Visible Light Communication Applications and Challenges

Abstract

LEDs have replaced the florescent lamps in the field of solid state lighting at a rapid rate. They have higher energy efficiency, lower heat generation, improved color rendering and longer lifespan without using harmful chemicals. LEDs can switch to different light intensity at a faster rate. This great advantage of LEDs has been leading to a new communication technology known as Visible Light Communication. This paper provides a detailed survey of Visible Light Communication system, its characteristics and applications. The draw backs of the usage of LEDs in the vehicle to vehicle communication were overcome by Li-Fi technology. The application of LI-Fi technology in V-to-V communication is also discussed.
