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 1. Radionavigation, radnav-sat and radiolocation services 2. Mobile, mob-satellite and space science services 3. Fixed-satellite and broadcast-sat services 4. Fixed and fixed-sat services and HAPS 5. Maritime-mobile, amateur and am-sat, and b’cast services at MF and HF 6. Other matters 7. 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
