Data transmission via infrared light

Machines communicate by using infrared light
A distinguishing feature of industry 4.0 is the large amount of data generated when production processes are linked. Previously, data streams were sent primarily by cable, but this method is cumbersome when used in industrial processes and the cables are also prone to wear and tear. Transferring data using a wireless LAN is not a viable alternative because it is not fast enough. To solve this problem, engineers at the Fraunhofer Institute for Photonic Microsystems IPMS have developed a module that transmits data rapidly and securely using infrared light.
