— 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)
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)
The increased interest in long lasting wireless sensor networks motivates to use Free Space Optics (FSO) link along with radio frequency (RF) link for communication. Earlier results show that RF/FSO wireless sensor networks have life time twice as long as RF only wireless sensor networks. However, for terrestrial applications, the effect of weather(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)
In this paper, the performance of Radio on Free Space Optics (RoFSO) a cost effective and efficient method of wireless transmission that supports high data rate of communication as compared to optical fiber, whose data rate is limited by dispersion and nonlinearity is studied. The performance primarily depends on atmospheric conditions which is the recent(More)
