WLAN and Bluetooth have limited bandwidth, making conventional wireless communication problematic in the production environment. Nevertheless, numerous components such as sensors and robots need to be wirelessly connected. To overcome this challenge, a team of researchers at Fraunhofer IOSB-INA in Lemgo is working on solutions with help from the Ostwestfalen-Lippe (OWL) University of Applied Sciences and Arts. Soon, it is hoped that machines in factory buildings will communicate with one another using light pulses. This technology is not new, but now it needs to be adapted for use in industry.
