Researchers around the world are developing light-fidelity (Li-Fi) technology (the use of light to exchange large amounts of data) to augment, or sometimes replace, the widely used Wi-Fi. Developers at Fraunhofer IPMS (Dresden, Germany) are working on Li-Fi systems specifically for use in industrial environments. The use of Internet of Things (IoT) technology in industry is known as Industrial Internet of Things (IIoT) or Industry 4.0.
In addition to allowing different users in an industrial setting to simultaneously use an access point, the IPMS-developed optical transmission technology enables each user to communicate with several access points. As a result, Li-Fi is no longer limited to stationary applications. Fraunhofer IPMS specialists will present this multipoint-to-multipoint-capable technology to the professional public for the first time at the 2017 SPS IPC Drives Trade Fair for Electric Automation (Nuremberg, Germany; November 28-30, 2017).
