Visible Light Communication [VLC] and its Applications

The communication using visible light is the new trend in communication field where the different coloured light or different intensity of light is used to communicate.Why the visible light communication is more important in this era?It is because the already existing communication method has some difficulties and interference.The most of the existing communication systems uses radio frequency.In radio communication, information's such as sound, images are carried by radio waves.But this Radio Frequency [RF] communication has some disadvantages.It suffers from interference and high latency issues and the RF communication requires a separate setup for transmission and reception of radio waves.For overcoming these limitations, a new method is adopted ie, Visible Light Communication [VLC].
