Why Open6GCore?
- Reusable software accumulated across 5G/6G research projects
- Faster integration of new technologies and prototypes
- Deep end-to-end observability and experimentation control
- Flexible 5G/6G research and testbed environment
- Existing integrations, interfaces and experimental capabilities
- Faster path from research idea to running experiment and evidence
What is Fraunhofer FOKUS Open6GCore?
Fraunhofer FOKUS Open6GCore is a continuously evolving software toolkit for advanced 5G/6G and future mobile network research.
It provides a running and configurable network environment for implementing new network functions, changing architectural concepts, integrating external technologies, and experimentally validating new approaches end-to-end.
Open6GCore grows through research projects. Reusable software, integrations and experimental capabilities developed in these projects remain available for subsequent work, allowing new projects to start from existing implementation experience instead of rebuilding the network environment from scratch.
Who is Open6GCore for?
Research the future network
- New network architectures and functions
- AI-native and agentic networks
- Automation and RAN-Core interaction
- ISAC and 5G PNT
- NTN, transport and deterministic networking
