China launched satellite for testing 6G
China has successfully launched the world’s first 6G test satellite, which was developed by China Mobile and the Chinese Academy of Sciences’ Innovation Academy.
China has successfully launched a satellite for testing 6G network technology, marking a significant milestone in the exploration of integrated space and terrestrial communication technology. The world’s largest telecommunications company for mobile phones, China Mobile, achieved this feat on 3 February, launching the first satellite dedicated to 6G network testing alongside another satellite for 5G networks.
The low-earth-orbit test satellite hosts a distributed autonomous architecture for 6G, utilising Chinese software and hardware to support in-orbit software reconstruction, flexible deployment of core network functions, and automated management, thus enhancing the efficiency and reliability of the in-orbit operation of the satellite core network.
The satellite for testing 6G network technology is a collaborative effort between China Mobile and the Innovation Academy for Microsatellites of the Chinese Academy of Sciences. The system incorporates domestic hardware and software, along with an autonomous, automated management system.
Orbiting at an altitude of nearly 500 kilometres, the satellite offers advantages such as low latency and high data transmission speed compared to satellites positioned at 36,000 kilometers. Low Earth Orbit satellites address the coverage gaps in terrestrial mobile networks, providing satellite internet services worldwide. China Mobile has announced plans to conduct experiments, accelerating the integration and development of space-terrestrial technology industries.
What are the differences between 5G and 6G technology?
- Spectrum usage: 6G will use higher frequencies than 5G, allowing for much faster data transmission and greater bandwidth capacity.
- Data rates and latency: 6G is expected to achieve data rates multiple times faster than 5G and will have lower latency, enabling faster and more reliable data speeds and real-time responsiveness.
- Device connectivity: 6G is projected to support a much greater number of devices, up to 100 million per square kilometer, compared to 5G.
- Security: 6G networks will most probably utilise AI and machine learning to improve security and performance, making them more resistant to cyberattacks and ensuring they can handle the requirements of future applications.
- Coverage: 6G networks are expected to have vast coverage areas and improved cellular network penetration, requiring fewer towers and supporting additional mobile connections beyond 5G
