Reliability

NEXEDGE uses the AMBE+2™ VOCODER, a state-of-the-art
voice digitization and compression technology offeringenhanced Forward Error Correction (FEC) and noise reduction
for superior clarity at varying signal strengths for all digitalcall features.

NEXEDGE systems use the NXDN digital air interface, a suiteof digital communications protocols using 4-Level FSK (4LFSK)
modulation capable of operating in 12.5 kHz and 6.25 kHz
bandwidths. NEXEDGE voice security enhances personnel safety,
reduces risk and thwarts possible information breaches by protecting
sensitive communications.

Loud & Clear – Thanks to Advanced
Digital Processing

Superior Audio Clarity with
Extended Coverage

A key element of the NXDN air interface is the AMBE+2™ vocoder
which digitizes speech while retaining natural voice nuances,
performs noise reduction, introduces FEC and compresses voice
data to accommodate land mobile radio spectrum bandwidthand data rates. Next, the radio’s digital signal processor (DSP)
protocol packages the vocoder, signaling, control, and FEC data
together, converting it to a uniquely filtered 4-Level FSK digital
waveform that modulates the transmitter. This results in a low
bit-error-rate (BER) digital air interface so you get robust
communications even in weak signal strength areas.

As RF signal strength weakens with distance, analog reception
becomes increasingly noisy and intermittent. The low BER of
NXDN improves reception in fringe areas, thereby effectively
increasing coverage by as much as 20% over FM analog, resulting
in a 50% increase in coverage area for digital 6.25 kHz.
Furthermore, even compared to digital 12.5 kHz bandwidth
operation such as DMR, the narrower 6.25 kHz bandwidthenabled by the FDMA technology of NXDN extends range by
15%. Receiver filters are narrower and can thus reduce noise.
The net result is superior clarity over a 30% wider coverage area.

ESN Radio Validation

Spectrum Efficiency and Stability

Each NEXEDGE subscriber radio has a unique and unchangeable
factory embedded Electronic Serial Number (ESN) that can bevalidated for trunked system access. In the event a radio is lost,
stolen or compromised, the ESN can be disabled, enabling all otherradios to communicate in their talk groups without disruption.
The operator’s original ID numbering system is preserved because
only one subscriber unit is disabled and talk groups shared bymany users are unaffected.

The NXDN air interface is capable of fitting into both 12.5 kHz
and 6.25 kHz bandwidth channel operation to ensure rock-steadyfrequency stability, exceeding all regulatory and emissions mask
requirements in all bands.
What’s more, the narrower 6.25 kHz bandwidth mode offersa high CNR (carrier-to-noise ratio), so radios can communicate
over greater distances.

Radio Password Protection

All NEXEDGE system configurations validate unit and group
IDs for subscriber access. Commercial and private operators
can easily activate & deactivate subscriber units via remote
programming or system management software. This is ideal fororganizations with frequent personnel changes, so radios canbe used by contractors, vendors and seasonal/temp workers.

Each radio can have a required password to authorize operation,
thus adding an extra level of security against unsanctioned radio
use.

OAA: Over-The-Air-Alias

Current analog and NXDN digital fleets can share the same
frequency in conventional Mixed Mode, continuing service toaging analog fleet radios as new digital radios are deployed.
NEXEDGE radios, capable of both conventional analog and digital
operation, can talk to both old and new radios. The Mixed Modeoperation is available in base, repeat and direct modes in thefollowing bandwidth combinations: 25, 20*or 12.5 kHz analog
with 12.5 or 6.25 kHz NXDN (25 kHz mode capable equipment isonly available where permitted by government regulations).

A calling unit’s User ID (UID) alphanumeric alias is sent over
the air and displayed on the receiving unit’s LCD, so there is noneed to program every fleet alias in every radio.

Channel complex systems require a dedicated control channel(CCH), but it can be difficult to set up such a channel in a waythat is cost-effective. However, NEXEDGE Gen2 employs anelegant solution: the CCH and TCH temporarily exchange roles
to expand air capacity. This Dual Functional Channel enables you
to receive the same level of performance provided by a dedicatedcontrol channel but without having to make a large investment.
This approach also maximizes traffic capacity without increasing
the number of frequencies, and maintains an even load distribution
on the repeaters, a solution that makes sense for sites with limited
traffic.

Scalability
As well as traditional conventional systems,

NEXEDGE allows you to link up to 1,000 sites(up to 24 networks).

NXDN Type-C Trunked Systems

NXDN Type-D Trunked System

Specified as the full-featured digital protocol by the NXDNForum, NXDN Type-C has been used for NEXEDGE since 2007.
As well as Type-C it is known as Control Channel based orCentralized Control trunking, which is controlled centrally using
a dedicated control channel that is continuously transmitting andreceiving. As with MPT 1327, registration is required.

Economical alternative to the Type-C trunked system,
Type-D trunked system is based on digital LTR® protocol
specified by the NXDN Forum. Unlike Type-C trunking, there isno dedicated control channel: trunking is under the control of
the home repeater assigned to each radio. Similar to LTR, there
is no need for registration.

Type-C trunked systems provide increased call capacity,enhanced call capabilities, improved security and fastercommunications with less user interaction than conventional
systems. The system automatically assigns channels for fasterand more efficient use of spectrum, allowing users to concentrateon the job at hand.

Digital Conventional Systems

Digital Conventional IP Networks

NEXEDGE conventional systems offer capabilities beyond analog
conventional systems. With large unit ID and talk group ID
capacity, operators can identify and segment different departmental/agency groups and sub-groups on shared channels.
Mixed Mode allows service to both analog and digital fleets atthe same time.

NEXEDGE Conventional IP Networks offer wide area coverage orcoverage fill-in extensions.
• 16 or 48 Site Configurations NEXEDGE Conventional IP
networks link up to 16 or 48 digital conventional repeaters
into one system for wide area coverage or coverage fill-in
extensions.

• RAN (Radio Access Number) base units include a 16 RAN

selective calling.
• 1,000 UIDs Large unit ID capacity for individual selective
calling.

• Priority Monitor Monitor for up to 4 high priority talkgroups and automatically switches radios to a higher priority
call, such as from a dispatcher or supervisor.
• Privacy Assures complete privacy for group and individual
calls. Other users on the system cannot monitor calls.
• Late entry Subscriber units may join a group or individual callalready in progress after powering on or upon entering thesystem coverage area.

• Normal or Automatic Site Roam (per Zone) Subscriberzones can be programmed for “Normal Channel Select,” fortraditional conventional operation, and/or “Automatic Site
Roam,” which allows subscribers to scan for site beacon
signals to lock on to in order to make or receive network calls.

• Message Trunking Users are granted access to a traffic
channel for the length of a two-way call to reduce interruptions
by utilizing fewer system resources.

• Receiver Voting Voting systems extend the portable talk-in
range of an NXR-710/810 conventional repeater by utilizing
a constellation of satellite receivers linked to the repeater site.
Portable signal strength data (RSSI) is sent via IP link to therepeater site which compares and selects the receiver sitewith the best audio quality for re-transmission.

[ Conventional System ][ Conventional IP Network ]8• System Call Queuing Stack call requests and processes calls
when a channel becomes available. System operators can assign
higher queue priority to certain users and preempt lower priority
users for more important dispatch and emergency calls.

• Beacon Signals As users roam throughout the network,
subscriber units use the beacon signals to choose the best
repeater for communications.

• Mixed Channel Type FM & NXDN conventional units canshare the same RF channel. Both subscriber units and bases
demodulate incoming analog FM or NXDN digital calls andtalkback or repeat in the same mode (combination with any
bandwidth).

NEXEDGE Gen2 employs a server-based network design with asystem controller to ensure efficient system management. The
addition of Network Manager System & Client enables
comprehensive monitoring of large-scale systems with multiple
access points. Network assets are managed using the SNMP
protocol, while IP assets are managed with a single program.
In addition to NEXEDGE server and repeater monitoring, IP asset

GPS is a widely used tool to track the position of personnel andvehicles. NEXEDGE Gen2 further enhances GPS operation tofacilitate management. The System Controller is aware at all
times how many GPS-equipped subscriber units (SUs) are on
duty, and when a new SU is registered, the controller assigns areporting frame and traffic channel.
Improvements to the air protocol minimize data overhead, maximizing traffic/data capacity while reducing GPS data processing
time.

Call Preemption/Interruption
for Consoles

Wireless Image System
This innovative system consists of a monitor station (KVT-11) anda base station (KAS-11) linked via NEXEDGE digital transceivers*.
Still images are transmitted from the remote camera to the basestation computer, which serves as the control and monitoring
center. Several sites can be monitored simultaneously.

2Supervisors and console operators – for example, in airport
control towers and taxi dispatch centers – can use this feature,
to ensure that console calls have priority. If there is no traffic
channel available, the console can take over a channel: radios
in operation will automatically stop ongoing call transmission/
reception, and the console will be able to communicate directlywith their users. Call interruption facilitates emergency alerts or
instructions to be issued to a large number of users at the sametime, making this feature also useful for public safety.

To prevent unauthorized access and/or theft of radios, the electronic serial numbers are screened by the system. When a radio
is keyed up, the ESN is constantly screened; if an unauthorized
person is trying to access the network, the operator has theoption to initiate a stun or kill to disable the radio. Preschedulingis convenient for setting up rental subscriber units. For instance,
you can set up to renew contract when a payment is made.
The radio can be disabled when the contract ends, or the radio
not being returned on a specific date. Configuration is browserbased to ensure flexibility.

This browser-based configuration tool replaces the KPG-110SM
System Manager. You can now use a PC or even mobile device tomonitor, in real time, the access status of multiple users frommultiple login points with access control. Upload a firmware
update to the System Controller for an automatic update of all
repeaters, assuring that all repeaters are constantly operating on
the latest firmware. This ensures that all repeaters on the network
will always have the latest firmware version. Log management
via the System Controller is also possible. And since this is abrowser-based approach, flexibility is assured: as long as you

applications and tough job requirements. Quality control isensured by subjecting each new model to a battery of stringent
tests before it is launched. All our products are compliant with
MIL-810 and IP54/55 weather-proofing.

The KENWOOD SOLUTION DEVELOPERS Program
welcomes experts in software and hardware
development that are interested in creating new
solutions for NEXEDGE radios and systems.
This initiative is facilitated by the KPT-110SDK
Software Development Kit.

Rugged Design to Support
Mission-critical Operations

Intrinsically Safe: Worldwide Directives/
Certifications for IS/EX Radios

Key to the development and manufacturing process, we
subject KENWOOD radios to numerous tests of durability.
Under rigorous conditions, the radios are subjected to water
immersion, temperature extremes and impact tests.
All NEXEDGE radios are both MIL-STD and IP certified.

Heavy Rain Test

FM Approvals is a certified agency authorized to
conduct internationally recognized ANSI/ISA testingfor Intrinsically Safe Apparatus. In China, CQST is asafety certification standard for electrical products to
be used in hazardous areas. USTC certification assures conformity
with relevant US and Canadian standards. CSA is the CanadianStandards Association, and also CSA US is recognized in the US.
IEC Ex is an International certification system for Ex products
Scheme. ATEX directives are EU standards for equipment to be
used where there is a potential risk from explosive atmospheres;certified products eliminate the risk of ignition and ensure safe
operation.
Note: Please read the IS Manual very carefully before using the IS radio. The radio/
battery combination must be strictly observed. There must be no substitution of items,
even if the substitute has been previously approved for use with other KENWOOD
communications equipment. Do not use the radio with any battery or accessories or
options in a hazardous atmosphere unless they are specifically certified for such use;otherwise, an explosion or fire could result. Charge batteries only in areas known to be
non-hazardous (in fresh air).

IS certified models are:
NX-200, NX-300, NX-410, NX-220, NX-320, NX-420, NX-230, NX-330;
