INCREDIBLE INNOVATION IN VISIBLE LIGHT COMMUNICATION - LIGHT FIDELITY (LI - FI)

Light Fidelity (Li - Fi), high speed communication and networking variant of Visible Light Communication (VLC , aims to utilize a vast amount of unused electromagnetic spectrum in the visible light region. It provides a transmission of data through illumination by sending data through an LED light bulb that varies in in tensity faster than the human eye can follow. Li - Fi provides a better bandwidth, efficiency, availability and security than the existing technology (Wi - Fi). By using visible light as transmission medium, it provides wireless indoor communication of achieve d bit rate of 10Gbps. As there are more and more devices coming up day - by - day the signals are being clogged up due to heavy traffic, there arise a error free transmission and the solution to this p roblem was the Li - Fi technology .
