11. WRC-03: Figures and facts • 48 agenda items • 2334 registered participants (without the Secretariat) from 145 Member States • Over 2500 individual proposals • 8 committees, over 60 working groups

12. Agenda Item 1.3:Harmonized bands for public protection • to consider identification of globally/regionally harmonized bands, to the extent practicable, for the implementation of future advanced solutions to meet the needs of public protection agencies, including those dealing with emergency situations and disaster relief, and to make regulatory provisions, as necessary, taking into account RES 645 (WRC‑2000);

13. Agenda Item 1.3:Harmonized bands for public protection • RES 645 (WRC‑2000): Global harmonization of spectrum for public protection and disaster relief • Benefits of globally harmonized bands (increased potential for cooperation between countries, easy deployment, decreased costs) • ITU-R to study identification of appropriate frequency bands to implement future solutions for public protection agencies and organizations • ITU-R to study regulatory provisions necessary to identify such bands • ITU-R to study issues concerning technical and operational matters for cross-border circulation of equipment

14. Agenda Item 1.3:Harmonized bands for public protection • Resolution 646 (WRC‑03): Public protection and disaster relief • Difficulties to identify a single band; several regional bands: • Region 1: 380 – 470 MHz; Region 2: 746 – 806 MHz, 806 – 869 MHz, 4940 – 4990 MHz; Region 3: 406.1 – 430 MHz, 440 – 470 MHz, 806 – 824/850 – 869 MHz, 4940 – 4990 MHz, 5850 – 5925 MHz • Administrations are urged to use regionally harmonized bands for PPDR, taking into account national and regional requirements; special attention to emerging technologies • Complementary support: use of amateur networks • ITU-R to study issues concerning technical and operational matters

15. Intergovernmental Conference onEmergency TelecommunicationsHelsinki, 1998 (ICET-98) • Adopted Convention on the Provision of Telecommunication Resources for Disaster Mitigation and Relief Operations • Provides framework for rapid deployment and effective use of telecommunications in disasters • An intergovernmental pact with provisions for non-governmental organisations

16. Need for a national plan • Countries need a national plan for disaster mitigation and relief operations • Emergency telecommunications and restoration of facilities should be featured • All radio services, including the Amateur Services, should be included in the plan

17. ITU-D Handbook on Disaster Communications Joint effort by UN/OCHA, IARU and ITU-D Includes policy, operations, technical sections

18. Agenda item 1.15: RNSS issues • Review the results of studies concerning the radionavigation-satellite service in accordance with Resolutions 604 (WRC-2000), 605 (WRC-2000) and 606 (WRC-2000)

20. Agenda item 1.38: EESS(active) in 420–470 MHz • to consider provision of up to 6 MHz of frequency spectrum to the Earth exploration-satellite service (active) in the frequency band 420-470 MHz, in accordance with Resolution 727 (Rev.WRC-2000) • Issue: need for assessment and systematic observations of forest cover and rate of forest degradation in tropical and temperate regions • Decisions of WRC-03: • Addition of EESS (active), on a secondary basis, in 432 – 438 MHz band • SUP Resolution 727

21. Agenda item 1.38: EESS (active) in 420 – 470 MHz What is a SAR ? (1) • Most Radars send out a short pulse and determine range of a target by the time taken for an echo to return • Angle to the target is determined by the pointing direction of the high gain receiving antenna • A SAR - Synthetic Aperture Radar - uses the motion of a satellite to “synthesize”an antenna • It uses a crystal controlled signal which is coherent from pulse to pulse • Using signal processing it combines several echos to produce the effect of a very long antenna along the direction of travel

22. Agenda item 1.38: EESS (active) in 420 – 470 MHz What is a SAR ? (2) • Most SARs also sweep the signal over a wide frequency range during a relatively long pulse • On reception, again using signal processing the pulse is compressed to become very short, allowing very accurate range determination • A SAR can therefore produce IMAGES • At a wavelength of 70cm (430 MHz), a SAR can penetrate the earth’s surface to detect moisture around tree roots • It can therefore be used to study the health of tropical forests

23. Agenda for WRC-07 Issues related to space science services • AI 1.2: allocations and related regulatory issues for EESS (passive), SRS (passive) and Meteo-SAT in 18.1 – 18.4 GHz, in 10.6 – 10.68 GHz and 36 – 37 GHz • AI 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
