On robust FSO network dimensioning
2017 9th International Workshop on Resilient Networks Design and Modeling (RNDM), 2017 The presented work is motivated by Free Space Optics (FSO) communications. FSO is a well established wireless optical transmission technology considered as an alternative to radio communications for example in metropolitan wireless mesh networks. An FSO link is established by means of a laser beam between the transmitter and the receiver placed in the ...

Cascaded FSO-VLC Communication System [PDF]
IEEE Wireless Communications Letters, 2017 The proposed cascaded free space optics (FSO)-visible light communication (VLC) system consists of multiple VLC access points which caters the end users connected via a decode and forward relay to the FSO backhaul link. The FSO link is assumed to be affected by path-loss, pointing error, and atmospheric turbulence while the end-to-end signal-to-noise ...

Evaluation of FSO link throughput in Qatar
2015 4th Mediterranean Conference on Embedded Computing (MECO), 2015 Despite the vibrant advantages of Free Space Optics (FSO) technology and the variety of its applications, its widespread adoption has been hampered by rather disappointing link reliability for long-range links due to atmospheric turbulence-induced fading and sensitivity to detrimental climate conditions.

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.

WiMAX on FSO: Outage Probability Analysis [PDF]
IEEE Transactions on Communications, 2012 The transmission of multiple wireless signals over optical links has attained a great research interest nowadays. In case where optical fibers are difficult to be deployed, or installation cost is prohibited, optical wireless systems provide an efficient alternative means.
