  1. 7th ANNUAL IEEE TECHNICAL EXCHANGE MEETING TETRA Radio Technology for the New Century Bayan A Al-Mobarak Computer & Comms Engineering Dept April 18, 2000

  2. Agenda • What is TETRA • Benefits of TETRA • Spectral Efficiency Comparisons • TETRA Network • Standards • TETRA System Deployment in Saudi Aramco • Conclusion

  3. WHAT IS TETRA? • TETRA : • TErrestrial Trunked RAdio is the latest digital mobile communications standard from the European Telecommunication Standards Institute (ETSI) • Mobile Radio open Standard • Digital Speech and Data communications • Provides high quality mobile radio communications that resolve the existing problems

  4. Benefits of TETRA • Open Standard • System Efficiency • Professional Mobile Radio (PMR) Features • Longevity

  5. Open Standard • Multiple Sourcing • System to System Roaming • Very Large Market

  6. System Efficiency • Spectral Efficiency • Full Duplex • Combined Voice and Data • Bandwidth on Demand

  7. PMR Features • Group Call • Individual Call • Telephone call • Emergency Call • Direct Mode • Priority level • Fast Call Set-Up

  8. PMR Features, Continued • Call Authorized by Dispatcher • Area Selection • Access Priority • Late Entry • Pre-emptive Priority Call • Discreet Listening

  9. Telephone Features • Call Hold • Call Completion to Busy Subscriber • Transfer of Control • Include Call

  10. Comparison of TETRA spectrum efficiency with other technologies 200kHz bandwidth 200 kHz carrier 8 channels GSM Half-rate GSM (future) 200 kHz carrier 16 channels PMR 25 kHz 25 kHz channel 8 channels / 200 kHz PMR 12.5 kHz APCO25 (US) Tetrapol 12.5 kHz channels 16 channels / 200 kHz 25 kHz carrier 4 channels / carrier 32 channels / 200 kHz TETRA

  11. Example of TETRA network VMR - Gateway External Networks PABX, ISDN, Internet etc. DC SwMi: Switching and Management infrastructure SCN: Switching and Control Node NMS: Network Management System DC: Dispatch Console BS; Base station VMR:Vehicular Mounted Radio HPR: Hand-portable Radio Central Logging Recorder NMS SwMi BS HPR

  12. TETRA Standards Other TETRA Network PABX, PSTN, ISDN, PDN Voice And Data ISI Direct Mode Gateway AI TETRA Network PEI Mobile Stations TSI

  13. TETRA System Deployment in Saudi Aramco • The new system will enhance the following: • Network congestion • up to date technology feature • Improve quality • Interference • Overcome the discontinued manufacturers support

  14. Conclusions • TETRA is the technology that will take the radio professional users to the new millennium • Interoperability testing is creating real competition • TETRA provides the demanding multimedia services needed now and the future • Data applications offer concrete benefits • Completely secure networks can be made with TETRA
