Abstract:
The European 6G Flagship project Hexa-X-II created momentum around 6G via 44 member organizations covering the entire value chain. The project lasted from January 2023 until June 2025. Here the key findings of the project are summarized, including requirements for sustainable, inclusive and trustworthy 6G, end-to-end system view and architecture, its validation, enhanced connectivity via 6G, network sensing, compute and AI for novel digital services as well as efficient network realization, implementation and management.
