link handling due to atmospheric turbulence in free space optical communication for optical wireless terrestrial networks

Abstract

newline Free-space optical (FSO) communication is an emerging technology that uses light waves to transmit data, providing a faster and more efficient alternative to traditional wired communication. An introduction to the fundamentals, elements, and uses of FSO technology is given at the outset of this work. The benefits of FSO are examined, including fast data speeds, minimal latency, and secure transmission. However, the inherent drawbacks are also discussed, including vulnerability to air turbulence. The communication performance is evaluated using the frequency, speed, and wavelength of the waves. A critical analysis of the impact of atmospheric turbulence on FSO links forms a significant aspect of this thesis. However, FSO communication is susceptible to atmospheric turbulence caused by factors such as rain, snow, and fog. Through optical signal fluctuations that can result in signal attenuation, distortion, or in extreme cases, total signal loss, these disturbances have the potential to severely impair the operation of FSO systems. newline
