Impact of physical and geometrical parameters on visible light communication links

Abstract

This paper studies the impact of various parameters used for modeling indoor VLC channels, considering a mobile user within the confined environment. The main investigated parameters are either physical or geometrical. First, we classically study the impact of optical properties of surface materials. Then, the effect due to the presence of the user body inducing various VLC receiver orientations is analyzed. Finally, different body and furniture sizes and levels of details are also investigated. This study explores whether it is necessary and how to model the channel regarding the studied parameters. The results are established according to VLC link quality and data rate.
