Design and implementation of a Radio on visible light system for indoor communication

Abstract

Visible light communication is a data communication medium, uses the light spectrum between 390nm-700nm. LEDs are used for data transmission along with illumination purpose in visible light communication (VLC). LEDs can easily switch ON and OFF with logical `1' & `0' and data can be sent serially. There are many areas where we can implement VLC but one of the promising stretches that could possibly revolutionize the telecommunication industry is deployment of optical wireless in GSM system. Because of the restriction of Radio Frequency (RF) in some places like hospitals, airplane, petrol stations etc. VLC can be used as an alternative solution for those. The main aim of this project is to design and analyses the optical wireless system to provide connectivity to users in low restricted RF region. A prototype model of the Radio on visible light (RoVL) is proposed to be developed and tested.
