Andrea Festelli Marconi Mobile

2 Agenda TETRA and public cellular systems Comparison with other PMR technologies TETRA market State-of-the-art technology The future

3 Frequently Asked Questions
Why do I need TETRA instead of public cellular networks (GSM, GSM-R, UMTS)? Why do you say that TETRA is the winning PMR technology? Is TETRA a mature technology? Which are the relations between TETRA and UMTS? ? ? ? ?

4 !

5 Group communications Point-to-multipoint voice and data including many supporting features such as Unlimited number of included users Unlimited site extension Dynamic Group Number Assignment (DGNA) Late entry Talking party identification ...

6 Control room and dispatching operations
Focus on communications between radio terminals and control room/dispatcher operators Call Authorised by Dispatcher (CAD) Ambience/Discreet listening Dynamic services management ...

7 Secure communications
Multiple security schemes and algorithms Authentication of User / Terminal Authentication of the Infrastructure Encryption: Air Interface Encryption End-to-End Encryption OTAR- Over The Air Re-keying Security Management Disabling of stolen radios This is very confidential!

8 Communicate also when out of network radio coverage
Fully digital trunked (TMO) and direct (DMO) modes of operation Dual watch Repeater Gateway DMO adds fringe or out of coverage area communications DMO provides communications within coverage at times of capacity limitations

9 And the professional mobile specific features continue
Emergency calls Fast call set-up Concurrent voice and data “Real time” short data services including status messages Further PMR supplementary services: call priority, access priority, area selection, ...

10 TETRA features differentiation from public networks
GSM/GSM-R UMTS Features Group/Broadcast Call Dynamic Group Number Assignment Call authorized by dispatcher Ambience and Discreet listening Authentication of the Infrastructure End-to-end encryption OTAR Physical disabling of stolen radios Direct Mode DMO Gateway/Repeater Fast Call Set-up Emergency calls (preemptive) Short Data Service Packet Mode Data Circuit Mode Data Concurrent Voice & Data Bit-rate on Demand Priority calls  (real time)  GSM-R with limitations -  GPRS - ?

11 TETRA and other PMR technologies
TETRA is: Digital TDMA based Open standard

12 Digital vs. analogue Constant voice quality Higher data rates Efficient and effective secure communications and authentication

13 TDMA vs FDMA TDMA FDMA CH 1 CH 2 C H 1 C H 2 C H 3 C H 4 Spectrum kHz
25 CH 1 C H 1 C H 2 C H 3 C H 4 Carrier 1 12.5 Carrier 1 CH 2 Carrier 2 To Time To FDMA TDMA

14 TDMA vs FDMA Bitrate on demand Higher data rates Simultaneous voice and data Simplex terminal for duplex communications One TRX to manage four traffic channels

15 TETRA is a real open standard
TErrestrial Trunked RAdio (TETRA) is an open standard which is defined by the ETSI to meet the needs of the most demanding professional mobile radio users. It has been fully accepted by all the European and many other Administrations. ETSI has started the work program for TETRA release 2

16 Interoperability certification
The Interoperability Certificate (IOP) assures that various manufacturers infrastructure and terminals can indistinctly operate on any TETRA network The various functionality tested and approved are summarized in public tables Tests are executed by an independent accredited test house: up to now Teledanmark (Danish operator)

17 TETRA and APCO 25 Project 25 is a Digital Radio Project that involves both APCO and TIA members, in ANSI/TIA Standardisation Project 25 Phase 1 is 12.5kHz FDMA Phase 2 has FDMA (6.25 kHz) and TDMA (12.5 and 25 kHz) components TETRA has been selected early in 2000 as TDMA option for the phase 2 (IMBE codec and DES encryption) APCO 25 and TETRA are the only two digital standards for PMR originated from international standardisation institutes that are being deployed across the world

19 Truly multi-vendor technology
Currently: 10 independent manufacturers of TETRA network infrastructure 7 independent manufacturers of TETRA terminals

20 Competition benefits Competitive prices Competitive quality Innovative products and solutions Wide choice of products and Applications Developers

21 PMR market trends The Worldwide Digital Radio Installed Base
(excluding iDEN) - 1st January 2001 3% 14% 36% TETRAPOL APCO25 18% EDACS TETRA 29% Other Source: IMS - June 2001 Total value of TETRA awarded contracts worldwide exceeds 2800 US$m

23 Who buys TETRA? Worldwide Tetra awarded contracts by segment
Update 10/2001 (total value over 2800 US$m) 2% 1% 3% 17% 39% Public safety Public access Transport Military 38% Utilities Local government Source: Marconi internal info

24 Public safety and security services
Customer trends Public safety and security services EUROPE: TETRA is the consolidated open standard technology for PSS radio mobile systems. Almost all European Countries are using (or have plans to use) TETRA WORLD WIDE: interest is consistently increasing and first projects are starting in all regions Transport and utilities (Civil Users) Projects in this segment partially suffered the spectrum issues for civil TETRA in the past but the solution to these problems is on the way

25 TETRA growth outside Europe: China
On April 2001 TETRA has been adopted as national standard by Chinese administration. Most of the allocated radio channels are in the 800MHz frequency band First tenders for TETRA have already been issued and assigned for transport (railways and subway companies) and public safety applications TETRA market growth is envisaged for a long duration in China

26 TETRA growth outside Europe: USA
TETRA adopted as basis of a 4-slot TDMA system for Project 25 Phase II MOU proposal includes use of DVSI IMBE codec, DES encryption and Phase I FDMA interoperability TR-8 formulating committee (TR-8.14) established to develop ANSI/TIA standard TR-8.14 is working on two variants: Standard for Public Safety with changes Standard for Non Public Safety without changes to codec or encryption Shell Standards in draft form, with ongoing work, to complete during 2001 North American TETRA Forum set up, providing support from users

27 TETRA is state-of-the-art

28 WAP and Bluetooth on TETRA
Network Management Center Content Provider WAP Terminal IP WAP GW Internet Database LAN Server IP WAP Server IP Corporate Intranet Switching/ RoutingNetwork IP IP GPS Bluetooth Control Room Server IP TETRA Infrastructure IP Voice/IP Dispatcher

29 TETRA release 2 is the answer
The future UMTS is the future of cellular systems TETRA is the future of PMR systems TETRA and UMTS are complementary and will offer integrated services: TETRA release 2 is the answer
