Abstract

Li-Fi (Light Fidelity) is the transmission of data by visible light (VLC), an alternative to Wi-Fi (Wireless Fidelity), the idea is to set up a system with the aim of e-health in hospitals, with the health crisis of COVID, it has been obligatory at present to take in hand the patients, it is known that the electromagnetic transmission that can generate Wi-Fi can be harmful for the patients, and can even generate interference that can distort the medical report of patients, the Li-fi uses light waves for data transmission, hence the absence of interference and noise [1], which is an advantage of using Li-Fi in indoor environments. In this article, we will make an introduction to the Li-Fi system, we will present a comparison between Li-Fi and Wi-Fi, we will also talk about our system that allows to send a confidential message through the light signal of Li-Fi in full safety without that this last one is decrypted by a malicious person in the part of future works and contribution, and finally a general conclusion of this article.
