Imagine using your car headlights to transmit data ... or surfing the web safely on a plane, tethered only by a line of sight. Inventor Harald Haas has been working on this for some time now. He currently holds the Chair of Mobile Communications at the University of Edinburgh, and is co-founder and Chief Scientific Officer of pureLiFi Ltd as well as the Director of the LiFi Research and Development Center at the University of Edinburgh. Over time researchers have achieved speeds of 224 gigabits per second using Li-Fi under laboratory conditions, which would theoretically allow for 18 HD movies to be downloaded in a single second. Other advantages it holds over Wi-Fi are less interference between devices and improved security over local networks, as light cannot pass through walls. Harald Hass first introduced Li-Fi to the world back in 2011 at a TED conference as is presented below. It's a technology that may end up in a future iPhone which makes this video all the more appealing.
This week an older tweet dating back to December showed iOS 9.1 firmware that pointed to 'LiFi Capability.' During the TED keynote, Harald Haas said it could be possible to build Li-Fi into a smartphone camera, using its LED lighting.
Li-Fi, often referred to as the next big leap in wireless data transfer, could offer speeds up to 100 times faster than Wi-Fi. Haas ended his keynote saying that using Li-Fi could lead to a cleaner, greener and brighter future which is something that Apple believes in with a number of solar projects (one, two and three) that they've been involved with over the years. Is the market really ready for Li-Wi? Only time will tell.
