In production environments it becomes more and more necessary being able to communicate wirelessly. Various mobile sensors exchange data with cloud servers in order to analyze the production process. However conventional mobile technologies lack bandwidth and the necessary quality of service due to a noisy and dynamic production environment. Today preprocessing and compression of the data stream are used to make these mobile applications functional, but this limits the applicability of in depth analysis by sensor fusion and machine learning mechanisms. In contrast, two upcoming wireless technologies pose promising candidate to solve this issue: The current version of 5G and the optical free space communication (OFSC) are both technologies, which are yet to be fully implemented. The next generation of mobile network (5G) aims at evolved radio communication properties of low latency and increased data rate, covering three application scenarios: Mobile broadband communication, massive machine type communication and ultra reliable low latency communication. OFSC on the other hand uses the license free, visible portion of the light, with the dual ability of illumination and simultaneous communication. Industrial environments hold a degrading effect on the OFSC quality, hence requiring special attention in the design. It can be deduced, that OFSC offers specific benefits compared to radio based communication technologies. The work derives a metric to compare the potential of 5G and OFSC directly based on the application example of a mobile data analysis application: A smart workpiece carrier “INAsense” moves through the entire production system, allowing an overall analysis. The production system is setup in the SmartFactoryOWL, which also uses a non public 5G network. The work highlights the industrial requirements, the principles of the respective wireless technologies, their current implementation state and further provides first experiences and a comparison in regards of the data application needs.
