Design of a LiFi System for Short-Distance Communications

LiFi technology introduces Visible Light communication that uses light as a source to deliver high data speed, which is much greater than that of Wi-Fi. The research paper proposes a communication system that utilizes Light-Fidelity (Li-Fi) technology for short-range wireless communication. The article begins with an introduction to Li-Fi technology and its advantages over traditional wireless communication systems. The paper also highlights the limitations of Li-Fi, including its short range. The authors then present their proposed approach, which includes a transmitter section, a receiver section, and two modes of operation (text and audio). Additionally, the system consists of two applications to demonstrate its functionality: an SOS application and a device on/off application. The paper concludes with a detailed explanation of how the proposed system works and its potential applications in various fields.
