Abstract: Li-Fi (Light Fidelity) is a high speed, wireless communication using light. It can be considered under optical wireless communication category. Data is transmitted through Light Emitting Diode bulbs whose intensity varies. Depending on this variation, communication occurs digitally. This technology has broad applications where the use of Wi-Fi (Wireless Fidelity) is restricted or banned. This paper aims to show the transmission of text data from one PC to another PC using Li-Fi which has more advantages than Wi-Fi. For e.g., Li-Fi also eliminates adverse health effects of using electromagnetic waves. Unless illumination is seen, data can't be hacked, therefore data transmission is secure.

Keywords: Light Fidelity, optical wireless communication, Light emitting Diode, Text data Transmission, wireless fidelity.
