Visible Light Communication

Visible Light Communication (VLC) is a technology that uses light, typically from LED bulbs, to transmit information. Unlike traditional wireless communications that rely on radio waves, VLC sends data by modulating the brightness of light, which the human eye perceives as constant. This method enables high-speed data transfer and can be used in various environments, especially where radio signals may be weak or interfere with other devices, such as in hospitals or airplanes. VLC offers a secure and efficient way to connect devices wirelessly through visible light, expanding the possibilities of wireless communication.
