With technologies like 802.11ac, we're transferring data over the air at fantastic speeds. However, Professor Harald Haas, hailing from the University of Edinburgh, has invented Li-Fi, which uses visible light communication or VLC, to transmit data wirelessly at even higher speeds. In its current iteration, Li-Fi uses LED lights, which flicker at a rate that is imperceptible to the human eye, to transmit data. Researchers from the University of Oxford were able to hit bi-directional Li-Fi speeds of 224 Gbps earlier this year in a lab setting. To put that in perspective, those speeds would allow 18 high definition movies to be download in a just one second. In addition, researchers at Velmenni based in Estonia have moved past lab trials onto a pilot program which uses an even faster version of Li-Fi in a commercial setting. Instead of mere 224Gbps speeds, Velmenni was able to top 1 GBps, roughly 100 times faster than current Wi-Fi technology.
