Abstract

Li-Fi technology is a type of visible light communication that uses LEDs as a data transmission source. Li-Fi is expected to occupy an important place in wireless network technology by providing high-speed internet access and having high bandwidth. It may be a common technology to provide internet access instead of Wi-Fi in places where radio waves are inconvenient, such as hospitals and airplanes. In this paper, a comprehensive Li-Fi system model implemented using Simulink® is proposed and evaluated. The model is equipped with a mirror and a thin convex lens to increase the efficiency of the Li-Fi system by reflecting and focusing the light beam emitted from the LEDs. The result obtained from the evaluation test shows that the output signal from the model of the proposed Li-Fi system is much higher than that of the basic Li-Fi system. Thus, using the proposed comprehensive model, more efficient Li-Fi systems can be realized.
