China has achieved a major milestone in satellite internet technology, delivering speeds of up to 1 Gbps—five times faster than Elon Musk’s Starlink. This leap was accomplished using a 2-watt laser transmission from a satellite orbiting over 36,000 km above Earth, far higher than Starlink’s low-orbit fleet.
To overcome atmospheric turbulence, which typically distorts laser signals, Chinese scientists led by Prof. Wu Jian and Dr. Liu Chao introduced a novel AO-MDR (Adaptive Optics Mode Division Receiver) synergy.
This breakthrough reshapes distorted laser beams using 357 micro-mirrors and enhances signal precision via a multi-plane light converter and real-time path-picking algorithm.

Chinese scientists have just pulled off a major tech leap: beaming data from space to Earth using a 2 W laser, faster than a candle’s brightness, yet blazing at 1 Gbps — that's five times quicker than Starlink’s satellite internet! They combined cutting-edge methods (Adaptive Optics + Mode Diversity Reception) to beat atmospheric interference and ensure a clean, lightning-fast stream .
This isn't just a cool experiment—it could redefine how we connect globally. Imagine streaming ultra-HD movies, next-gen remote sensing, and even early 6G networks powered by lasers. With mobile ground stations and scalable tech, this could transform internet access everywhere. The future? It’s bright, green, and laser-powered.
