Comparison of different models for prediction of attenuation from visibility data

Abstract

The benefits of Free space Optics (FSO) motivates to use it for future high data rate demanding communication applications. However, widespread growth of the technology has been hampered by reduced availability due to weather influences on the link. The fog has been analysed as the most detrimental for FSO communication. There are some models that predict fog attenuation in terms of visibility. These models are compared with measured attenuation data. The comparison has been in terms of Mean Square Error (MSE).
