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.
NEXEDGE
™
is powered by the NXDN
™
digital air interface, an
FDMA digital access methodology generated with optimized DSP
coding, AMBE+2
™
voice coding technology, unique filtering and a
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
The AMBE+2™
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
As RF signal strength weakens
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
The NXDN™
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.
● Spectrum Efficient Now
The NXDN™ digital air interface
and equipment are capable of all channel bandwidths.
• FM Analog @ 25 & 12.5 kHz Channels
• NXDN™ Digital @ 12.5 & 6.25 kHz Channels
NXDN™ Digital Air Interface
NEXEDGE™ supports common call features in both digital
conventional and trunked modes.
● Over-the-Air Alias
A calling units UID alphanumeric alias is
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
Each unit and talk group are validated in
the operator system manager for access and call privileges.
● Paging Call
Up to five UID unit-to-unit pages are dated, time
stamped and stored for recall and review - useful for unattended
radio messages and non-voice selective paging operations.
● Emergency Call
Subscriber units can declare an Emergency
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 tilt-
switch (portables).
● Remote Stun/Kill
Enables a dispatcher to temporarily or per
manently disable a lost, stolen or compromised radio unit over the
air for system security and personnel safety.
● Remote Check
Enables a dispatcher to check if a unit is on or
in range.
● All Group Call
A selectable All Call GID calls all talk groups on
the system for facility wide announcements, emergencies and
evacuation scenarios.
