Abstract
Atmospheric free-space optical (FSO) transmission is one of the various types of wireless communication that are being developed today. This is an important alternative to consider for next-generation broadband to support high bandwidth. In this study we demonstrate the feasibility of using an FSO system in a 5G architecture operating in Côte d’Ivoire weather conditions, mainly in the following Korhogo, Man, Bouaké, Bondoukou, Man and Abidjan. Such an architecture requires high quality interconnection between the different parts of the network. To conduct this study, we collected meteorological data from January 2018 to December 2022 for each of these towns on the ’weather history’ site. To characterize our propagation channel, we used the Gamma-gamma model. Attenuation levels caused by meteorological factors such as rain, fog, humidity and temperature were evaluated. Rain proved to be the most attenuating factor for FSO signals in Côte d’Ivoire, with attenuation levels of up to 5 dB/Km. The performance of these systems was analyzed in terms of signal-to-noise ratio and bit error rate. The results show that the rainy season is the least favorable time to deploy an FSO link, and that Man is the least favorable environment for such deployment. The Korhogo environment and the dry season are the most favorable for deploying an FSO connection. Similarly, for setting up an FSO connection, it is preferable to favor connection distances of less than 4.5 km.
