Hybrid satellite/terrestrial architecture: Global coverage for Outdoor & Indoor usage

Low cost impact on 3G handheld terminal• Satellite frequencies are adjacent to IMT2000 terrestrial ones• Satellite waveform compliant to 3GPP UTRA FDD WCDMA standard• High reception margin, hence no form factor impact

Concurrent evolution with 3GPP architecture

Return link: PPDR, safety

Agenda




WRC-07 preparatory activities S-DMB is a typical “satellite component” of IMT-2000 WRC-07 Agenda Item 1.4: Requirements for evolutions of IMT-

2000, and systems beyond IMT-2000.• Emerging concepts (S-DMB, others): Satellite has an important

role to play in the future of IMT-2000• Satellite may not be suited for all mobile applications, but it is

excellent for some (multicast, coverage complement, reliable communications)

Technological evolutions• Trend towards integration between terrestrial/satellite mobile

systems: system, waveforms• Higher satellite power, bigger antenna technology enables

seemless terrestrial/satellite access on the same terminal !• The role of satellite should be fully recognised in WRC-07 A.I 1.4

preparation WP8F and WP8D cooperation should continue to enable

satellite to fully play its role in future mobile systems

Thank you for your attention !
