1. November 20021 TETRA Release 2 Overview Mark Edwards Principal Staff Engineer Motorola European System Design Centre

2. November 05 - TETRA World Congress 2005 TWC2005 – November 2005 Does TETRA1 handle data? Database look up AVL Email File transfer Limited slow scan video But some multimedia applications could ask for more….

3. November 05 - TETRA World Congress 2005 TWC2005 – November 2005 Mission Critical Data Applications on TETRA Today’s applications need data capacity –Frequent messages, small payload: AVLS from portables and vehicles Database access Status messaging But some applications starting to need more data throughput –Less frequent messages, much bigger payloads Mug shots File transfer Slow scan video TETRA Single Slot Packet Data TETRA Multi Slot Packet Data

4. November 05 - TETRA World Congress 2005 TWC2005 – November 2005 TETRA2 brings new capabilities … to Fire Check floor plans of burning building TETRA 1 Database of plans held on local CD in cab TETRA 2 Updated plans can be downloaded as appliance is en route Fire fighters get latest information Check database of hazardous chemicals TETRA 1 Text based results from database search TETRA 2 Text and image results from database search Fire fighters get clearer information Fire fighters get clearer information

5. November 05 - TETRA World Congress 2005 TWC2005 – November 2005 TETRA2 brings new capabilities … to Ambulance Transmit an ECG trace from ambulance to doctor in hospital TETRA 1 Transmit compressed ECG TETRA 2 Less compression used means more details on ECG More accurate diagnostic for heart conditions Transmit pictures from scene so doctors can predict injury TETRA 1 still images or slow scan video TETRA 2 More detailed video image Doctors can make more accurate predictions

6. November 05 - TETRA World Congress 2005 TWC2005 – November 2005 Other Additional Applications of TETRA 2 TETRA 2 Data Application User BenefitsPolice Full mobile dispatch, extending complete control room environment to the field Greater local control at a major incident site Transport Live updates of arrival/departures boards at bus stops More relevant and accurate information to passengers Check image database to see manifests, passenger lists etc Helps reduce smuggling of goods and people Oil, Gas & Utilities Camera monitoring at very remote locations to check on lone workers Increased safety for remote workers Camera monitoring of areas at risk - used to supplement telemetry data Faster and more accurate understanding of events

7. TETRA2 TEDS (TETRA Enhanced Data Services) – High Speed Packet Data for TETRA

8. November 05 - TETRA World Congress 2005 TWC2005 – November 2005 TETRA Enhanced Data Service - TEDS Backward compatible with TETRA Release 1 –Network integration capability Flexible data rates and spectrum use –25, 50, 100 and 150 kHz channels bandwidths –Can trade off data rate, spectrum and range Integrated TETRA 1 and TEDS system –i.e. can receive TETRA 1 calls on TEDS channels Technology selected for TEDS use –Multi-carrier QAM (Quadrature Amplitude Modulation) in all bands –D8PSK in 25 kHz High speed packet data service for TETRA enabling faster data rate and higher data capacity

9. November 05 - TETRA World Congress 2005 TWC2005 – November 2005 High Speed Packet Data Deployment TEDS will be the solution for mission critical A range of channel bandwidths available in the standard –Offer a single TEDS channel at each site, in addition to TETRA 1 voice channels –Provision channel bandwidth based on number of users and their data application requirements The modulation scheme can adapt to radio transmission conditions

10. November 05 - TETRA World Congress 2005 TWC2005 – November 2005 GPRS versus TETRA - Availability GPRS constraintsTETRA 2 benefits Availability At times of high voice load there is little or no GPRS service available –Revenue streams and profit targets dictate data coverage and capacity –GSM cells often provisioned with dynamic GPRS channels to give priority to lucrative voice services Users get the level of data service they need –End user requirements dictate the coverage and capacity in their own private network –TETRA cells are provisioned with the data capacity to meet end user’s operational needs

11. November 05 - TETRA World Congress 2005 TWC2005 – November 2005 GPRS versus TETRA - Predictability GPRS constraintsTETRA 2 benefits Predictability GPRS users often see lower throughputs than today’s TETRA packet data users –GPRS Data bandwidth is shared between many public users TETRA users get access to the high bandwidths offered by the standard –TETRA data bandwidth is shared only with users on a private network

12. November 05 - TETRA World Congress 2005 TWC2005 – November 2005 GPRS versus TETRA - Security GPRS constraintsTETRA 2 benefits Security Meets commercial security requirements Meets Government security requirements, e.g. –Mutual authentication –Longer keylengths means much harder to decrypt TETRA: Availability – Predictability - Security

13. November 05 - TETRA World Congress 2005 TWC2005 – November 2005 Typical upgrade to TETRA2 Requirements from all users…. Maintain GoS (Grade of Service) for voice and any legacy data services Increase capacity for new data services Easy upgrade Your expectations for TETRA2

14. November 05 - TETRA World Congress 2005 TWC2005 – November 2005 Things to Remember New Spectrum –Maintain present spectrum to keep GoS for existing voice & data services New Terminals for TEDS services –Retain present terminals for existing voice & data services In partnership for TETRA2

15. November 05 - TETRA World Congress 2005 TWC2005 – November 2005 Spectrum: Progress has been made….. ECC (Electronic Communications Committee) has just approved a Work Item to add support for Wideband technologies in 385MHz – 470 MHz –385 MHz – 390 MHz –385 MHz – 390 MHz would be the ideal choice for TETRA 2 –reserved for Nato –Sporadically used at present –users need to be very influential National regulators are responsible for allocating spectrum –Will Consider the local operating environment –Will Balance requirements from public safety, transportation, etc. Users need to exert their influence through the MOU and directly to their National regulators

16. November 05 - TETRA World Congress 2005 TWC2005 – November 2005 TETRA 2 takes the lead The facts of life: If you already have TETRA you will still be able to use existing: –Terminals –Application –Services When you get TETRA 2 you gain: –Data speed & capacity –New multi media applications –Increased operational efficiency –New possibility to innovate

17. November 05 - TETRA World Congress 2005 TWC2005 – November 2005 High Speed Data You can rely on Accessible Available Secure Predictable Alway s on Alway s there Alway s Fast Alway s Safe Added by TETRA and TEDS
