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.

Conclusion The effectiveness of location-based services
is explained for visible light communication by showing some examples .
VLC can create a revolution in the area of consumer networking because of efficiency and affordability. It is expected that visible light communication will be widely used as LED light market expands worldwide.
