  1. Review of ITU-R Study Group Activities Kevin A. Hughes Radiocommunication Bureau

  2. ITU-R objective • “…to ensure rational, equitable, efficient and economical use of the spectrum by all services, …… • …to carry out studies and adopt Recommendations on radiocommunication matters”

  3. ITU-R objective Objective achieved through (inter alia): • World (and Regional) Radiocommunication Conferences • Approval of Recommendations Technical studies are required which are conducted in Study Groups

  4. ITU-R Study Groups • Groups of experts from ITU membership • Draft technical bases for WRCs (and RRCs) • Draft Recommendations • technical characteristics • operational procedures • Compile Handbooks

  5. Study Groups • SG 1: Spectrum management • SG 3: Radiowave propagation • SG 4: Fixed-satellite service • SG 6: Broadcasting service • SG 7: Science services • SG 8: Mobile services • SG 9: Fixed service

  6. ITU-R Study Groups • Currently 7 Study Groups • Subordinate groups • Working Party • Task Group • Rapporteur Group • Joint ……. • Coordination Committee for Vocabulary • Special Committee (regulatory/procedural) • CPM - Conference Preparatory Meeting

  7. Scope of Study Group 1(Spectrum management) • Principles and techniques for • spectrum management • sharing criteria and methods • spectrum monitoring • long-term strategies for spectrum utilization • Inter-service sharing and compatibility

  8. SG 1- some key areas of study - • Unwanted emissions • out-of-band (OOB) and spurious emission domains • protection of safety and passive services • Spectrum management methodologies • long-term planning for national SM • economic approaches • Handbooks • Spectrum monitoring • National spectrum management

  9. Scope of Study Group 3(Radiowave propagation) Propagation of radiowaves in ionized and non-ionized media and the characteristics of radio noise, for the purpose of improving radiocommunication systems

  10. SG 3- some key areas of study - • Global mapping of radiometeorological parameters • rain intensity, water vapour density • refractivity • Prediction procedures • interference and coordination • Earth-satellite paths • short-range communications (personal, LANs) • terrestrial broadcasting and mobile services

  11. Scope of Study Group 4(Fixed-satellite service) Systems and networks for the FSS and inter-satellite links (in the FSS), including associated tracking, telemetry and telecommand functions

  12. SG 4- some key areas of study - • Sharing between non-GSO FSS systems and other FSS networks • mitigation techniques for sharing between • non-GSO/FSS systems and other networks using the GSO • non-GSO FSS systems • IP over satellite • WRC-03 issues • e.g. protection of MSS feeder links at 5 GHz

  13. Scope of Study Group 6(Broadcasting service) Radiocommunication broadcasting (terrestrial and satellite) of vision, sound, multimedia and data services primarily intended for delivery to the general public

  14. SG 6- some key areas of study - • Digital sound broadcasting below 30 MHz • system specification (Rec. BS.1514-1) • planning parameters (DNR) • Studies relating to revised b’cast satellite plans (Appendices 30 and 30A) • sharing criteria between BSS, FSS and terrestrial services • Guidelines for system options for digital terrestrial TV b’casting

  15. SG 6- some key areas of study (continued) - • Coverage prediction methods and evaluation of DTTB systems • Protection of b’cast systems against radiation by wired systems, ISM equipment and short-range devices

  16. Scope of Study Group 7(Science services) • Systems for space operation, space research, Earth exploration and meteorology • Radio astronomy • Standard frequency and time signals

  17. SG 7- some key areas of study - • Allocations for space science services • space operations and space research services • precipitation radars (~ 35 GHz) • Earth exploration satellite service (420-470 MHz) • Radio astronomy • protection criteria

  18. Scope of Study Group 8(Mobile services) Systems and networks for the mobile, radiodetermination and amateur services, including related satellite services

  19. SG 8- some key areas of study - • IMT-2000 • update radio interface specs. • global spectrum harmonization • systems beyond IMT-2000 • PPDR (Public Protection and Disaster Relief) • identification of spectrum • Draft New Report on objectives and requirements for PPDR

  20. SG 8- some key areas of study (continued) - • ITS (Intelligent Transportation Systems) • standards for Vehicle Information and Communication Systems (VICS) • evolution of Dedicated Short Range Communication (DSRC) systems • RLANs (Nomadic Wireless Access) • broadband NWA (frequency spectrum and standards harmonization)

  21. Scope of Study Group 9(Fixed service) Systems and networks of the fixed service operating via terrestrial stations

  22. SG 9- some key areas of study - • High altitude platform stations (HAPS) • additional allocations in range 18-32 GHz • technical and operational characteristics • impact on other services • interference mitigation techniques • Frequency bands for High Density systems in FSS • above about 19 GHz • Handbooks • Frequency adaptive systems at MF/HF • Fixed Wireless Access

  23. Joint Studies • Joint Task Group (JTG) 4-7-8-9 5 GHz band allocations • WRC-03 AI 1.5 • Resolution 736 (WRC-2000) • JTG 4-7-8 Sharing in band 13.75-14 GHz • WRC-03 AI 1.24 • Resolution 733 (WRC-2000)

  24. Study Group Products • Technical bases for WRC • CPM Report • Draft ITU-R Recommendations • Handbooks

  25. CPM Report to WRC-03 • Radionavigation, radnav-sat and radiolocation services • Mobile, mob-satellite and space science services • Fixed-satellite and broadcast-sat services • Fixed and fixed-sat services and HAPS • Maritime-mobile, amateur and am-sat, and b’cast services at MF and HF • Other matters • Future work programme

  26. ITU-R Recommendations • > 900 Recommendations in 16 series • “Standards” in areas of spectrum management and radio technology • Result of consensus from meetings of world-wide experts • Some referred to in RR • Used by spectrum planners and system designers

  27. ITU-R Handbooks • Over 30 published • Tutorial in nature • Emphasis on use by developing countries • Liaison with ITU-D (and ITU-T) • Continuing Handbook programme in ITU-R

  28. Concluding remarks • The Study Groups represent a major aspect of ITU-R activities • Technical forum for discussion amongst experts • Technical bases for Radio Conferences • Recommendations and Handbooks
