Purpose and goal
3D-NET: 6G Integrated Satellite networks addresses satellite challenges by unifying terrestrial, non-terrestrial and airborne networks in a 3D architecture. The core objectives are optimization of communication and computing resources, energy-efficient operation, seamless mobility and handovers, robust positioning, and advanced edge/cloud integration. 3D-NET´s objective is to strengthen European sovereignty and leadership in sustainable, resilient and interoperable 6G satellite networks.
Expected effects and result
The project will deliver prototypes and realistic NTN demonstrations using VIAVI tools and Ovzon space networks, advancing 3GPP R19 technologies. KTH will develop novel aerial network architectures, mobility and interference management schemes, and intelligent 3D radio access solutions. The work strengthens Sweden’s broadband goals, enables new aerial services, and produces impactful research and education outcomes.
Planned approach and implementation
The project will integrate terrestrial, satellite, and airspace networks into a unified 3D-6G architecture. It will focus on joint orchestration of spectrum, compute, and power, seamless mobility across TN/NTN/air links, robust positioning, and standard-aligned 6G demonstrations. KTH will lead in architecture and AI-native RAN control, Ovzon will provide GEO capacity and OBP testing, VIAVI will deliver test tools, and Effnet will develop open O-RAN–based solutions.
