— 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)
Terrestrial Free-space optical communication (FSO) links have yet to achieve a mass market success due to the ever elusive 99.999% availability requirement. The terrestrial FSO links are heavily affected by atmospheric fog. To design systems which can achieve high availability and reliability in the presence of fog, accurate and better models of fog(More)
Optical wireless links offer gigabit per second data rates and low system complexity. For ground-space and or terrestrial communication scenarios, these links suffer from atmospheric loss mainly due to fog, scintillation and precipitation. We investigate here the impact of fog, rain and snow effects and evaluate their performance on the basis of attenuation(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)
—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)
— 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)
