Research Paper: High data rate ground-to-train free-space optical communication system

Researchers from Keio University (Japan) and Railway Technical Research Institute (Japan) developed a new technology that does the acquisition, stable tracking, and fast handover for free space optical links to high-speed trains.

Their prototype provided a stable communication link between a train and the ground at a data rate near 1  Gb/s with a handover time on the order of 100 ms.
