François Rancy Chairman, ITU Special Committee Regulatory aspects of the spectrum utilisation by satellite IP and multimedia François Rancy Chairman, ITU Special Committee

What are multimedia and IP services ? Satellite IP services already exist connection to international backbone VSAT networks interactive digital TV Multimedia services encompass a wide range of applications: sound and TV broadcasting data IP multicast web, email, intranet (VPN) Workshop on Satellites in IP and Multimedia - Geneva, 9-11 December 2002 09.09.2019

Typology of services and users Workshop on Satellites in IP and Multimedia - Geneva, 9-11 December 2002 09.09.2019

What kind of applications will be delivered through HDFSS ? Applications using asymmetric traffic forward link : hub -> terminals (content) up: FSS, down: HDFSS (bit rate: 1-36 Mbps) return link : terminal -> hub (requests) up: HDFSS, down: FSS (bit rate: 64-512 kbps) Applications using symmetric traffic VSAT-type meshed networks Two needs : 1. a minimum amount of HDFSS up and down for symmetric traffic 2. more HDFSS downlink for asymmetric traffic Workshop on Satellites in IP and Multimedia - Geneva, 9-11 December 2002 09.09.2019

Satellite IP/MM spectrum requirements National level Definition of appropriate licensing procedures Coordination regional level Spectrum harmonization and protection Workshop on Satellites in IP and Multimedia - Geneva, 9-11 December 2002 09.09.2019

International Legal framework Development of Satellite IP and multimedia require adequate spectrum/orbit resources and access conditions at international level These resources and conditions are specified in the Radio Regulations (RR) The RR is periodically reviewed by World Radio Conferences (WRCs) Workshop on Satellites in IP and Multimedia - Geneva, 9-11 December 2002 09.09.2019

Satellite IP/MM spectrum requirements Need for more spectrum ? Use currently allocated frequency bands which are less congested Use other types of orbits Improve conditions of use of currently allocated bands Make new allocations More freedom to use it ? Use non-shared bands Use planned bands Make regulatory changes Workshop on Satellites in IP and Multimedia - Geneva, 9-11 December 2002 09.09.2019

Satellite IP/MM spectrum requirements Convergence FSS/MSS for transportable terminals ? MSS/MS for dual-mode terminals ? Appropriate protection : what does “harmful interference” mean ? How to protect unlicensed terminals ? Workshop on Satellites in IP and Multimedia - Geneva, 9-11 December 2002 09.09.2019

Allocations to space services available to satellite IP/MM Fixed-satellite service (FSS) C-band (2 x 800 MHz non-planned/2x 300 MHz planned) Ku-band (2 x 750/1000 MHz non-planned/2 x 500 MHz planned) Ka-band (2 x 2.5 GHz non-planned) Mobile-satellite service (MSS) Broadcasting-satellite service (BSS) 2 x 800 MHz/500 MHz planned Ku-band 2 x 400 MHz non-planned at ka-band 25 MHz for BSS (sound) below 3 GHz Workshop on Satellites in IP and Multimedia - Geneva, 9-11 December 2002 09.09.2019

WRC-95/97 decisions Simplifications of the RR 2 x 500 MHz earmarked at Ka-band for non-GSO and GSO sharing based on coordination 2 x 400 MHz for non-GSO MSS feeder links at Ka-band shared with GSO based on coordination 2 x 3.5 GHz for non-GSO/GSO sharing at Ku and Ka-band, based on GSO protection (limits) 500 MHz uplink for LMSS at 14 GHz Workshop on Satellites in IP and Multimedia - Geneva, 9-11 December 2002 09.09.2019

WRC-2000 decisions Finalisation of sharing conditions relating to non-GSO FSS BSS replaning in Regions 1 and 3 Updating of technical parameters Improved sharing conditions Workshop on Satellites in IP and Multimedia - Geneva, 9-11 December 2002 09.09.2019

WRC-03 issues related to multimedia applications Traditional use for IP applications: Finalisation of BSS/FSS sharing criteria at 12 GHz Use of the band 13.75-14 GHz Niche markets based on IP services: New AMSS allocation at 14 GHz ESV at C and Ku band New multimedia applications: HDFSS above 17.3 GHz Workshop on Satellites in IP and Multimedia - Geneva, 9-11 December 2002 09.09.2019

WRC-07 issues Appendix 30B ? Workshop on Satellites in IP and Multimedia - Geneva, 9-11 December 2002 09.09.2019

Conclusions RR will remain technologically neutral Nothing should prevent the use of multimedia applications in any band allocated to a space service. National or regional policies need to take into account operational features easier to use non-shared bands easier to adapt existing systems for new applications Protection/unconstrained operation has a cost Workshop on Satellites in IP and Multimedia - Geneva, 9-11 December 2002 09.09.2019
