Li-Fi refers to wireless communication systems using light as a carrier instead of traditional radio frequencies, as in technology using the trademark Wi-Fi.[1] Li-Fi has the advantage of being able to be used in electromagnetic sensitive areas such as in aircraft or nuclear power plants, without causing interference. However, the light waves used cannot penetrate walls which makes Li-Fi more secure relative to Wi-Fi. JUST WEEKS after Chinese researchers claimed that it would one day be possible to transmit WiFi from a lightbulb at up to 150Mbps, British boffins have smashed that target. The Ultra-Parallel Visible Light Communications Project - a joint team from several Scottish universities, Oxford, Cambridge and the Physical Sciences Research Council - has achieved 3.5GBps of the three primary colours from a small LED. Combined, this makes a total in excess of 10GBps of what is known as "LiFi". The modulation process, known as Orthogonal Frequency Divisional Multiplexing (OFDM) involves millions of changes in light intensity translated into the zeros and ones of digital communication. The news comes less than a month after German scientists achieved 1GBps under lab conditions, illustrating how fast this technology is developing. http://www.theinquirer.net/inquirer/news/2303456/lifi-breaks-the-10gbps-barrier
