Parametric evaluation of line-of-sight (LOS) channel in LiFi networks

Abstract Light Fidelity (LiFi) based on data transfer with visible light offers a more profound solution to the wireless communication paradigms. This study brings focus on how the line-of-sight (LOS) channel can be used to enhance the performance of a LiFi network. We discuss the LOS channel characteristics, system features, and deployment considerations with respect to evolution and prospects. Experimental modelling and conditions testing involve Q-factor, bit error rate (BER) and data rates analysis. The results presented in this study suggest that both the characteristics of channels and the data transmitted affect the efficiency of the network; higher data rates and longer distances lead to increased BER and lower Q-factor. The outcome of this study reveals key factors which influence the channel performance and provides a guideline that would be beneficial in advancing the LiFi system implementation for different applications. It is hoped that the findings of this study are useful for network engineers and researchers to design better and more flexible LiFi systems for various communication applications.
