China Mobile, the world’s largest telecom carrier by mobile subscribers, has successfully launched the world’s first satellite to test 6G architecture,1.   (mark) a milestone in its efforts to explore integrated space and ground communication technology.

The low-earth orbit test satellite is the world’s first to employ 6G design architecture, and it2.   (launch) on Saturday along with another satellite that comes with China Mobile’s 5G technology.

The 6G test satellite 3.   (host) a distributed autonomous architecture for 6G, which was jointly developed by China Mobile and the Chinese Academy of Sciences’ Innovation Academy for Microsatellites. The system, using domestic software and hardware, supports in-orbit software reconstruction, flexible deployment of core network functions4.   automated management, enhancing the efficiency and5.   (reliable) of the in-orbit operation of the satellite core network, China Mobile said.

Set at an orbit height of approximately 500 kilometers, these experimental satellites offer advantages such as low latency and high data transfer rates 6. (compare) with high-orbit satellites 7.   travel at 36,000 kilometers.

Positioned as 8. crucial platform for future integrated space and ground networks, low-earth orbit satellites can address telecom signal coverage gaps in terrestrial mobile networks, providing higher bandwidth satellite internet services9. (systematic), according to China Mobile.

China Mobile said 10. plans to conduct in-orbit experiments based on these test satellites, accelerating the integration and development of space-to-ground technology industries.

y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
