What is NEXEDGE / NXDN ?
•
NEXEDGE
– Is a trademark name of JVC KENWOOD Corporation and a generic
term used when referring to KENWOOD‟s Digital Communication
System
• NXDN
– Is a trademark name of JVC KENWOOD Corporation and ICOM
Incorporated
– NXDN refers to the Digital Air Interface protocol used by both JVC
KENWOOD and ICOM
– NXDN Forum opened the NXDN technical standards to the industry
public in summer 2012.

Multimode / Easy Migration
•
NEXEDGE Equipment – Ready Today & Tomorrow
– FM Analog at 25 and 12.5 kHz Channels
– NXDN Digital Air Interface at 12.5 and 6.25 kHz. Channels
•
NEXEDGE provides a graceful migration path from analog to fully
digital or new installations
– NX and NXR equipment supports all modes
– NXR base use existing FM site equipment in FM and Digital Modes
– Shared Mode for Trunked operation
• NEXEDGE trunked traffic channels can be shared with existing external
analog conventional or LTR/MPT trunked logic controllers, as a transition
to NXDN trunking.

NEXEDGE Advantages
Compare to TETRA
•
Coverage
– Communication distance*
• TETRA : Mobile@8km/h, Suburb, 10W  11km
• TETRA : Portable@8km/h, Suburb, 1W  5.7km
Less than half of UHF NEXEDGE‟s Communication distance
Almost 1/4 of VHF NEXEDGE‟s Communication distance
•
Smaller number of Base station*
– Need 4-6 (16-18) sites to cover the area which NEXEDGE can cover
by 1site in UHF (VHF). This affects to the infrastructure cost.
•
VHF availability
– Easy to secure the frequency if customer currently use VHF system
•
Speech Quality / Clarity
* Based on JVC KENWOOD‟s simulation
13
NEXEDGE Advantages
Compare to MPT
•
Coverage
– NEXEDGE‟s coverage is 20% wider than FM analog
(will vary depends on the conditions)
•
Performance in Mobile
– NEXEDGETM performs better coverage especially when the radio
moves at high speed
•
Channel efficiency
– 6.25kHz mode of NEXEDGETM enables high channel efficiency
Example:

G8 Hokkaido Toyako Summit
Security management
• For the G8 Summit at Lake Toyako in
Japan, which was held in July 2008,
KENWOOD's NEXEDGE was chosen
to provide radio communications for
Japanese Government.
•
•
Ministry officials wanted to link three
sites - while allowing radio-to-radio
communications within each area.
Airport

During the Summit the system
performed flawlessly and the Ministry
expressed its satisfaction.

The Venetian, Las Vegas
Hospitality
•
•
•
Growth
–
With the addition of the Venezia Tower and the Palazzo the
management needed to add another 1,000 radios to the
2,000 already in use. This was something that could not be
achieved with their LTR system. Buying new frequencies
was too expensive. Also, because it is a resort the
Venetian‟s radios are used a great deal at night, when
support is not easily available, so reliability is especially
important.
Migration
–
Fortunately the Venetian found exactly what was needed in
NEXEDGE as it allowed them to migrate gracefully from
their 12-channel analog system (12.5kHz), doubling
capacity to 24 channels (6.25kHz). Being adaptable and
scalable were important factors in this decision, but so too
was cost. Other solutions would have meant purchasing
and deploying 3,000 radios at once – a major investment
and logistically problematic.
Benefits
–
Meanwhile, the Venetian‟s considerable investment in
analog radios, headsets, and batteries continues to serve
the staff in other departments. But as the migration
progresses, the digital benefits accrue. For example, in
fringe areas and elevators where signal strength was a
problem, voice quality is now crystal clear.

CN Tower, Toronto
Telecommunication network operator
•
Capacity
•
Solution
•
Cost efficient
– The CN Tower‟s new FDMA-based digital trunked
system – with its 6.25 kHz capability ensuring
clean, clear and defined signal propagation. This
was not previously possible with the LTR system.
– As the new system uses the same 450 MHz band,
migration was smooth and the CN Tower is a very
satisfied client. NEXEDGE has proved to be an
ideal solution for the tower and for MBC, which has
been serving the commercial SMR industry in
southern Ontario.
– Companies that had been using cellular are
strongly attracted by the cost-efficient wide-area
coverage made possible by NEXEDGE
technologies and economical IP networking, as
well as by the potential to exploit GPS and
messaging capabilities.

SP-PSA International Port, Vietnam
Port Operation
• Winning out over strong competition,
NEXEDGE was chosen by Singaporebased PSA International, the world's
second largest port operator, for its
new container operations in Vung Tau,
Vietnam.
•
Workers at this large facility are now
using over a hundred Kenwood radios
and further expansion is scheduled.

Hessen Road Maintenance System, Germany
Motorway maintenance
• User: Building, Tunnel and service
vehicles of the motorway
maintenance area for summer and
winter services.
• The motorway maintenance area
is 50–60 km. For this distance
section operates approx. 35-50
vehicles.
• VHF Conventional IP network
• Switching from the existing
analogue to a digital system
67
TGS (Turkish Ground Services), Turkey
Airport Ground Services
• Air terminals and cargo depots provide
an ideal environment to demonstrate
the advantages of digital radios, and
TGS – which operates in six of
Turkey‟s busiest airports – has joined
the ranks of enthusiastic NEXEDGE
adopters.
•
Orgen, the local distributor, provided a
convincing argument for switching to
Kenwood‟s flagship digital radio
system from MPT trunking system,
and TGS is already planning to deploy
NEXEDGE at 35 sites by 2013.
68
Digital SMR Service, Malaysia
・
Analog trunked radio service for public and private network users in
800MHz were used in Malaysia in the past.
 Cause traffic congestion, missed calls, garbled messages, degraded
voice quality
・ Government decide to switch from 800MHz to UHF 410-430MHz for public
