Core Viewpoint - The development of satellite internet is crucial for addressing the limitations of existing terrestrial internet, providing global coverage, enhancing communication speeds, and offering resilience in emergencies [5][10][13]. Group 1: Background and Necessity - The current terrestrial internet has significant shortcomings, including limited coverage, insufficient support for low-altitude economic activities, and vulnerability during emergencies [9][10]. - Approximately 3 billion people globally lack internet access, particularly in remote areas where profitability for operators is low [9]. - The need for satellite internet arises from its ability to provide coverage in challenging terrains such as deserts and oceans, and to support low-altitude devices like drones [10][13]. Group 2: Development Status and Comparison - The satellite internet sector has seen a surge in satellite constellation planning, with over 1,000 satellites planned globally, including significant projects like Starlink and China's own satellite initiatives [14][19]. - China's satellite internet technology is catching up but still lags behind in originality and cost efficiency compared to international counterparts like SpaceX's Starlink, which has achieved significant cost reductions through industrialized production [19][21]. Group 3: Challenges and Future Directions - Key challenges for China's satellite internet development include satellite design, energy supply efficiency, satellite networking technology, and ground station deployment [21][22]. - Future directions involve enhancing rocket technology for higher payload capacity, achieving cost-effective satellite production, and expanding application scenarios to support over 20,000 satellites by 2035 [25][26].
4G、5G这么普及,为什么还要发展卫星互联网?
