The Southgate news reports that the technical specification
for NXDN which is an FDMA digital voice technology supported
by Icom and Kenwood, is being opened to the public domain.
According to a press release the chair of the NXDN Forum has
announced that the Forum Steering Committee has decided to
open the NXDN technical standards to the telecommunications
industry.
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. NXDN Digital products are deployed throughout the
world in hundreds of thousands of professional radio
applications.
The specification is currently available in response to an e-
mail request but the NXDN Forum indicates it will be
available for direct download later in the year. Interested
companies can obtain the information for the NXDN technical
standards by following the instructions on the forum web
site at www.nxdn-forum.com/instructions

The NXDN Forum says that it will continue to accept new
members after opening the technical specifications and will
govern the NXDN specification and related interoperability
testing and certification. (Southgate)
