A Chinese firm has achieved a 100 Gbps high-speed data transmission in tests last week using satellite-to-ground laser communications. Chang Guang Satellite Technology Co., the country’s first remote-sensing satellite maker and operator of the Jilin-1 constellation of satellites, transmitted data between a truck-mounted ground station and one of the 117 satellites in the Jilin-1 constellation.
This achievement is 10 times faster than the previous record and places Chang Guang Satellite ahead of Starlink, the space company owned by billionaire Elon Musk. The company aims to equip all satellites in the Jilin-1 constellation with laser communication units to enhance efficiency, targeting a network of 300 satellites by 2027. The next generation of wireless technology, 6G is designed to be much faster than 5G, with speeds over a terabit per second and extremely low latency of just 100 microseconds. It aims to provide global coverage by combining networks on land, in the air, and in space, using higher frequency waves, such as those in the terahertz range
