Core Insights - The core viewpoint of the articles emphasizes that 6G will achieve deep integration of communication satellites with terrestrial networks and low-altitude platforms, creating a seamless global network that provides high-speed connectivity to every corner of the Earth [1][11]. Group 1: Technological Advancements - 6G is expected to redefine information transmission, processing, and cognition, becoming a critical infrastructure for the intelligent era, akin to the "nervous system" of future digital societies [1]. - The introduction of ultra-broadband optoelectronic integrated systems has enabled flexible and tunable high-speed wireless communication, laying the groundwork for more reliable 6G wireless communication [2]. - 6G will utilize the terahertz (THz) frequency band (0.1–10 THz), potentially increasing peak transmission rates to terabits per second (Tbps), which is tens to hundreds of times faster than 5G [2]. Group 2: Applications and Use Cases - The 6G network's capabilities are being demonstrated through applications such as drone delivery, which can significantly enhance delivery efficiency and reduce time by 2 to 3 times compared to human delivery [3]. - 6G is anticipated to support various sectors, including smart manufacturing, logistics, emergency rescue, and healthcare, by enabling real-time monitoring and predictive maintenance through integrated communication and sensing [12][13]. Group 3: Global Competition and Development - Major countries and regions are actively pursuing 6G research and development, with the U.S., EU, Japan, and South Korea investing heavily to maintain their competitive edge [4]. - China is leveraging its strong foundation in 5G, vast market applications, and collaborative innovation to transition from a "follower" to a "leader" in the global 6G landscape [1][4]. Group 4: Infrastructure and Ecosystem - As of July 2023, China has established 4.598 million 5G base stations, providing a robust network foundation for the development of 6G [5]. - The extensive mobile communication user market and diverse application ecosystem in China offer significant opportunities for 6G innovation and business model exploration [5][6]. Group 5: Key Technologies and Innovations - China has made substantial progress in key 6G technologies, with over 300 critical technology reserves and a leading position in global 6G patent applications, accounting for approximately 40.3% [7]. - The establishment of the IMT-2030 (6G) Promotion Group has facilitated collaboration among operators, manufacturers, universities, and research institutions to drive systematic research and innovation in 6G technologies [7][8]. Group 6: Future Outlook - The commercialization of 6G is expected to begin around 2030, with a projected market size of trillions of yuan by 2035, indicating a significant economic impact [11]. - The integration of AI with 6G is anticipated to enhance communication performance and provide a foundational platform for AI applications across various industries [3][12].
