WiFi technology to be replaced by LiFi Technology soon!

Light Fidelity, shortly known as LiFi is all set to replace WiFi technology in near future. As per our media sources, researchers have achieved speeds in the lab of up to 224GB/sec transfer with LiFi. This means, users can download almost 12-15 HD content movies with just a blink of an eye.

LiFi is already being tested in Tallinn, Estonia and is said to have achieved speeds of up to 1GB/sec so far, which is more than 100 times the speed of traditional Wi-Fi.

It is estimated that by 2019, the world will be exchanging roughly around 35 quintillion bytes of information each month- all thanks to Internet of Things. As radio frequencies are restricted, Wifi will be the only option left to exchange data. But the speeds at which it can deliver data is not as per the expectations of changing trends.

This is where LiFi will act as a boon and to know how it works, please follow the next few lines of this article.

Like radio waves, visible light is part of the electromagnetic spectrum. The difference is that viable light has a spectrum 10,000 times larger than radio waves. This means LiFi has the potential for enormous capacity. Instead of transmitting information via one data stream, visible light would make it possible to transmit the same information using thousands of data streams simultaneously.

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 (which is an alphabet or code in which letters are represented by combinations of long and short signals of light or speed). 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.

In other words, the infrastructure is already there. The other good news is that we can use the LED bulbs we already have, with some tweaking.

So, get ready to experiment guys!
