

NXDN is used on the main repeater site on a frequency of 443.050 MHz as well as FM modulation, which takes priority over NXDN

I will have to correct our site information.

Thank you for pointing that out.

NXDN Simplex?

I think I know the answer to this question but is it possible to have 2 Kenwood NX Portables programmed on a simplex channel but also be NXDN Digital quality without going through a Nexedge repeater?

NXDN World Wide

A few of us have been working pretty hard. The fruits of those labors are starting to show. I've got reflectors built and functional. This solves one of the major shortcomings of the both the Kenwood and Icom software where they are limited to 15 IP addresses that they can link to. I've also got support for running them over private IP address spaces so you can run them on a 4g wireless connection if you want too.

Next up is protocol conversion between Icom and Kenwood, and then smart portals that will honor local vs linked traffic without needing to build up or tear down a link.

NEXEDGE what is

NEXEDGE what is it

No they do not do training videos, hence my video. I set this up using the add on software ($299) and two Nexedge radios.
