Objectives of ITU-R
•Global coordination of radiocommunications
•ITU Radio Regulations
•International Spectrum Management
•Frequency Plans
Objectives of ITU-R
•Global coordination of radiocommunications
•International focal point for standardization of wireless systems
Recommendations - de facto Standards on:
•spectrum management issues
•radiocommunication system characteristics and operation
Example topics:
•radiowave propagation
•wireless access systems
•EESS systems
•broadcasting
Objectives of ITU-R
To promote the development and use of
radiocommunications for the benefit of all
•Global coordination of radiocommunications
•International focal point for standardization of wireless systems
•Promote the world-wide development of radiocommunications
ITU-R Objective
Objective achieved through (inter alia):
• World and Regional Radiocommunication Conferences
• Approval of Recommendations by Member States by correspondence at Radiocommunication Assembly
Technical studies are requiredwhich are conducted in Study Groups
ITU-R Study Groups
• Groups of experts (> 1500)from ITU membership
• Develop technical bases for WRCs and RRCs
• Develop Recommendations technical characteristics operational procedures
• Compile Handbooks
ITU-R Study Groups
SG 1: Spectrum managementSG 3: Radiowave propagationSG 4: Fixed-satellite serviceSG 6: Broadcasting serviceSG 7: Science servicesSG 8: Mobile servicesSG 9: Fixed service
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
Radiocommunication Assembly
• Establishes ITU-R Study Groups (and elects their chairmen/vice-chairmen)
• Adopts SG work programmes• Approves Recommendations• Approves Resolutions
working procedures specific aspects of SG responsibility
Scope of Study Group 7(Science services)
• Systems for space operation, space research, Earth exploration and meteorology
• Radio astronomy• Standard frequency and time signals
SG 7- some key areas of study -
• Allocations for space science services space operations and space research
services Earth exploration satellite service meteorological services
• Compatibility between science services (active and passive) and other services (including sharing and protection criteria)

WRC-07 Agenda items
1.2, 1.20, 1.21
1.2: Allocations and related regulatory issues for EESS (passive), SRS (passive) and Meteo-Sat in 18.1 – 18.4 GHz, 10.6 – 10.68 GHz and 36 – 37 GHz
1.20: Protection of EESS (passive) (bands 1400 – 1427 MHz, 23.6 – 24 GHz, 31.3 – 31.5 GHz, 50.2 – 50.4 GHz) from unwanted emissions of active services
1.21: Compatibility between RA and active space services (bands referred to in Res740) in order to review and update the threshold levels used for consultation (Annex to Res739)
AI 1.2: Allocations and related regulatory issues for EESS (passive), SRS (passive) and MetSat in 18.1–18.4 GHz,
10.6–10.68 GHz and 36–37 GHz (1)Current results of studies (18.1-18.4 GHz):
• the addition of 100 MHz seems feasible under certain conditions (but compatibility between MetSat and NGSO FSS not studied);
• proposes additional allocation, either 18.0-18.1 or 18.3-18.4 GHz;
• indication that 18.0-18.1 GHz option may impose minor constrains on MetSat orbital positions due to operation of BSS feeder-links of networks belonging to Regions 1 and 3 BSS Plans/Lists (Appendix 30A)
AI 1.2: Allocations and related regulatory issues for EESS (passive), SRS (passive) and MetSat in 18.1–18.4 GHz,
10.6–10.68 GHz and 36–37 GHz (2)
Current results of studies (10.6-10.68 GHz and 36-37 GHz):
• interference from FS in 10.6-10.68 GHz band may exceed limits for EESS sensors by ~17 dB; mitigation therefore necessary;
• preliminary sharing criteria proposed for 36-37 GHz band, but not to be applied to terrestrial systems brought into use before WRC-07
AI 1.20: Protection of EESS (passive) (bands 1400 – 1427 MHz, 23.6 – 24, 31.3 – 31.5, 50.2 – 50.4 GHz) from unwanted
emissions of active services
Current results of studies:
• TG 1/9 revising Rec. ITU-R SM.1633, which should be used as a basis for developing EESS protection criteria;
• proposed to include unwanted emission power [limit /level] in RR; sensors protected but some limitation on future active systems;
• still at a preliminary stage.
AI 1.21: Compatibility between RA and active space services (Res.740) in order to review and update threshold
levels used for consultation (Annex to Res.739)
Current results of studies:• proposed PFD threshold levels for RAS
protection from interference from different services;
• 3 methods are under consideration: 1st –add approved thresholds in Res.739 and
apply them (RAS protected, but more work for ADMs due consultation);
2nd similar to 1st but RNSS is not covered (no burden for ADMs but RAS may not be protected in 1559-1610 MHz);
3rd no incorporation of thresholds (TBD).
