LiFi internet that can boost your speed 100 times more than WiFi.
No one could have thought that one day the Light bulb would be used not only to illuminate home but also to transmit the data that would would enable people to download the big file in few minutes. The Li-Fi can boost your internet speed up to 100 times that of Wi-Fi.
Li-Fi was invented by Harold Hass of Edinburgh University in Scotland, 2011. It uses the concept of Visible light communication (VLC) to send data at extremely high speed. It works like a flashing a light on & off. It was found in previous testing that it can transmit about 224 gigabits/second.
This technology has been trailed by Estonian start-up Velmenni in offices and some other industrial settings in Tallinn. Here they were able to get speed around 1 Gigabits/second.
Apart from it's extremely fast speed it has also other benefits over Wi-Fi.
The very first thing is that the optical light can not travel through walls, therefore it enhance the security to your own networks.
While at the other hand it has also it's limitation as well, the connection will be lost it you leave the room. This can be a measure hurdle that must be overcome if this technology is to be successfully implemented.
According to Cisco Visual Networking Index Global Mobile Data Traffic Forecast, it found that the monthly data usage is expected to increase by 24.3 exabytes in 2019. This is a huge volume which a current wireless connections may not handle properly. So is they overcome the drawback then this technology can come with great future.
Harold Hass has recent asserted in " TED TALK that the LED lightbulbs can be easily converted into Li-Fi transmitters. All we need to do is fit a small microchip to every potential illumination device that can combine two functionalities Illumination & wireless days transmission and also said that In the future we will not only have 14 billon light bulbs but also 14 billion LiFis deployed worldwide for a cleaner, greener and even brighter future. "
Here given image below can give a idea how it is working.
