China’s 1Gbps Satellite Internet Breakthrough Set to Outpace Starlink
Chinese researchers have made a major leap in satellite internet technology, achieving 1Gbps transmission speeds—five times faster than current Starlink capabilities. This innovation could redefine global connectivity and challenge the dominance of existing providers.
Pioneering New Technology
The research, led by Liu Chao of the Chinese Academy of Sciences and Professor Wu Jian of Peking University, combines Adaptive Optics (AO) and Mode Diversity Reception (MDR). These technologies counteract atmospheric interference, delivering fast, stable internet from space.
High Speed from High Orbit
Unlike Starlink’s low Earth orbit satellites, which operate around 341 miles above Earth, the Chinese system functions at a much higher altitude—22,807 miles. Despite the greater distance, the team managed to maintain a reliable 1Gbps connection with low signal error rates.

The achievement was made using a 5.9-foot telescope at the Lijiang Observatory and a two-watt laser, similar in power to a nightlight. This setup allowed precise signal control and real-time adjustments, ensuring connection quality despite the satellite’s distance.
Broader Implications
The success of this test goes beyond internet speed. It has implications for space communication systems, satellite navigation, and missions requiring high-speed data transfer. It could also bring reliable internet to rural or remote areas, offering an alternative where traditional broadband is unavailable.
With nearly 20% improvement in signal accuracy over past systems, this development is a proof of concept that raises the bar for satellite communication technologies.
A Challenge to Global Providers
If commercialised, China’s new system could offer a serious alternative to Starlink and similar services. Its superior speed, reach, and stability position it as a next-generation solution for both everyday users and critical infrastructure.
Though still experimental, the technology has been published in Acta Optica Sinica and is gaining attention in the global tech community. Experts say its potential could spark a competitive shift in the satellite internet industry.
