无信号也能上网！我国低轨卫星通信或二季度开放

Core Viewpoint - China's low Earth orbit (LEO) satellite communication is expected to be opened in the second quarter of 2024, specifically between April and June, allowing smartphones that support this technology to connect directly to satellites for internet access in areas without signal or network coverage [1][10]. Group 1: Low Earth Orbit Satellite Communication - The Huawei Mate X6 Collector's Edition is the first smartphone to support tri-network satellite communication and is currently the only mass-market smartphone with LEO satellite internet capabilities [1][11]. - The LEO satellite internet system is still under testing, with public testing expected to begin in the second half of 2025, although there have been delays due to various issues [3][11]. Group 2: Advantages of Low Earth Orbit Satellites - LEO satellites have unique advantages over medium and high orbit satellites, including lower signal propagation delay, reduced signal attenuation, and better energy efficiency due to their proximity to the Earth's surface [5][13]. - LEO satellites enhance communication efficiency by shortening the distance between smart terminals and satellites, making them crucial for scenarios such as rescue operations and scientific research when ground-based communication infrastructure is unavailable or damaged [5][13]. Group 3: "Thousand Sails Constellation" Project - The "Thousand Sails Constellation" is a low Earth orbit satellite internet system being developed in China, aiming to deploy over 10,000 broadband multimedia satellites by the end of 2030 [7][15]. - This satellite network is designed to provide high bandwidth, low latency, high quality, high security, and global coverage, with approximately 14,000 satellites needed to cover most human living areas effectively [7][15].
