— Free Space Optics (FSO) is now a well established access technology, better known for its robustness in transmitting large data volumes in an energy efficient manner. However the BER performance of a FSO ground-link is adversely affected by cloud coverage, harsh weather conditions, and atmospheric turbulence. Fog, clouds and dry snow play a detrimental(More)
—Wireless optical communication links has the great potential to serve for an increasing demand for high bandwidth transmission capabilities. However, the widespread deployment of wireless optical communication system has been hampered by reliability or availability issues related to atmospheric variations. Among atmospheric effects on wireless optical(More)
Wireless Optical Communication Links (OCL), or Free Space Optics (FSO) links involving optical ground stations (OGS) are highly influenced by the earth atmosphere due to the interaction of the optical wave with particles of different size and shape. Fog, clouds, rain and snow cause significant signal attenuation thus limiting the performance of OCL. In this(More)
— Optical Wireless link provides high bandwidth solution to the last mile access bottleneck. However, an appreciable availability of the link is always a concern. Free Space Optics (FSO) links are highly weather dependent and fog is the major attenuating factor reducing the link availability. However the traffic requirement of a LAN may not require 99.999%(More)
— High bandwidth optical wireless communication links are of prime importance, having tremendous potential to serve for the future huge data transmission requirements especially for the next generation optical networks. The inherent electromagnetic nature of the transmitted optical signals and the stochastic nature of the earth atmosphere create a number of(More)
