Understanding the Communication through Visible Light and its Application

Wireless optical technology like visible light communication is a new approach in terms of security, speed, usability, bandwidth and flexibility for data communication. More and more people with their devices access wireless internet today, due to which clogged airwaves are going to make transmission slow and is full of interference. The solution to this problem of slow speed is that data is to transmitted through light i.e. through” illumination” which means taking the fibre out of fibre optic and sending data through an LED light bulb that varies in intensity very quickly. It uses the similar idea that is used in infrared remote controls. Transmission through light is more powerful. This paper is the study of the transmission of data through light emitting diode i.e. visible light communication and its applications.
