Abstract

The study was conducted at University of Gujrat during 2015 with an objective to explore the effects of dust on Free Space Optics (FSO) communication. Growing pollution and dust gales motivated studies we presented in this paper. In this paper analysis of the influence of dust on free space optics communication is presented. We focused our studies on Lahore as it is polluted city of Punjab and made a comparison with dust effects in Rahimyar Khan Region. Dense dust consists of large dust particles that raise from Earths sphere and whose atmospheric intensification values are high enough to affect FSO communication links. Dust storm research is based on visibility data. In order to test visibility data, we made calculations of atmospheric conditions for different dust conditions. Visibility of wave is calculated using weather spark. As it is related with the optical attenuation, so we also calculated optical attenuation of dust particles due to influence of dust particles and compared it with that of Rahimyar Khan.
