Visible Light Communication (VLC) is a technology using visible light as a signal transmitter, with air as a transmission medium and photodiodes as receivers. VLC offers high data speeds, human safety, and security, and has potential applications in networking, intelligent transport systems, and wireless communication. The VLC Consortium was established in 2003 to promote this technology, which has gained popularity in recent years.

- 3. What is VLC..??? 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.
- 4. Visible light is thus by definition comprised of visually-perceivable electromagnetic waves. The visible spectrum covers wave lengths from 380 nm to 750 nm.
- 16. The Visible Light Communications Consortium (VLCC) which is mainly comprised of Japanese technology companies was founded in November 2003. It increases the data speed compared to any communication
