Europe’s strategic leap into the future of connectivity

Imagine a world where critical surgeries are performed remotely, in real time, without a hint of delay. Where autonomous vehicles make split-second decisions based on vast flows of data, and students attend lifelike holographic classrooms from remote regions or distant continents. These scenarios, once from science fiction, are already being envisioned within the framework of the next generation of mobile networks: 6G.

From the perspective of ongoing EU research and innovation programmes focused on digital technologies, 6G can be perceived 6G not merely as a technological progression, but as a pivotal moment for how Europe intends to shape its digital sovereignty. The policy and funding decisions made today will significantly influence the networks on which we will rely in the decades to come.

While 5G came with notable advancements in speed and connectivity, 6G responds to a new wave of technological and societal demands. The explosion of data, the incorporation of artificial intelligence into network operations, and the need for ultra-reliable and low-latency communication collectively create the need for the development of a more advanced network infrastructure. 6G aims to support applications such as digital twins, extended reality, autonomous systems, and precision healthcare.

The technological pillars of 6G include the use of terahertz frequencies for ultra-fast data transmission, AI-native architectures that enable real-time optimisation, integrated network sensing capabilities, and quantum communications for enhanced security. Furthermore, the convergence of edge and cloud computing will allow for efficient data distribution and timely responsiveness.

Embedding AI at the core of the network represents one of the most profound shifts—ushering in self-optimising, context-aware systems that go well beyond today’s capabilities. Such technological advances are being strategically coordinated through major European research and investment initiatives.

Major European projects in 6G networks

The European Union is supporting this transition through coordinated programmes under Horizon Europe and the Digital Europe Programme. Central to these efforts is the Smart Networks and Services Joint Undertaking (SNS JU), a public-private partnership initiated in 2021. With a combined investment exceeding €1.8 billion, SNS JU is advancing Europe’s leadership in 6G research, innovation, and standardisation.

A flagship project within this ecosystem is Hexa-X, the EU’s first 6G research initiative, which ran from 2021 to 2023 under Nokia’s coordination. Comprising 25 partners from academia and industry, Hexa-X aimed to define the initial vision, key use cases, and technological building blocks of 6G. Its scope included explorations of terahertz radio access, AI integration for network intelligence, and conceptualisations of applications in smart environments and robotics.

To build on these foundations, the EU launched Hexa-X-II in 2023, expanding the consortium to 44 partners. This project seeks to design a full end-to-end 6G system architecture, incorporating communication, sensing, and computing. Notably, Hexa-X-II places a strong emphasis on embedding European principles—trust, sustainability, and inclusion—into the very design of future networks, thereby ensuring alignment with EU values and long-term strategic goals.

Complementing these efforts, the 6G-Sandbox project is creating a pan-European test infrastructure, with sites in Spain, Finland, Greece, and Germany. This initiative enables real-world testing of 6G technologies and serves as a crucial bridge between theoretical research and practical deployment. Additional projects, such as Terrameta and 6G-NTN, focus on specific challenges including the development and the integration of non-terrestrial networks, such satellites and high-altitude platforms, into the broader 6G ecosystem.

On the global stage, 6G has emerged as a critical domain for technological and economic leadership. Countries such as China, the United States, South Korea, and Japan are investing heavily to shape the direction of global 6G standards and deployments. China currently leads in 6G patent filings and is planning initial trials by 2025. South Korea’s K-Network 2030 strategy targets commercialisation by 2028, while the United States supports 6G development through initiatives like the Next G Alliance and investments under the Chips Act.

Impact of 6G on digital sovereignty

Europe’s approach is distinct in its emphasis on openness, ethical governance, and policy alignment. While maintaining cooperative frameworks with global partners, the EU is simultaneously reducing strategic dependencies and reinforcing internal technological capacity. Initiatives that combine microelectronics, edge computing, and trustworthy AI reflect this integrated vision of digital sovereignty.

Crucially, the European vision for 6G extends well beyond technical specifications. It is rooted in the ambition to build a network that is secure, accessible, and environmentally responsible. Projects funded through SNS JU explicitly prioritise these aspects from the outset, embedding sustainability and inclusion into their core principles.

For instance, 6G technologies are expected to play a key role in supporting the European Green Deal by enabling more efficient energy grids, facilitating large-scale climate monitoring, and supporting greener industrial processes. Moreover, by addressing coverage gaps in rural and underserved regions, 6G infrastructure aims to reduce the digital divide and ensure equitable access to advanced services across all communities.

The journey towards 6G involves complex challenges, including regulatory harmonisation, large-scale infrastructure investment, and workforce development. Nonetheless, the European Union has already laid robust foundations, with over 80 research and innovation projects either completed or underway. These efforts are collectively steering Europe toward a targeted deployment by 2030.

As standardisation advances and pilot implementations begin, Europe’s commitment to a secure, inclusive, and sustainable digital future will come into sharper focus. If these efforts maintain their current trajectory, 6G could well emerge as a defining success of the European Digital Decade as not only transforming connectivity, but reshaping how we live, interact, and innovate in the years ahead.
