Visible Light Communication

Abstract

This paper attempts to explain the use of Visible light used to carry out communication and list its advantages over classic radio wave communication. Visible Light Communication (VLC) is basically the transmission of data through illumination where the intensity of light is varied in accordance with the data. VLC offers security, high bandwidth, high data rates and negligible interference acting as a complement to radio frequency communication. The proposed system aims to carry out a successful communication between two or more devices using light as a medium. The input data can be any random data which is converted to binary format, encoded and then transmitted. This signal is then picked by a suitable photodiode and decoded so that the user at the receiver end can read the data. This will open a new pathway to implement IOT in day to day use. It will offer a large bandwidth and safe mediums for transmission and reception of data in contrast to RF-based communication.
