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.

10. VISIBLE LIGHT COMMUNICATION
PROCESS

11. Transmitters:-
•LED
•Fluorescent Light

13. Receiver:-
•Photodiode

14. LED Technical Evolution

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

17. •Human Safety
•High Data Rate
•Bandwidth
•Security
•Visibility
•Unlicensed Spectrum

18. •Limited Transmission Power
•Regulated Spectrum:
•Banned in Sensitive Areas

20. • Position Detection
•Intelligent Transport System
• Image Sensor Communications
• Networking
• Audio Applications

21. •LED can be used not only for lighting the
homes but also as means for wireless in-
house communication.
After few years the VLC is become more
popular
