Eight years of Finnish 6G

The University of Oulu’s 6G Flagship research programme has published the twelfth and final issue of 6G Waves, a magazine documenting how next-generation wireless research is moving from vision to real-world validation. The issue explores resilient communications, AI-native radio networks, Arctic testing, open-source innovation and European collaboration shaping the path toward 6G. The key achievements of the journal and the research program are presented today at the major 6G Summit at Finlandia Hall in Helsinki.

6G Flagship is the world’s first 6G research programme, based at the University of Oulu in Finland. Funded by the Research Council of Finland, it develops the scientific foundations for future wireless technologies through international research, industry collaboration and advanced test infrastructure.

As the 6G Waves magazine concludes its publication run, its central message is forward-looking: 6G research continues. The issue examines the growing need for communications infrastructure that can sustain critical services through disruptions, including cyberattacks, power failures, extreme weather and contested operating environments.

Testing in real conditions

The magazine highlights practical demonstrations from the University of Oulu’s 6G Test Centre, including airborne local 5G coverage for disaster scenarios, off-grid radio sites designed for polar conditions, signal redirection using reconfigurable intelligent surfaces, and radio tomography at 300 GHz. It also reports on a new NVIDIA AI Aerial platform integrated into Oulu’s live 5G Test Network, enabling researchers to develop and evaluate AI-RAN technologies on an operational radio stack.

The issue details Finland’s €4.8 million investment in Arctic and operational validation for resilient 5G and 6G systems. This work links laboratory research with outdoor and field-based testing, including hybrid terrestrial-satellite connectivity, deployable networks, edge computing and connected uncrewed systems.

The magazine also explores Europe’s collaborative 6G research model. The University of Oulu contributed to five of ten results recognised by the EU’s Smart Networks and Services Joint Undertaking, including projects on sustainable battery-free IoT, holographic communications, cross-border experimentation and 6G architecture.

The final issue points out the 6G Flagship’s achievements from May 2018 through June 2026 in numbers: 4875 peer-reviewed publications, 188 doctoral degrees, 527 company collaborators and more than 1.1 million downloads of its 6G White Papers. The programme involved 525 experts representing 46 nationalities in 2026.

The number of doctoral theses produced accounts for well over 10 percent of the total number of doctoral degrees awarded annually at the University of Oulu. This represents an exceptionally significant impact on doctoral education for a research programme. The majority of these doctors (53%) continue to reside in Oulu, and three-quarters are employed in Finland.

The magazine also addresses the evolving priorities for future networks: AI integration, sustainability, privacy, sensing, trusted connectivity and resilience. While the formal 6G standard is expected to mature before the 2030s, the University of Oulu has committed to continuing its 6G research through 2030.

“The print run ends, but our channels remain wide open,” write the editors Katja Longhurst, Ville Wittenberg and Sallamaari Syrjä in the foreword.

What is happening at the 6G Summit 2026 and why does it matter?

The 6G Summit 2026, at Finlandia Hall in Helsinki, brings together leading researchers, technology companies, policymakers and funding organizations from Europe and the United States to discuss the future of 6G and wireless intelligence. The event is organized by Business Finland’s 6G Bridge programme and the University of Oulu’s 6G Flagship.

The timing is particularly significant because many of the first major 6G research programmes are now reaching maturity. The summit serves as a platform to present key results, identify future research priorities and strengthen international collaboration as the global 6G race enters a new phase.

Discussions will focus on some of the most pressing topics shaping future digital infrastructure, including artificial intelligence in networks, European and transatlantic cooperation, resilience and security, sustainability, space-based connectivity, and the growing geopolitical importance of communications technologies. Speakers include representatives from Nokia, NVIDIA, the European Space Agency (ESA), the U.S. National Science Foundation, the European Commission’s Smart Networks and Services Joint Undertaking, and the Finnish government.

The summit is important because 6G is no longer only a research vision. Decisions made today on technology development, standards, regulation and investment will influence future communication networks, digital competitiveness, industrial innovation and societal resilience for decades to come. The event highlights Finland’s leading role in global 6G development and provides a forum where industry, academia and policymakers can jointly shape the next generation of wireless technologies.

A wrap-up

The 6G Summit 2026 brings together international leaders from industry, research and government to discuss the next phase of 6G development. As major 6G research programmes reach key milestones, the event provides a forum for presenting results, shaping future priorities and strengthening global cooperation. Discussions will focus on AI-powered networks, resilience, sustainability, security and the future role of communications technologies in society and the economy.
