100 times faster than Wi-Fi: Introducing Li-fi
Imagine getting into bed at night with the intention to watch a movie till sleep comes, you decide to click on the download button just before rolling over to the wall-side of your bed to turn off the lights, and zoom, your 1GB movie series has finished downloading. Stuff of dreams right? That’s exactly how fast the latest wireless internet technology, called Li-fi is.
Li-fi, according to PC Advisor, was discovered by a German physicist, Harald Hass, who has since collaborated with a team of researchers from the University of Edinburgh to develop it further into what is now known as Pure Li-fi.
It uses light, instead of radio waves, to transmit data through the air. Hence, it is reported to be 100 times faster than Wi-Fi; but therein also lies it limitation – light cannot travel through walls…
What does the future hold for Wi-Fi?
Therefore, the early good news for poor old Wi-fi is that it will not be completely rendered obsolete. Instead, it will still be needed to complement Li-fi in totally partitioned closed spaces.
We at IR think Li-Fi is a cheeter while Wi-fi is a toddler – not even Usain Bolt.
