  1. An Introduction to the ITU Kevin A. Hughes Radiocommunication Bureau

  2. The ITU(International Telecommunication Union) • Founded in 1865 • “… is an international organisation within which governments and the private sector coordinate global telecommunication networks and services” • Foundation for today’s radiocommunications services

  3. Roles of ITU • Regulation • spectrum management and coordination • Radio Regulations • Standardisation • ITU Recommendations • seamless interworking of systems on a global basis • technical characteristics/specifications, operational procedures, “best” practices • Development • assistance to developing countries • improving telecoms infrastructure in the developing world • catalyst for forging development partnerships • increasing awareness of today’s technologies

  4. ITU Membership • ITU founded on principle of cooperation between governments and the private sector • Membership encompasses: • telecoms policy makers • regulators • network operators • equipment manufacturers • hardware and software developers • regional standards-making organizations • financial institutions • ITU shaped by the industry it serves

  5. ITUMEMBERSHIP • Member States (governments): 189 • Sector Members: 660 • Recognised Operating Agencies • Scientific or Industrial Organisations • Other entities dealing with telecom matters • Regional or other International Organisations • Region Telecommunication Organisations • Intergovernmental Orgs. operating sat. systems • Associates

  6. ITUGoverning Bodies • Plenipotentiary Conference • Constitution and Convention of ITU • Council • policies and strategy • coordination role • World Conferences • to negotiate agreements serving as basis for operation of global telecoms services • Radiocommunication Conferences, e.g. WRC-2000

  7. World Radiocommunication Conferences (WRC) • Changes to the Radio Regulations • accommodate new systems and services • increased demands for spectrum • Table of frequency allocations (Article 5) • 9 kHz – 275 GHz • footnotes • Frequency plans • e.g. broadcasting satellite plan at ~ 12 GHz • assignment plans • allotment plans

  8. ITUORGANISATION • Radiocommunication Sector (ITU-R) (secretariat BR) • Telecommunication Standardisation Sector (ITU-T) (secretariat TSB) • Telecommunication Development Sector (ITU-D) (secretariat BDT) • General Secretariat

  9. RADIOCOMMUNICATION SECTOR (ITU-R) Aim: “.. to ensure rational, equitable, efficient and economical use of the radio-frequency spectrum and satellite orbits” “.. to carry out studies and adopt Recommendations on radiocommunication matters”

  10. 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

  11. 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 • Radiocommunication Assembly

  12. 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

  13. 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

  14. 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

  15. 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

  16. 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

  17. 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

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

  19. 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

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

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

  22. 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)

  23. Study Group Products • Technical bases for WRC • Conference Preparatory Meeting (CPM) • CPM report to WRC • Draft ITU-R Recommendations • Handbooks

  24. 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

  25. 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

  26. 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

  27. 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
