China: Shanghai Institute of Technical Physics of the Chinese Academy of Science has made-up a Li-Fi device which will replace Wi-Fi soon.
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.
