••• 14••• Innovationen Continued from page 1 At the end of October, the Bun- desnetzagentur published the fees for frequencies in the range from 3.7 GHz to 3.8 GHz for local applica- tions, thus laying the foundation for campus networks, i.e. a company’s own network on factory premises. Fraunhofer FOKUS discussed the technical implementation of such private networks with partners from industry and science at the Industrial IoT (IIoT) Forum and the FOKUS FUSECO Forum (FFF) and presented various 5G demonstra- tions for the factory of the future. Mostly wired industrial networks have been used in the last 50 years to meet high requirements regard- ing security, reliability and real- time behaviour. This has changed in recent years: The industry wants to benefit from the possibilities of worldwide digital networking in order to save costs or open up new business models. Wireless communication also offers greater flexibility within the factory prem- ises. Technically, this is being driv- en by the beginning convergence of classic operating technologies with modern ICT approaches. At the network level, the IEEE Time- Sensitive Networking (TSN) stand- ards and the 5G Ultra Reliable Low Latency Communications (uRLLC) specifications in Release 16 of the 3GPP standardization organization play a key role. At the same time, the German government supports the rapid, secure and cost-effec- tive construction of 5G networks on factory premises in line with individual requirements by allocat- ing local frequencies. Fraunhofer FOKUS and its part- ners demonstrated the technical possibilities of local 5G campus and TSN networks using various industrial applications as exam- ples. In many demonstrations the Open5GCore from Fraunhofer FOKUS is used as a software- based core network. The control programs for communication, as well as authentication and the connection of devices and servic- es, run in the core network. The software-based implementation allows network functions to be dynamically combined into one in- dividual, virtual campus network depending on the required laten- cy time, security level and number of devices to be networked. Two industrial cameras take 15 pictures per second of a screw. The video data is transmitted with a bandwidth of 16 bits to a com- puter, which then generates a 3D object of the screw in almost real time. The digital twin can be used for automated quality inspection or, in the event of irregularities, be forwarded to an inspector at another location for inspection and quality documentation. Visi- tors can slip into the role of the inspector and view the 3D model from all sides. The local 5G net- work ensures fast transmission of the high data volume. The demonstration shows a pro- duction line of a factory running on a local 5G campus network. The factory is represented in the demonstration by a Fischertech- nik model, on which the indus- try 4.0 value chain can be recon- structed. A digital twin is created to represent the complete pro- cess, document it and thus ensure higher quality standards. Recon- figurations of individual machines are possible thanks to the flex- ible IT network connection. A 5G core installation runs on a Hyper Converged Infrastructure from NetApp meeting performance, confidentiality, and reliability re- quirements. Using Virtual Reality (VR) glasses and two VR control- lers, visitors can control a two- armed industrial robot connected to an Edge-based 5G core net- work.
