Li-Fi wireless communication technology is available, and its fastest test speed has reached 1Gpbs, which is 100 times
faster than Wi-Fi.
This technology, known as Li-Fi, transmits signals
by using light instead of radio.
Two competitive advantages of Li-Fi over Wi-Fi are speed and security
.
It is safer
because the light wave can be located more directly to the target device, and the beam cannot penetrate the wall and the signal does not leak.
Due to the focusing characteristics of light waves, there is little interference between signal transmission nodes; Coupled with the speed of photon propagation, Li-Fi can reach 100 times
the speed of WiFi.
Li-Fi wireless communication technology was invented by Professor Harald Haas of the University of
Edinburgh in 2011.
In laboratory tests at the University of Oxford, Li-Fi has reached a maximum speed of 224 Gbps
.
This Li-Fi wireless communication technology uses visible light from 400THz to 800 THz to transmit information through binary code, so 18 movies per second can be downloaded with a capacity of up to 1.
