Li-Fi is the abbreviation for Light Fidelity. Li-Fi is also an example of wireless networking technology like Wi-Fi. But Li-Fi is an optical networking technology which can be used to transfer data from one device to another by the use of visible light from LED. This is not like infrared networking technology which uses a visible light that can be seen by human eyes.
But Light Fidelity works by using an unsteady flash of light which can not be seen by human eyes. You can use Li-Fi for data transfer if your device is equipped with the capability to recognize the LED light signals and use them to transfer data. And it can only work if your device has a line of sight to the light transmitter. When using Li-Fi, you must avoid any form of obstruction in the path of the visible light. Li-Fi is also secure when compared to the cable way of transferring data.

The full form of LiFi is also known as Light Fidelity. This is a type of optical technology that allows the light coming from LED lights to be used for the transmission of data. It is important that the various devices that are being used in order to do this will be able to recognize the LED light so that they can continue with the rest of the transmission.
A lot of people say that they prefer using LI-Fi as compared to Wi-Fi which is considered to be more common simply because this can work faster as compared to Wi-Fi connections. Who does not want to transfer data in a fast and efficient manner, right?
