Spectrum Efficient

• NEXEDGETM Equipment- Ready Today & Tomorrow– FM Analog @ 25 & 12.5 kHz Channels– NXDN™ Digital @ 12.5 & 6.25 kHz Channels– Compliant with current frequency assignments– Easily converts to very narrow bandwidths in the future


NXDN™ Digital Air Interface

• FDMA (Frequency Division Multiple Access)– Users accesses spectrum via the frequency domain– One user occupies one frequency (1 voice path @ channel)

• NXDN™ – Created with optimized DSP coding, AMBE+2™ VOCODER, unique filtering/offsets– 4-Level FSK modulation technique– 4800 bps signal rate (operates on very narrow 6.25 & narrow 12.5 kHz channels)– 9600 bps signal rate (operates on narrow 12.5 kHz channels only) - Available 2010



• Natural Sounding Digital Voice– AMBE+2™ VOCODER - state of the art voice digitization technology – Replicates natural human speech nuances accurately unlike early technologies– Offer’s superior voice quality at varying signal strengths even at highway speeds

• 20 % or Better Range Than FM – FM analog reception becomes increasingly noisier and intermittent in fringe areas – NXDN’s low BER improves reception in fringe areas– Increases effective range as much as twenty percent over FM

Digital Trunked Mode



• NEXEDGETM Digital Trunking– Faster access / Less user operation required than conventional systems

– Increased call capacity via trunked efficiency

– Enhanced calling capabilities

– System access privileges and improved security

Ethernet Switch Repeat Operation

Simplex TA (Conventional NXDN or FM Channel)



• Fast System Access– Automatic channel selection. No user monitoring is required

• Enhanced Efficiency– Users share a pool of channels per site– Experiences less busies during peak hours

• Up to 30 Channels @ Site– Sites can be configured from two to 30 channel for full trunked efficiency.

Ethernet Switch



• Transmission Trunking – A Traffic Channel (TC) is acquired every PTT. The TC is released upon PTT

release.– Benefit: Frees system resources between PTT exchanges for other users– Trade-off: Two-way conversations may be interrupted by temporary system busies.

• Message Trunking– A TC is acquired on the initial PTT and held after PTT release for called units to

respond. If no activity is detected during a programmed hold time, the TC is released.

– Benefit: Uninterrupted two-way conversations.– Trade-off: Less system resources are available to other calls.

Ethernet Switch



• 3,000 GID’S: Large talk group capacity for fleet dispatch operations.• 3,000 UID’S: Large unit ID capacity for private unit-to-unit calling.

• Call Queuing– System can automatically put calls in a queue when all Traffic Channels are busy – Calls are processed when a traffic channel becomes available

• 8 Priority Levels with Pre-emption– Processes calls queue in order of priority (UID COS). – Pre-emption re-allocates a talk channel for high priority calls (e.g. dispatcher, supervisor,

emergencies).

Ethernet Switch



• Group Calls: Talk Group calling for fleets, sub-fleets & dispatch operations• Individual Calls: Private unit-to-unit calling

SIMPLE CALL OPERATION



• Priority Monitor ID 1 & 2 – Automatically collects subscriber units to a high priority GID call (e.g. dispatcher, supervisor) even if on a low priority GID call.

• Late Entry- Permits subscriber units to join a call already in progress after powering on or entering system coverage.

• Broadcast Call- A “one-way call” to a GID talk group for priority alerts and emergencies in which units cannot respond (select target GID, Press BC key, Press PTT, the GID is BC called).

Ethernet Switch



• Fail Soft Mode* - If trunking capability is disabled, the control channel reverts to conventional operation so basic communications can continue.

• Control Channel & Traffic Channel Switching– If a CC logic unit is disabled the system automatically assigns a TC as a new CC – If a TC logic unit is disabled the system automatically removes it from service.

• Remote GID Add* (PC Serial control)– Adds a new GID to subscribers remotely over-the-air– Form a workgroup for emergencies, mutual aid, and special events, operations or incidents.– A reset operation can delete the GID over-the-air

Ethernet Switch

• 60,000 GID’s & 60,000 UID’s @ Network– Large total capacity for shared networks and large fleets.

• Automatic Roaming – Subscriber units automatically search for the best sites while moving throughout

a network.

– Accurate roaming and registration decisions are based on control channel hunt algorithms, RF signal strength (RSSI) and digital signal quality (BER).

• ESN Validation– Unique factory embedded Electronic Serial Number validated by the system to

protect against unauthorized access (validated at registration)

IP



• Individual Call Response– On an Individual Call, the system waits for the called party to answer

before allocating a Traffic Channel to the call (saves network resources).

• Busy System Wait – On a Group Call, the system waits for free Traffic channels at all target

sites to proceed with call (best effort for all units to receive the call).
