Li-Fi

Speed, it is what matters in this fast growing world.

Li-Fi a new wireless technology that will change the way you use Internet, Li-Fi is a wireless technology that transmits high-speed data using the Visible Light communication, they call it VLC.

Earlier this year scientists tested this technology in their labs and attain the maximum transmission speed up to 224 GB per second. Now the scientists are taking this technology in the world outside the lab for the first time.

According to the reports, the first ever test of Li-Fi in offices and industrial environment of Tallinn, Estonia they can achieve the maximum data transmission rate up to 1 GB per second which is 100 times faster than the average Wi-Fi speed.

The CEO of Estonian tech Company, Velmenni told to IBTimes UK “Currently we have designed a smart lighting solution for an industrial environment where the data communication is done through light. We are also doing a pilot project with a private client where we are setting up a Li-Fi network to access the Internet in their office space.”

Invention of LI-Fi

Li-Fi was invented by Harald Hass of University of Edinburgh, Scotland back in 2011. He showed for the first time that how he can transmit far more data than a cellular tower just by flickering the light from the single LED. LI-Fi uses Visible Light Communication (VLC). VLC is a medium that uses visible light between 400 and 800 THz. It works on the principle of transmitting the secret message by flicking a troch on and off. Similarly binary codes can also be transferred by flicking the LED ON and OFF. And obviously the flicking of light is very fast that it is imperceptible to the naked human eye.

Benefits of Li-Fi

  • It is much faster than the current Wi-Fi technology.
  • As the light cannot pass through walls, it makes it whole lot more secure.
  • Less interference between the devices

Anthony Cuthbertson says Li-Fi will probably not replace the Wi-Fi in future but it can be used along with the Wi-Fi to attain much more secure and faster networks.
