Visible Light Communication

Visible light Communication (VLC) creates technology revolution in network sector. In this technology, visible light is used to transmit or receive data. In this paper, OOK [ON-OFF keying] modulation is used to send and receive data& #039, s using LED lights and the audio signal is transmitted through 1W LED and received by solar cell and the played in loudspeaker. It does not require front end and receiver end antenna and any light emitting devices with faster switching rates can be converted into internet modem with small integrated chip. It has very wide range of applications apart from the internet such as traffic management and places where RF radio waves are restricted.
