August 1, 2024 – In the LINCNET project, Fraunhofer researchers are pioneering a new approach to data transmission using light. This innovation is aimed at improving data networks in industrial and clinical environments, where flexibility and security are paramount. Traditional Wi-Fi networks can interfere with one another, pose security risks, and emit electromagnetic radiation—issues especially relevant in settings like hospitals and factories. LINCNET addresses these concerns by transmitting data through light, reducing interference and enhancing security.

The key technology behind LINCNET is LiFi (Light Fidelity), which uses modulated light signals to transmit data wirelessly. By utilizing standard LEDs and photodiodes, this system offers robust and high-speed data transmission with latency under two milliseconds and speeds of up to 1 Gbps. An additional benefit is that light does not pass through walls, making the network highly secure and resistant to eavesdropping.

Fraunhofer’s approach combines the advantages of the 5G network with power line communication (PLC), using existing electrical infrastructure to carry data and transmit it via LiFi over short distances. This eliminates the need for additional cables and reduces electromagnetic emissions. In both industrial and medical settings, devices like robots and ultrasound machines can connect securely and wirelessly.

Fraunhofer’s research aims to scale these networks for real-time control in advanced manufacturing and healthcare. With support from the German Federal Ministry for Economic Affairs and Climate Action, the project is a significant step toward digitalization and technological sovereignty in Germany.
