Li-Fi to replace Wi-Fi in China
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.
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 20 times faster than the average broadband connection in China.
