Light Fidelity (li-Fi): Wireless Communication and Security

is paper investigates Light Fidelity (Li-Fi), an innovative wireless communication technology that uses visible light instead of traditional radio frequency (RF) waves. It explores the principles behind Li-Fi, how it functions as a communication medium, and its practical implementation in various scenarios. Special focus is given to the security protocols employed within Li-Fi networks, highlighting their role in safeguarding data transmission. The vulnerabilities associated with Li-Fi, such as susceptibility to eavesdropping, signal interference, and unauthorized access, are examined in detail. The paper also proposes security measures to address these challenges, aiming to enhance the reliability and resilience of Li-Fi systems. To assess the real-world impact of Li-Fi, the study incorporates a case study alongside an analysis of prior research. This approach highlights Li-Fi's advantages, including high-speed data transfer, interference-free operation, and enhanced security in specific applications. Limitations and potential solutions are discussed, offering a balanced perspective on its adoption. By analyzing the technical and practical aspects of Li-Fi, this paper provides a comprehensive overview of its potential to transform wireless communication, addressing key challenges while emphasizing its advantages over conventional RF-based systems.
