EFFICIENT USE OF THE RADIO CHANNELS • Conventional network – radio channels are dedicated to users or types of communications Queue • The MC 9600 trunked network – radio channels are multipurpose and dynamically allocated Channels Free Channel Andy Mc. Gregor Free Channel Queue A Company Associated with Nortel Networks Free Channel RABC PS s/c 10 October 2002 - 14

SHARED SYSTEMS • Split the capital expenditures while getting a better system • Split the running costs • Benefit from economies of scale • Facilitate inter-agency communications Each hosted organisation wants to keep – Operational and tactical independence – Confidentiality – System availability ð As if using their own dedicated system Andy Mc. Gregor A Company Associated with Nortel Networks RABC PS s/c 10 October 2002 - 15

Spectrum efficiency • European Radiocommunications Committee (ERC) : Methodology for the assessment of PMR systems in terms of spectrum efficiency, operation and implementation - Bucharest, December 1997 – – – TETRAPOL 10 k. Hz: TETRAPOL 12. 5 k. Hz: TETRA (50% DMO, 50% V+D): EDACS 12. 5 k. Hz: EDACS 25 k. HZ: 3. 3 2. 6 2. 3 2. 1 1. 5 • French Ministry of Interior for ACROPOL case in Paris, necessary bandwidth for same communications requirements: – TETRAPOL: 1. 41 MHz – TETRA: 2. 725 MHz Andy Mc. Gregor A Company Associated with Nortel Networks RABC PS s/c 10 October 2002 - 16

EFFICIENT DIGITAL MODULATION & DEMODULATION • GMSK - Constant envelope – Simple, efficient and "clean" power amplifiers • Coherent demodulation – Lower error rate = enhanced sensitivity • Low impact of inter-symbol interference (urban/hilly terrain) – No channel equalisation = simpler receivers – Easy implementation of simulcast Andy Mc. Gregor A Company Associated with Nortel Networks RABC PS s/c 10 October 2002 - 17

ENHANCED RADIO COVERAGE • Outstanding sensitivity : -121 d. Bm – coherent demodulation – channel coding – non- transparent base stations - 121 d. Bm TETRAPOL vs typical competing solutions • Antenna diversity technique (BS) – additional gain on the inbound link – higher range for handheld radios - 113 d. Bm TETRAPOL can halve the number of radio sites Andy Mc. Gregor A Company Associated with Nortel Networks RABC PS s/c 10 October 2002 - 18

A SPECTRUM-EFFICIENT SOLUTION • Spectrum efficiency from combination of: –reuse pattern, coverage performances vs type of calls, trunking, spectral characteristics, simulcast capabilities, . . . Typical competing systems C/I > 19 d. B 19 cell reuse pattern MC 9600 C/I = 15 d. B 12 cell reuse pattern The MC 9600 can triple spectrum capacities compared to existing 25 k. Hz analog solutions Andy Mc. Gregor A Company Associated with Nortel Networks RABC PS s/c 10 October 2002 - 19

SIMULCAST : AN EFFICIENT OPTION FOR WIDE-AREA GROUP CALLS Wide-area goup calls Simulcast coverage Spectrum requirements: 1 channel (ex. : 12. 5 k. Hz) Cellular coverage Spectrum requirements: 1 channel x n cells (ex. : 10 x 25 = 250 k. Hz) Spectrum requirements can be minimum Andy Mc. Gregor A Company Associated with Nortel Networks RABC PS s/c 10 October 2002 - 20

BENEFITS OF FDMA TO DIRECT MODE • Simple and reliable – No engineering issues linked to multi-slot synchronisation constraints • Spectrum-efficient – 12. 5 k. Hz only (incl. Repeater Mode) • Smooth analog-to-digital conversion – Existing 12. 5 k. Hz Direct Mode channels can be used – Analog and MC 9600 radios can use the same DM channels Smart solution for a vital communication mode Andy Mc. Gregor A Company Associated with Nortel Networks RABC PS s/c 10 October 2002 - 21

SMOOTH CONVERSION OF 12. 5 k. Hz ANALOG CHANNELS • Simple swap of an analog repeater for a digital one on the same frequency – Already-allocated channels can be used : no need to ask for new channels or refarm the radio spectrum • Conversion can be planned on a geographical basis, on a per-organisation basis and on a per-channel basis – Highly gradual and flexible conversion • Peaceful coexistence between the old and the new system – The two systems can run in parallel as long as required Andy Mc. Gregor A Company Associated with Nortel Networks RABC PS s/c 10 October 2002 - 22

HIGH-PERFORMING VOCODER • • • RP-CELP technology 6 kbps Excellent speaker recognition High audio quality High performances in noisy environments (engines, sirens, riots, . . . ) • Language / accent-independent • Low processing power requirements Andy Mc. Gregor A Company Associated with Nortel Networks RABC PS s/c 10 October 2002 - 23

ROBUST CHANNEL CODING • Sophisticated error control techniques (FEC*) – Interleaving, block coding, cyclic coding, . . . • • Non-transparent packet data transmission Non-transparent base stations Intrinsic robustness of the modulation Outstanding results: residual BER better than 10 -8 TETRAPOL is reliable in good and bad radio conditio Andy Mc. Gregor A Company Associated with Nortel Networks RABC PS s/c 10 October 2002 - 24

VOICE AND DATA ON THE SAME PLATFORM • 1 radio terminal instead of 2 – Harmonised installed base: easy swapping of terminals – Users are not anymore overloaded with equipment • Automatic channel allocation (trunking) – Users do not have to switch between voice and data systems Andy Mc. Gregor A Company Associated with Nortel Networks RABC PS s/c 10 October 2002 - 25
