Abstract

Currently, wireless internet access is possible thanks to new technologies such as Wireless Fidelity (Wi-Fi). Known as IEEE 802.11, Wi-Fi enables high-speed data transmission with a range of 150 Mbps using WLAN -11n. Faced to many security, transmission capacity and throughput problems, and especially interference, it was necessary to seek more robust wireless access technology to solve these problems. The optical band available is untapped and provides promising solutions by being able to provide tens of gigabit per second specifically suitable for indoor settings. An important revolution through the use of breakthrough technology of Visible Light Communication (VLC) or Li-Fi (light fidelity) could promise much higher data rates and better security and integrity of the data at the physical layer. This new technology called "data by lighting” allows the transmission of data by illumination by sending it via a LED light bulb whose intensity varies very quickly without being perceived by the human eye. This paper, provides an introduction to Li-Fi, the results presented in this paper was realized using MATLAB.
