Li-Fi for Industrial IoT

At a Glance

Fraunhofer HHI has more than 20 years of experience on Optical Wireless systems and provides compact communication modules for immediate industrial prototyping and field tests.

Technical Background

Optical Wireless Communication (OWC) offers mobile high speed data transmission via light. The LED based systems use unregulated optical (visible or near infrared) spectrum. As light does not pass through walls, enhanced security is achieved. Dense user scenarios, easy small cell deployment and interference-free operation to existing radio wireless systems are possible. OWC is well suited for numerous use cases like Industrial Wireless, Mobile Front- and Backhauling and Indoor Li-Fi.
