3. The full meaning of li-fi is Light Fideality
LiFi is a wireless optical networking technology that uses light-
emitting diodes (LEDs) for data transmission. LiFi is designed to use
LED light bulbs similar to those currently in use in many energy-
conscious homes and offices.

4. History of Li-Fi
The technology truly began during the 1990’s in
countries like Germany, Korea, and japan where they
discovered LED’s could be retrofitted to send
information.
from the University of
Edinburgh

6. Operational procedure is very simple.
LiFi Design by light-emitting diodes (LEDs) for
data transmission.
 If LED is ON ,digital data ‘1’ is transmitted & if
LED is OFF, digital data ‘0’ is transmitted.
 LEDs varies in intensity so fast that a human
eye cannot detect it
 Also called as 5G optical communication.
