Shadowed FSO/mmWave Systems With Interference [PDF]

IEEE Transactions on Communications, 2019
We investigate the performance of mixed free space optical (FSO)/millimeter-wave (mmWave) relay networks with interference at the destination. The FSO/mmWave channels are assumed to follow Malaga-M/Generalized-K fading models with pointing errors in the FSO link.

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 ...
