On the performance of FSO communications links under sandstorm conditions

In this paper we focus in the analysis of the FSO link performance under sandstorms conditions. The sandstorms are characterized by the size of the particles and the necessary wind speed in order to blowing them up during a minimum period of time. Sandstorm is a well know problem in many parts of the world and different reports has been presented regarding the impairments that sandstorms produces on outdoor link communications. The paper first focuses on the indoor laboratory sandstorms chamber and that is being used to investigate the performance on an FSO link. We propose an improvement to chamber with a dedicated customised structure where wind speed, sand blowing and turbulence can be generated, controlled and maintained over a much longer time period. This study would help in the deployment of a stable state of the art sandstorm environment for assessing FSO communication links.
