Wireless Audio Transmission using Li-Fi
Introduction to Li-Fi
Li-Fi (also written as LiFi) acronym for Light Fidelity is a wireless communication technology that utilizes light to transmit data and position between devices. It is capable of transmitting data at high speeds over visible light, ultraviolet, and infrared spectrums. In its present state, only LED lamps can be used for the transmission of data in visible light. In terms of its end-use, the technology is similar to Wi-Fi — the key technical difference being that Wi-Fi uses radio frequency to induce a voltage in an antenna to transmit data, whereas Li-Fi uses the modulation of light intensity to transmit data. Li-Fi can theoretically transmit at speeds of up to 100 Gbit/s. Li-Fi’s ability to safely function in areas otherwise susceptible to electromagnetic interference (e.g. aircraft cabins, hospitals, military) is an advantage. The technology is being developed by several organizations across the globe.”
