Harald Haas

Harald Haas is a German engineer known for developing VLC (Visible Light Communication) technology, which uses LED lights to transmit data. Instead of relying on Wi-Fi or radio signals, his innovation allows light bulbs to send information at high speeds, enabling high-quality internet connections through existing lighting systems. This approach offers a secure, energy-efficient way to enhance wireless communication, especially in environments where radio signals are limited or undesirable. Haas's work has potential applications in homes, offices, and cities, making indoor data transmission faster and more secure by harnessing the power of visible light.
