Performance optimization of free-space optical communication protocols based on results from FSO demonstrations [PDF]
The mobile free-space optical channel mainly suffers from relatively long link outages, produced by short-term blockings of the line-of-sight (obstacles, clouds), pointing- and tracking-errors or deep signal-fades caused by index of refraction turbulence
