Matsuda Posted October 28, 2013 Share Posted October 28, 2013 A group of UK-based researchers just had a breakthrough in their attempt to develop "visual light communication," a way to transfer data wirelessly over the internet using light bulbs.Scientists have announced data transfer speeds of more than 10 gigabits — about 10 times faster than a Google Fiber connection — using tiny LEDs that rapidly blink on and off to communicate in binary. The researchers used red, green, and blue micro-LEDs — the colors that make up white light — simultaneously, increasing the amount of information being transferred.The emerging technology is being hailed as a low-cost alternative to radio-based wireless internet, but it's uncertain how it would work in practice. The connection depends on the light traveling from the LEDs to a receiver without being interrupted, which means you'd better be careful not to walk between your laptop and the light source.The connection also can't penetrate through walls, which would seem to limit its applicability. However, scientists say this limitation could actually be a benefit for security, since wide-ranging Wi-Fi connections can be vulnerable to hackers.Despite the method's limitations, multiple groups have been working on visual light communication for more than 10 years. Earlier this month, a group of scientists in China claimed to have achieved speeds of 150 megabits using light. NASA is also working on a laser-based communications system that allows for internet connectivity between planets.View: Original Article Link to comment Share on other sites More sharing options...
