Availability of free-space optics (FSO) and hybrid FSO/RF systems [PDF]
SPIE Proceedings, 2001 Free Space Optics (FSO) has become a viable, high-bandwidth wireless alternative to fiber optic cabling. The primary advantages of FSO over fiber are its rapid deployment time and significant cost savings. The disadvantage of FSO over fiber is that laser power attenuation through the atmosphere is variable and difficult to predict, since it is weather ...
