Abstract

The radio spectrum is highly congested and the demand for wireless data is much worse. Requirement of bandwidth for RF communication is rapidly exhausted. In the present day more bandwidth is found but it’s clearly not enough. Using visible light for data transmission entails many advantages and eliminates drawbacks of transmission via electromagnetic waves outside the spectrum. Visible light communication (VLC) is a data communications medium which uses visible light between 400 and 800 THz (wavelength between 780–375 nm). Visible Light Communication (VLC) is a safe technology if the sender intends to transmit confidential data. LI-FI (light fidelity) aims to build a system which carries out communication using visible light that are employed for indoor illuminations. LI-FI (light fidelity) uses the concept of Visible light communication (VLC) or can be consider as Visible Light Communication (VLC) application. In this project, prototype LI-FI (light fidelity) system for PC to PC text message transfer using Visible Light Communication (VLC) is designed. The project is to establish the communication between any two PC’s using a simple circuit consisting of led in the transmitter side and the photodiode in the receiver side and the communication protocol using visible light.
