Estonia-based company Velmenni has successfully tested a new type of internet connection called Li-Fi that is capable of internet speeds up to 1 gigabyte-per-second, or around 100 times faster than the Wi-Fi connection we use now.
Li-Fi is based on a visible light communication (VLC) technology created in 2011 that transmits information using LED lights that flicker on and off in a matter of nanoseconds. The flicker is so fast to humans that it appears as if the light remains on. Because it is based on light, Li-Fi can’t penetrate walls like Wi-Fi can, but the method may increase the security of your information from wireless hacking attempts.
In a lab setting, Velmenni has been able to reach data transfer speeds at an astonishing 224 gigabytes-per-second. Because it is based on light, a high-tech LED lightbulb could establish an internet connection as well as light up the room.
Deepak Solanki, the CEO of Velmmeni, told IBTimes UK that the technology could hit consumers within the next three to four years.
Professor Harald Haas of the University of Edinburgh, the inventor of Li-Fi, described elegance of the technology in a TED talk in 2011.
“All we need to do is fit a small microchip to every potential illumination device and this would then combine two basic functionalities: illumination and wireless data transmission. In the future we will not only have 14 billion light bulbs, we may have 14 billion Li-Fis deployed worldwide for a cleaner, greener and even brighter future.”
