Velmenni, an Estonian startup, recently announced that they have installed Li-Fi, a faster alternative to Wi-Fi, in offices and industrial spaces in Tallinn. Li-Fi, in Velmenni’s trials, was able to send data at more than 1Gbps, which is more than a hundred times the speed of Wi-Fi. According to Deepak Solanki, Velmenni’s CEO, Li-Fi utilizes visible light technology (VLC), which allows for greater security on local networks (since light cannot pass through walls), and less interference between local devices.

Li-Fi, according to analysts, may never completely replace Wi-Fi, but it is possible that the two technologies could work together to create more efficient networks. Before this can become a reality, however, current devices would have undergo major transformations to work with Li-Fi. Harald Hass, the professor at the University of Edinburgh who invented Li-Fi, does claim that LED lightbulbs would one day be used as Li-Fi transmitters, combining, he said, “two basic functionalities: illumination and wireless data transmission.”
