Review on Various Applications of Visible Light Communication

Abstract

In the current scenario, there is an increased usage of Radio Frequency (RF) for wireless
communication, that there is a major problem of bandwidth allocation. In order to overcome
this problem a new technology called Visible Light Communication (VLC) is introduced
which uses visible light whose data rates are higher than radio waves. Visible Light requires
fewer components than radio technology, hence cost effective. Data transmission requires
LED light sources which consumes less power. The data transmitted is more secure and can
be used in electromagnetic sensitive areas. This transmission technique can also be used in
aircraft cabins, hospitals and nuclear power plants without causing electromagnetic
interference.
