Li-Fi Technology in Optical Communication Systems: A Review

Abstract

This paper explores Light Fidelity (Li-Fi) technology, which uses light-emitting diodes (LEDs) to send data, providing an alternative to traditional WiFi that uses radio signals. Li-Fi takes advantage of the unused 300 Terahertz optical spectrum, helping to reduce overcrowding in radio frequency spectrums used by other technologies. The paper discusses the implementation of Li-Fi, compares it with WiFi, and describes some challenges and limitations. The goal is to provide clear insights into how Li-Fi performs, the applications, and the potential issues, showing how it could pave the way for wireless communication for various applications such as vehicles, hospitals, and smart lighting systems.
