We live in a technology era, technology always gets better than before. A new technology known as LiFi could one day offer speed more than 100 times faster than the WiFi we used the current time. This is a new revolution in technology.

What is LiFi?
LiFi can transfer data through LED lights and it 100 times faster than wifi we used today in our home.
LiFi is working like WiFi, but it uses LED bulbs rather than radio bands and waves.
Who Invented Li-Fi?
The Li-Fi technology was invented by German physicist Harald Haas in 2011.
How LiFi works?
LiFi works by flashing LED lights on and off at incredibly fast speeds, sending data to a receiver in binary code. It’s essentially an ultra-fast version of turning your flashlight on and off to create morse code. The flashes occur so fast that they are not seen by the naked eye. All one need to do is fit a small microchip to every potential illumination device and this would then combine two basic functionalities — illumination and wireless data transmission.
Harold Haas, one of the inventors of Li-Fi technology, has previously said that in the future every LED light bulb could potentially be used as an ultra-fast alternative to Wi-Fi.
“We have the infrastructure there,” Haas said in a TED Talk demonstrating Li-Fi. “We can use them for communications.
“All we need to do is fit a small microchip to every potential illumination device and this would then combine two basic functionalities: illumination and wireless data transmission.
“In the future we will not only have 14 billion light bulbs, we may have 14 billion Li-Fi’s deployed worldwide for a cleaner, greener and even a brighter future.”
