LiFi, or Light Fidelity, is an optical telecommunications technology that transmits information by modulating a visible light source. Standardized since 2011, and associated with the intensive deployment of LEDs, this technology offers performance potential that makes it an excellent communications medium, complementing radio frequency technologies. The components of a LiFi transmission chain are similar to those of a fiber-optic chain, with the added concern of being free from environmental conditions generating disturbances, given the optical band used. There are numerous applications, both inside buildings, where LEDs are becoming the standard, and outside...
