Indoor Li-Fi

Visible light communication (VLC), also called Li-Fi, is an interesting alternative for mobile communication via light. The already existing LED illumination infrastructure can be reused and new high-speed data transmission functionality is added. Li-Fi is considered as a promising technology for mobile indoor connectivity where the unlicensed optical spectrum is used. Light is better confined compared to radio and safer against unauthorized access and jamming. Secure high-speed light communication will enable new use cases especially in enterprise scenarios. Fraunhofer HHI has more than 20 years of experience on indoor Li-Fi systems and provides compact VLC modules for immediate industrial prototyping and field tests.
