World's first laser communication link between a plane and satellite ran at 1 Gbps — 10-watt laser which has a 3,417 mile range and 2.5 Gbps max data rate

General Atomics and Kepler Communications have demonstrated plane to satellite optical communications for the first time, transmitting data at up to 1 Gbps while maintaining a steady connection, despite both transmitter and receiver being in constant motion.
