China’s AO-MDR Laser Link Delivers 1 Gbps from Geostationary Orbit

Chinese researchers have achieved a record-breaking 1 gigabit-per-second (Gbps) data downlink from a satellite in geostationary orbit (36,000 km above Earth) using an optical laser link – with a laser device as weak as a “night light” or candle in power scmp.com scmp.com. In a recent demonstration, a 2-watt laser beam transmitted data to a…

Laser Leapfrog: Inside China’s Record-Breaking 1 Gbps Geo-Laser Link and the Post-Starlink Future of Space Internet

Imagine beaming a high-definition movie across the globe in less than five seconds using a laser as weak as a night-light. This seemingly sci-fi scenario just became reality: from a geostationary orbit 36,000 km above Earth, a Chinese satellite used a mere 2-watt laser to transmit data to the ground at 1 gigabit per second…

China’s “Night‑Light” Laser vs. Starlink: What a 2‑Watt Beam Really Means for the Coming Orbital Arms Race

China’s June 2025 demonstration of a 1‑gigabit‑per‑second laser down‑link from geostationary orbit sparked sensational headlines claiming a weak “candle‑bright” beam had “pulverized Starlink.” In reality, the 2‑watt transmission was a communications breakthrough, not an anti‑satellite strike. Yet the episode sits at the crossroads of two fast‑diverging trends: (1) a legitimate push to replace crowded radio channels with…
