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

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

• 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

Spot beam capacity can be progressively improved up to 10Mb/s along with mobile content usage

• Spot beam capacity can be progressively improved up to 10Mb/s along with mobile content usage

• Increased number of Terrestrial repeaters
• Additional satellites
• Full 30 MHz allocation
• Use of Beyond 3G waveform

• Also direct satellite return link for Voice and messaging services for telematics and public safety

• Carry out standardisation and regulatory activities

S-DMB is a typical “satellite component” of IMT-2000

• 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
