    Abstract
    Free space optical (FSO) communication systems are affected by dust particles suspended in the atmosphere in arid and semi-arid regions. The presence of these particles in the air severely affects the optical link, reduces its availability and causes service outage. In the literature, the effect of dust on the microwave signals has been widely investigated. However, for FSO communication systems that exploit shorter wavelengths, information and research is still very limited yet almost inexistent. Therefore, in this paper, we investigate the performance of FSO links under dust storms. We designed a chamber to emulate this specific environment and carry out measurements. From the experimental investigations, we derive and propose an empirical model for the signal attenuation as a function of the visibility range. The results show acceptable performance for FSO links, under moderate and light dust, with potential reach distance of hundreds of meters to few kilometers. Furthermore, a comparison analysis shows that the dust induces 7 times higher attenuation than fog.

    The export option will allow you to export the current search results of the entered query to a file. Different formats are available for download. To export the items, click on the button corresponding with the preferred download format.

    By default, clicking on the export buttons will result in a download of the allowed maximum amount of items. For anonymous users the allowed maximum amount is 50 search results.

    To select a subset of the search results, click "Selective Export" button and make a selection of the items you want to export. The amount of items that can be exported at once is similarly restricted as the full export.

    After making a selection, click one of the export format buttons. The amount of items that will be exported is indicated in the bubble next to export format.
