Chines Scientists Invented Lifi Technology Strong Alternative To ViFi

Successful experiments by Chinese scientists have indicated the possibility of the country’s netizens getting online through signals sent by lightbulbs (LiFi), instead of WiFi.

Four computers under a one-watt LED lightbulb may connect to the Internet under the principle that light can be used as a carrier instead of traditional radio frequencies, as in WiFi, said Chi Nan, an information technology professor with Shanghai’s Fudan University, on Thursday.


A lightbulb 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 LiFi research team including scientists from the Shanghai Institute of Technical Physics of the Chinese Academy of Sciences.
