What is Li-Fi

Li-Fi stands for light fidelity, invented in 2011 by Harald Haas, a professor / engineer at the University of Edinburgh. It is also a wireless networking facility similar to Wi-Fi. Who is also the CEO of Purelifi.

Wi-Fi is based on Radio Frequency, in contrast Li-Fi is actually based on light, which is 100 times faster than Wi-Fi data sharing. - Able to provide. In Li-Fi technology, LED bulbs are used to exchange data, in this technique data is transferred by Visible Light Communication (VLC). Just like how your TV remote works.

One major advantage of the Wi-Fi technology is that it does not become a barrier to other radio signals like Wi-Fi. Therefore it can be used in places like airplanes where there is a problem of interference in the radio signal.

It also has a drawback, as this technology is based on light, so it is unable to penetrate a wall or any concrete object like a Wi-Fi signal.

Working Of Li-Fi 

It also works like all Internet devices. It has mainly used these three components:

1.Lamp driver
2.Led lamp
3.Photo detector

The internet source is connected to the Lamp Driver. Lamp Driver transmits the information that comes from Internet Cables within Led Bulb. After that, the light that comes in the Led Bulb is easily detected by the changes in the Photo Detector as soon as it collides with the Photo Detector.

Now Photo Detector Lights converts the signals to binary data. Then sends it to be processed on computer and smart-phone. Just as the data from the Lamp goes through the Lamp Driver and then from the Photo Detector to the mobile, in the same way the data from the Mobile can go back to the Receiver via the Led Lamp.

If you are standing under Light Source and even if you are moving then your connection will not be cut. If you move from one Light Spot to another Light Spot then it will automatically switch to another Light Spot.
