Building an ecosystem for Open 5G-campus networks with open radio technologies and interoperable components

The flagship project CampusOS was launched beginning 2022. The project is funded by the German Federal Ministry of Economic Affairs and Climate Action (BMWK) with 18.1 million euros over the next three years. CampusOS is coordinated by the Fraunhofer Institutes HHI and FOKUS, located in Berlin, Germany.

Project goal

The CampusOS project aims to create a modular ecosystem for open 5G campus networks based on open radio technologies and interoperable network components. This should enable more flexibility through manufacturer independence and more competition as well as innovation in order to strengthen the digital sovereignty of companies in Germany and Europe. 22 partners from industry and research examine different operator models, develop reference architectures, and evaluate interoperability and performance of the integrated solutions in reference test fields. Moreover, selected scenarios will be prototypically realized in the industrial environment as field trials.


Germany is a global pioneer in the operation of 5G campus networks, i.e. local and customer-specific 5G mobile networks. This advantage was achieved, among other things, by the Federal Network Agency's offer for dedicated campus network frequencies. The partners of the CampusOS project now want to further extend this lead by creating a digital ecosystem that ensures open radio technologies and interoperable network components. The ecosystem is to be realized in the form of a technology kit, which will be expanded by a component catalog and proposals for different operator models.

Thanks to network virtualization supplemented by artificial intelligence and machine learning, end devices as well as functionalities of the radio access network (RAN) and core network (CORE) can be combined dynamically and on demand to form a modular and secure 5G campus network. In order to test the new ecosystem, the CampusOS flagship project is setting up reference test fields at its locations in Berlin, Germany. The aim of these test fields is to evaluate  individual elements and various combinations of the technology kit for performance and interoperability before they are integrated into specific industrial field trials of  selected industrial use cases.
