Visible Light Communication (VLC) is a wireless mode of communication that provides for high-speed transmission of data with light being possible. This mode of data exchange is new in technology and depends on intense optical modulation.
It is applied primarily to underwater divulgence, vehicle-to-vehicle conveyance, inside a plane, or broadcasting systems for internet operation. The method requires the receiver to use a photo diode to retrieve a message. The sender and the recipient should be in Light of Sight to make the process effective and efficient.
Some of the advantages of using VLC is that it is very easy to install. No records of health risks to the users or human beings generally. It is efficient regarding power since its source is for both communication and illumination, thus consuming low energy.
This methodology is used when both the recipient and the sender are in the same room, minimizing the chances of interception by anyone and providing security. It supports a massive amount of data transmitted in a given internet connection and time, also known as bandwidth. It is light-based and, therefore, not affected by Radio Frequency radiations.
VLC is transmitted at high speed and can only be measured by timing the delay of a pulse or Light Emitting Diodes (LED) reflection. It can be used as a medium of communication for universal computing.
This is because devices that produce light are used everywhere, like traffic signs, commercial displays and advertisements, TVs, car headlights, and outdoor or indoor lamps. Their measurements depend on results that are calculated analytically.
