2 Spectrum Efficient Meets FCC mandates today & tomorrow
NXDN Protocol (framing, sync, control data, vocoder payload, FEC) Digital voice sent at 4800/9600 bps signal rate Supports 60,000 Unit IDs (UID), 60,000 Group IDs (GID) DVSI AMBE+2 TM VOCODER (digitizes analog voice; aka codec) Half-rate 3600 bps (6.25 or 12.5 kHz NXDN) Full-rate 7200 bps (12.5 kHz NXDN- available 2010) 4-Level FSK Modulation (4LFSK) Carrier is shifted ± the center freq at 4 predetermined values (“offsets”) ±2400 Hz & ± 800 Hz (12.5 kHz) ±1050 Hz & ±350 Hz (6.25 kHz) Each offset represents 2 bits of binary (“dibit symbol”) 4800 bps: 2400 symbols/sec 9600 bps: 4800 symbols/sec (available 2010) FDMA (Frequency Division Multiple Access) Users accesses spectrum via the frequency domain One user occupies one frequency 1 Voice path Per Channel Emissions FCC compliant: 12.5 kHz Narrow Channel Operation 6.25 KHz Very Narrow Channel Operation Spectrum Efficient Meets FCC mandates today & tomorrow Analog: 25 & 12.5 kHz Channels NXDN® Digital: 12.5 & 6.25 kHz Channels l Copyright © 2005 KENWOOD All rights reserved.

4 Spectrum Efficient FCC Certified Emissions
New licenses: Apply for analog, 12.5 NXDN and/or 6.25 NXDN emissions Modify existing licenses: Add 12.5 NXDN and/or 6.25 NXDN emissions No current FCC mandate for 6.25 kHz ! Copyright © 2005 KENWOOD All rights reserved. May not be copied or reprinted without prior written approval.

5 NXDN ® Voice Delay Voice digitization adds some time delay TDMA is timed slot based - adds more delay Result : NXDN FDMA has less voice delay than TDMA NXDN ® Superior Audio AMBE+2: Improved FEC, Noise Reduction & AGC (vs. IMBE) Performs under degraded / noisy conditions Adopted for P25 NXDN 6.25/12.5: AMBE+2 Half Rate P25 Phase I (orig.): IMBE Full Rate Phase I (8/08): AMBE+2 Full Rate Phase II: AMBE+2 Half Rate Source: DVSI Inc., USA Copyright © 2005 KENWOOD All rights reserved.

Best Bit Error Rate (BER: “digital signal quality”) NXDN ® outperforms P25 Phase I Reason: DSP Filtering, Offsets & FEC Copyright © 2005 KENWOOD All rights reserved. May not be copied or reprinted without prior written approval.

7 NXDN ® : Increased Range
Signal Strength varies with distance from transmitter Signal strength at any given distance is the same for both analog & digital Analog vs. Digital Audio Quality varies with signal strength esp. at weaker signal strengths Analog audio: Increased background noise; repeat transmissions common Digital audio: Corrected for noise & intelligibility restored (AMBE+2 FEC & speech replication algorithms ) Digital audio user perception is better than analog at weak signal strengths Analog vs. NXDN ™ PESQ test results (measured per ITU P.862 standard) NXDN ® : Increased Range RF Signal Strength vs. Distance = Same for analog & digital signals Audio Quality varies with signal strength (PESQ ITU P.862): low signal: Increased noise NXDN @ low signal: Error corrected & intelligibility restored Copyright © 2005 KENWOOD All rights reserved.

10 Trunked Mode 3,000 GID’S & 3,000 UID’S Per Site
Large ID capacity for multiple organizations Talk groups GIDs organized by regions, departments, special operations, etc. Individual UIDs provides caller ID & private call Assignable UID & GID range: 1- 65,619 System Busy Call Queuing / 8 Priority Levels Calls are assigned a traffic channel based on importance Supervisors, administrators, dispatchers can have priority access Emergency Calls are always highest priority ( Level1) All Traffic Channels busy: call requests are queued based on priority level (UID COS). As Traffic Channels become available, highest priority PTT caller is granted access. System Busy Call Queuing / Pre-emption Higher priority calls will remove lower priority calls in progress For dispatcher, supervisors, emergencies Message Trunked mode only (pre-emption cancels call hold timer; current caller must release PTT for traffic channel to be assigned to preemptor) Copyright © 2005 KENWOOD All rights reserved.
