Visible light communication (VLC), also called LiFi, 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. LiFi 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 LiFi systems and provides compact VLC modules for immediate industrial prototyping and field tests.
