a Internet, essential for digital transactions, is present in almost every home, office and coffee shop. It has definitely become an indispensable part of our daily life as it keeps us connected for work, learning, entertainment and much more.
In this context, Wi-Fi was the main way to access the Internet, our faithful wireless companion. However, with the rapid advancement in technology, even Wi-Fi, as amazing as it is, may give way to a more advanced technology – Li-Fi.

After all, what is Li-Fi?
Fidelity to Light (Li-Fi) is emerging as an exciting new technology star. Just imagine: instead of relying on traditional and sometimes unstable radio waves to transmit data wirelessly, Li-Fi uses the light emitted by LEDs for the task. Amazing, isn’t it?
It works like this: led lamps Flicker at a very high frequency (greater than 60 Hz), imperceptible to the human eye, transmits information. The receivers on the other side capture the photons of this flashing light and convert them back into data.
Not only does this technology have a cool factor, but Li-Fi signals can be hundreds of times faster than Wi-Fi signals!
Therefore, any place with a light source can become a Li-Fi hub. After all, its greater availability and lower cost make it an attractive option.
Large companies such as Philips are already exploring Li-Fi technology, while others are proposing innovative applications using Li-Fi to improve transmission by transmitting data through lamp posts, brake lights and vehicle headlights.
However, before you get too excited, there are some challenges in the way of Li-Fi. For one thing, there are no current devices that are compatible with this technology, which makes switching from Wi-Fi to Li-Fi an important transition.
Moreover, we cannot forget that the implementation of Li-Fi infrastructure requires a investment huge.
