Light Fidelity system performance in data transmission through the effect of Free-Space Optical Communication

Li-Fi (light-fidelity) considers a new technology in the wireless communication domain that operates light for transmission free space; the end-user has employed Visible Light Communication based on Light Emitting Diodes. This study aims to investigate the performance of Li-Fi to transmit data like video and pictures using different data rates under atmospheric turbulence such as rain and dust that affect FSO, therefore it affects at end-user and verifies the reliability of the Visible Light Communication (VLC) system sending data at high-speed data transmission. The systems are simulated by Optisystem V 18; the proposed system is built as a VLC system linked with fiber optic and free space optic channels to transmit various video sizes and an image using data rates of about 100 Mbps and 600 Mbps, and 1 Gbps over a lengthy distance under different weather, System was estimated in phrases of bit error rate, quality factor, power of signal, signal to noise ratio, and variation in angles. Despite the harsh environmental conditions imposed on the communication network, VLC has proven its ability to transmit high-speed data transmission for user's requirement.
