NEXEDGE™: Multiple Solutions – One System

All NEXEDGE™ products use advanced digital voice
technologies and support both FM analog and new
digital fleets. System type conversion or expansion only
requires software options and/or additional base station
units, i.e., no “forklift” upgrading. Kenwood offers
high-power turnkey NEXEDGE™ conventional, trunked
and wide area trunked IP network solutions with secure
digital voice and an array of advanced digital feature
sets for business and government sectors.

NXDN™ Digital Air Interface

NEXEDGE™is powered by the NXDN™digital air interface, an
FDMA digital access methodology generated with optimized DSP
coding, AMBE+2
4-level FSK modulation technique producing an industry-leading
low bit error rate (BER) digital performance even at weak RF
signal strengths.

● Natural Sounding Digital Voice

VOCODER, a state-of-the-art voice digitization technology,
replicates an individual's natural human speech nuances accurately
unlike early technologies that sounded unnatural and synthesized.
The AMBE+2™ offers superior voice quality at varying signal
strengths even at highway speeds.

● Extended Range over FM

with distance, FM analog reception becomes increasingly noisy and
intermittent. NXDN™'s low BER improves reception in fringe areas,
thereby increasing the effective range by as much as twenty
percent over FM.

● Large Group & Individual ID Capacity

subscriber air interface protocol supports 65,519 GID's & 65,519
UID's for system sharing and large organizations (maximum ID's
available depend on operational mode). ID's can be organized by
agencies, divisions, departments and individuals.

Digital Common Features

NEXEDGE™ supports common call features in both digital

conventional and trunked modes.

● Over-the-Air Alias

sent over the air and displayed on a receiving unit's LCD, so there is
no need to program every fleet alias in every radio.

● UID/GID Validation

the operator system manager for access and call privileges.

● Paging Call

stamped and stored for recall and review - useful for unattended
radio messages and non-voice selective paging operations.

● Emergency Call

to a console, an individual, a group or all groups. This signal can be
triggered by a manual key, a footswitch (mobiles) or man-down tilt­switch (portables).

● Remote Stun/Kill

manently disable a lost, stolen or compromised radio unit over the
air for system security and personnel safety.

● Remote Check

● All Group Call

the system for facility wide announcements, emergencies and
evacuation scenarios.
