  1. Current developments in TETRA K.-H. (Charly) Hengevoß Board Member TETRA MoU Association Rohill Engineering B.V.

  2. Fire Exits

  3. Agenda • TETRA – The living standard • How to interconnect two TETRA systems • TETRA Release 2 is more than TEDS... • TETRA Release 2 – A world filled with applications • The future beyond TETRA Release 2

  4. The living standard • Standardisation started in the late 80s • First version of air interface specification ETSI ETS 300 392-2 ed 1 published in March 1996 • First nationwide TETRA public safety network completed in 2002 • TETRA Association formed in 1995 • First IOP Test certificates in 1999 • Core document for TETRA Release 2, the ETSI EN 300 392-2 V 3.1.1, published in 09/2006

  5. How to interconnect two TETRA systems • European integration includes cross-border police co-operation • Specification for harmonised radio anddata communication • ETSI standard TETRA satisfies keySchengen requirements • EU decision to conduct a pilot testprogramme

  6. Three-Country Pilot    • National sub-networks were connected in June 2003 • First tests of cross-border communications in October/November 2002 • Practical test with police forces, fire brigades, rescue services, customs and civil protection carried out in May/June 2003 • Final report published inNovember 2003 • http://www.3countrypilot.com

  7. Does TETRA handle data? • Database look up • AVL • Email • Data transmission • Limited slow scan video • But multimedia applicationsare more difficult...

  8. Evolution: Application vs. TETRA today Not suitable Suitable Effektive

  9. Mission critical data applications with TETRA • Current applications require data transmission capacity • Frequent messages, small payload • GPS position data from portables and vehicles • Database requests • Status messaging • But some applications require higher data throughput • Infrequent messages, much higher payload • Picture of a wanted person • File transfer • Slow scan video TETRA Single Slot Packet Data TETRA Multi Slot Packet Data

  10. 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 systems - i.e. Can receive TETRA 1 calls on TEDS channels • Technology selected for TEDS use- Multi-carrier QAM (Quadrature Amplitude Modulation) in all bandwidths - D8PSK in 25 kHz

  11. Gross data transmission rates for QAM

  12. How do data, range, bandwidth vary? 600 kb/s FramingRate 500 kb/s 150 kHz 400 kb/s Modulation scheme 64QAM 16QAM 4QAM D8PSK (25 kHz) 300 kb/s 100 kHz 200 kb/s 50 kHz 100 kb/s 25 kHz Range (km)

  13. How does this compare with TETRA 1? 600 kb/s FramingRate 500 kb/s 150 kHz 400 kb/s Modulation scheme 64QAM 16QAM 4QAM D8PSK (25 kHz) 300 kb/s 100 kHz 200 kb/s 50 kHz 100 kb/s 25 kHz Range (km) TETRA 1

  14. The Power of TETRA Release 2 TETRA 1 + TETRA 2 at 25 kHz TETRA 2 at 150 kHz TETRA 2 at 50 kHz TETRA 2 at 100 kHz TETRA 2 at 100 kHz TETRA 2 at 50 kHz TETRA 2 at 150 kHz Legend: Circle size = coverage area Circle height = data capacity All TETRA 2 sites include TETRA 1

  15. The news in TETRA Release 2 • New speech codec • USIM requirement for TETRA • Interworking and Roaming with other networks „3G“ • Enhancement of the air interface • Extension of operating range of TETRA • Support for further requirements (e.g. location information)

  16. TETRA Release 2 brings newcapabilities to fire • Floorplans of burning buildings • TETRA 1 • Database of plans held on CD in cab • TETRA 2 • Updated plans can be downloaded as appliance is on 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

  17. TETRA Release 2 brings newcapabilities to Ambulance • Transmit ECG trace from ambulance to doctor • in hospital • TETRA 1 • Transmit compressed ECG • TETRA 2 • Less compression means more details on ECG • More accurate diagnostic for rare heart conditions • Transmit pictures from crash scene • TETRA 1 • Still images or slow scan video • TETRA 2 • More detailed video images • Doctors can make more accurate predictions

  18. Status of TETRA Release 2 • Core document EN 300 392 – 2 v 3.1.1 has been delivered 20.09.2006. • Work on related aspects as e.g. PEI almost completed • European Regulators working on frequency allocation • Manufacturers started development • 27th/28th March 2007 a user/manufacturer workshop on prioritising the introduction takes place in Bonn

  19. The future beyond TETRA Release 2 • Intention to describe and define functional and operational user requirements, capabilities, applications and scenarios beyond 2015 • Activities towards globalisation of future telecommunications standardisation work - Transfer of ETSI Project DAWS to the European- American joint project MESA connected with TIA’s APCO Project 25/34 • Increasing the transparency in patents and licences - ETSI revised its own „Patent Policy“ to meet future requirements
