What is “Visible Light Communication” ?

The visible light communication (VLC) refers to

the communication technology which utilizes the

visible light source as a signal transmitter, the air as

a transmission medium, and the appropriate

photodiode as a signal receiving component.

Visible Light

Visible Light SpectrumVisible Light Spectrum

Visible light is thus by definition comprised of visually-perceivable electromagnetic waves.

The visible spectrum covers wave lengths from 380 nm to 750 nm.

DrawbacksThe specific ports should be perfectly configured. LED and PD should be in the same line of sight.Distance between the transmitter and receiver should be small due lack of quality of LED and Photodiode.There should be no obstacle between the line of transmitter and receiver.
