Review on Various Applications of Visible Light Communication

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
