NXDN stands for Next Generation Digital Narrowband

NXDN was created in 2003 with a joint venture of Kenwood and Icom.\xa0 \xa0The protocol was announced at IWCE in 2005 and the first units arrived in 2006.\xa0 It wasn't until 2017 that NXDN was published by the ITU-R as an international digital land mobile system.

NXDN was created to satisfy the 2005 FCC Narrowbanding mandate.\xa0 Originally created for business users, NXDN is used by public safety and even the military.

Overseeing NXDN development and standards is the NXDN Forum.\xa0 A 30 member community including JVC Kenwood, Icom, Anritsu, The Boeing Company, and Zetron.

NXDN Comes in 3 flavors

• NXDN Standard (As defined by the CAI)
• Kenwood's NEXEDGE
• Icom's IDAS\xa0

NXDN operates using FDMA over 12.5kHz or 6.25kHz wide bandwidth.\xa0\xa0
