VLC (Visible Light Communication)

Visible Light Communication (VLC) uses LED lights to transmit data by changing their brightness rapidly, in ways that are invisible to the human eye. When a light flickers at high speeds, it sends information to a receiver equipped with a photosensitive component. This technology leverages existing lighting infrastructure, like streetlights or indoor lighting, providing a dual purpose: illumination and data transmission. VLC offers high-speed, secure, and interference-resistant communication, making it suitable for applications such as wireless internet, smart homes, and vehicle-to-infrastructure links, all while utilizing the visible light spectrum instead of traditional radio waves.
