Dear Wifi, We had a nice time together, but being faithful will be too much to ask now that Li-Fi is looking super cute without the aid of Make-up.
Scientists have performed real-world tests of a new form of data transmission called “Li-Fi”, and achieved massive speeds – about 100 times faster than the average Wi-Fi.
The team at Estonian tech startup Velmenni ran the pilot tests as part of their research into developing smart LED light bulbs. In offices and industrial environments, Li-Fi managed to transmit 1GB of data in a single second. That’s almost the equivalent of downloading a HD movie.
The tech’s official name is visible light communication or VLC, but it’s gained the nickname of Li-Fi to reflect the fact that it uses light to transmit data. It was first invented by Harald Haas at the University of Edinburgh in 2011, who demonstrated that an LED light flickering at super high speeds was capable of transferring more data than the average mobile tower. The bulbs use visible light at frequencies of 400-800THz, and flicker on and off in binary code – and they do it fast enough that it can’t be seen by the naked eye.
Since its invention, lab tests have recorded staggering transfer speeds of 224Gb (about 18 HD movies in a second), but these results from Velmenni are the first from testing the tech in real-world environments.
Deepak Solanki, Velmenni CEO, said: “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.”
The only problem with Li-Fi is that its reliance on visible light means it can’t work through walls, However, Harald Haas says that’s easily solved by having an LED light bulb in every room – so keep your eyes peeled as the tech develops.
