CSK Fan Posted October 17, 2013 Posted October 17, 2013 New discovery dubbed as 'Li-Fi' to replace Wi-Fi in China? http://economictimes.indiatimes.com/tech/internet/new-discovery-dubbed-as-li-fi-to-replace-wi-fi-in-china/articleshow/24287691.cms BEIJING: Chinese scientists have successfully developed a new cheaper way of getting connected to internet by using signals sent through light bulbs instead of radio frequencies as in 'Wi-Fi', a move expected to radically change process of online connectivity. Four computers can be connected to internet through one- watt LED bulb using light as a carrier instead of traditional radio frequencies, as in Wi-Fi, said Chi Nan, an information technology professor with Shanghai's Fudan University. Under the new discovery dubbed as 'Li-Fi', a light bulb with embedded microchips can produce data rates as fast as 150 megabits per second, which is speedier than the average broadband connection in China, said Chi, who leads a Li-Fi research team including scientists from the Shanghai Institute of Technical Physics of the Chinese Academy of Sciences. The term Li-Fi was coined by Harald Haas from the University of Edinburgh in the UK and refers to a type of visible light communication technology that delivers a networked, mobile, high-speed communication solution in a similar manner as Wi-Fi. With Li-Fi cost-effective as well as efficient, netizens should be excited to view 10 sample Li-Fi kits that will be on display at the China International Industry Fair that will kick off on November 5 in Shanghai. Compared with base stations, the number of light bulbs that can be used is practically limitless.
akshayxyz Posted October 17, 2013 Posted October 17, 2013 Cant be as trivial as using 'light', as visible light get blocked easily.
diga Posted October 18, 2013 Posted October 18, 2013 @MTC: Thats already in works & is not exactly a chinese concept.. Did you assume its chinese as there was a Li :--D? No chinese company is a founding member of Li - fi consortium & the term was invented by a Brit.. It needs G.HN to work which is still under development
Clarke Posted October 18, 2013 Posted October 18, 2013 Recycling seems to be big there. Next up, they'll come up with "broadband via power lines".
