China has officially begun its transition to 6G technology following the launch of a test satellite on February 3, 2024. This milestone marks the first step toward the commercialisation of 6G networks, targeted for completion by 2030.
Development and Objectives
The low-earth orbit satellite, developed by China Mobile and the Chinese Academy of Sciences, is designed to explore integrated space and ground communication networks. This innovative satellite supports a distributed system that allows adaptable deployment of core network functions and software updates in orbit, aligning with China’s ambitious 6G sector plans.
Advancements Over 5G
The anticipated 6G network promises significant advancements over 5G, including higher speeds, lower latency, and new applications in pervasive intelligence, the Internet of Things (IoT), and ultra-low latency communications. These improvements could benefit various sectors such as digital twins, smart agriculture, and precision healthcare.
Enhanced Capabilities
The satellite’s low-earth orbit enables reduced latency and enhanced data transfer rates compared to traditional high-orbit satellites. This capability potentially boosts global satellite internet services and helps bridge gaps in terrestrial mobile networks.
Experimental 6G Field Test Network
In July, Chinese engineers from the Beijing University of Post and Telecommunications demonstrated a 6G field test network using existing 4G infrastructure. This experimental network, employing semantic communication, reportedly achieved a tenfold increase in key metrics like capacity and coverage. Professor Zhang Ping, who leads the research team, highlighted the importance of integrating communication technology with AI, suggesting that 6G’s widespread reach will largely enhance AI abilities. This network exemplifies the deep integration of communication technologies and AI, which experts predict will enable new digital economy business models.
Global 6G Developments
Globally, other countries are also advancing in 6G development. Japan aims to establish key 6G technologies by 2025 and plans to offer “beyond 5G” services by 2030 through partnerships with major companies like NTT Docomo and Sony. Similarly, the United States and nine other countries have outlined principles for 6G networks, focusing on national security, spectrum efficiency, and privacy protection.
Conclusion
China’s launch of the test satellite marks a significant step in the global race towards 6G technology. With ambitious plans and cutting-edge innovations, China is positioning itself as a leader in next-generation communication networks, setting the stage for a new era of digital connectivity and technological advancements.
