At our September Tech Talks we devoted the whole session to bringing us up to date on new developments in LiFi. Li-Fi utilizes light to transmit data between devices.This is in effect moving digital communication from the Microwave spectrum to the visible light spectrum. This is extremely interesting and has been made possible by the development of LED light globes. In terms of its end user, the technology is similar to Wi-Fi — the key technical difference being that Wi-Fi uses radio frequency to induce an electric tension in an antenna to transmit data, whereas Li-Fi uses the modulation of light intensity to transmit data. Li-Fi is able to function in areas otherwise susceptible to electromagnetic interference (e.g. aircraft cabins, hospitals, or the military).
