The technical specification for NXDN™, a FDMA digital voice technology supported by ICOM and Kenwood, is being opened to the public domain.
For the past 5 years both ICOM and Kenwood have been producing VHF/UHF mobiles, handhelds and repeaters to the NXDN™ standard. The equipment has a transmitted bandwidth of 4.0 kHz and is typically used in 6.25 kHz channel spacing systems.
The specification is currently available in response to an email request but the NXDN™ Forum indicates it will be available for direct download later in the year.
The NXDN™ press release reads:
The Chair of the NXDN™ Forum announced that the Forum Steering Committee will open the NXDN technical standards to the industry public.
Interested companies can obtain the information for the NXDN technical standards by following the instructions on the NXDN Forum web site http://www.nxdn-forum.com/instructions/
NXDN Digital products are deployed throughout the world in hundreds of thousands of professional radio applications. As NXDN’s popularity continues to grow it will easily become the primary next generation narrowband two-way radio digital protocol and increase demand in the market for products from multiple vendors. To accelerate the spread of NXDN and to expand on the opportunities it provides, the NXDN Steering Committee has agreed to open the technical specification to the public domain.
The NXDN Forum will continue to accept new members after opening the technical specifications and will govern the NXDN specification and related interoperability testing and certification.
