Simulation and Implementation of Li-Fi Communication System
Abstract
The design, implementation, and performance evaluation of an arduino-based Light Fidelity (Li-Fi) communication system is presented in this study. Li-Fi is a Visible Light Communication (VLC) system that transfers data wirelessly at high speeds and with minimal energy consumption using Light-Emitting Diodes (LEDs). Utilizing current LED lighting systems for illumination and data connection, the solution is also energy-efficient. Because of these features, Li-Fi is positioned as a possible solution for use in smart homes, healthcare, aviation, and IoT ecosystems. With On-Off Keying (OOK) as the modulation technique, this work investigates the design of an Arduino-based Li-Fi communication system that uses photodiodes for reception and LEDs for data transmission. The study examines the use of On-Off Keying (OOK) modulation for data transmission and assesses the system's performance regarding Bit Error Rate (BER), data rate, and environmental adaptability. Future IoT applications will be made possible by the results, which show that Arduino-based Li-Fi devices are feasible for safe, short-range indoor connectivity with low latency and high data rate transmission.
