Weather Effects Impact on the Optical Pulse Propagation in Free Space
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. The authors investigate here the impact of fog, rain and snow effects and evaluate their performance on the basis of attenuation data collected for the optical pulse propagated through the troposphere. Free-Space Optics (FSO) or optical wireless communication is the concept of transmitting very high bandwidth digital data using laser beam directly through the atmosphere.
