With just over five million residents, Finland stands at the forefront of 6G innovation with the pioneering 6G Flagship programme. This groundbreaking initiative, housed at the University of Oulu, serves as a beacon for the future of 6G technology. Supported by the Research Council of Finland, the programme is a key player in driving long-term research aligned with the country’s innovation agenda.
When people ask how the University of Oulu and 6G Flagship connect to Europe’s 6G work, Professor Ari Pouttu, the Director of 6G Flagship, points them to the Smart Networks and Services Joint Undertaking. This collaboration positions the University of Oulu at the forefront of European 6G initiatives, actively contributing to projects like Hexa-X-II and 6G-SANDBOX. The university’s involvement in 16 SNS JU projects underscores its commitment to advancing 6G technology beyond theoretical research.
Finland’s Ecosystem
6G Flagship provides a unique platform for companies in Finland to test and refine their products in preparation for future networks. By offering access to cutting-edge facilities and expertise, the programme enables both startups and established corporations to experiment and innovate in a collaborative academic environment.
For smaller firms, access to the test network can be a game-changer, allowing them to validate their ideas in real-world conditions and adapt to emerging industry standards. Director Ari Pouttu emphasizes the importance of this opportunity for startups, highlighting the difference it can make in the success or failure of a new concept.
Strategic Research Areas
At the core of 6G Flagship are four strategic research areas led by distinguished professors in the field. These areas encompass the entire spectrum of wireless connectivity, from fundamental theory development to hardware design, distributed intelligence, and human-centric wireless services.
Professor Markku Juntti spearheads the wireless connectivity research area, focusing on developing future wireless access and networking solutions to support new 6G use cases. The goal is to enable sustainable and resilient connectivity for applications like networked AI and integrated sensing and communications.
Under the guidance of Professor Aarno Pärssinen, the device and circuit technology research area translates key concepts into practical hardware solutions. Leveraging Finland’s rich history in radio engineering, the group designs circuits and subsystems capable of operating at frequencies beyond current limits.
Associate Professor Miguel Bordallo López leads the distributed intelligence research area, which integrates computer vision, AI, and wireless systems to enable real-time decision-making at the network’s edge. By fusing multimodal data, the research aims to embed intelligence in critical sectors like healthcare and transportation.
The 6G Test Centre
The 6G Test Centre in Oulu serves as a hub where research concepts meet real-world challenges. Equipped with advanced testing capabilities and a diverse range of testing environments, the centre allows researchers to evaluate new technologies in urban, rural, and extreme conditions.
Director Hannu Nikurautio highlights the centre’s role in providing companies of all sizes with access to state-of-the-art equipment and expertise for testing next-generation wireless technologies. The facility’s unique capabilities have positioned it as a leading academic environment for wireless technology research and development.
Resilience as a Design Principle
As the landscape of communication networks evolves, resilience emerges as a critical design principle for 6G technology. Professor Ari Pouttu emphasizes the importance of building resilience into network architectures to withstand environmental disasters, cyber-attacks, and other threats.
By incorporating mesh networking, distributed intelligence, and local energy supply into network designs, researchers at 6G Flagship are working towards creating systems that can adapt to unforeseen challenges and recover quickly from disruptions. The focus on resilience reflects a shift in mindset towards building robust and reliable networks that can support critical sectors like power grids, healthcare, and finance.
The upcoming Resilience White Paper, set to be launched at the 6G Resilience Summit in Oulu, will further underscore the importance of resilience in shaping Europe’s digital future. For Professor Pouttu, resilience is not just a technical requirement but a cornerstone of societal sustainability and security.
