European firms are pioneering 6G networks by enhancing RF technology and IoT connectivity to meet regional communication needs.

Major European Research Initiatives

The 6G European Smart Networks and Services Joint Undertaking made significant strides in 2024, launching 28 research and innovation programs in January under Horizon Europe [2]. This initiative has particularly focused on integrating artificial intelligence with next-generation wireless networks, emphasizing the development of reconfigurable intelligent surfaces (RIS) and integrated sensing and communications (ISAC) to enhance data reliability and sensing accuracy [4]. A groundbreaking collaboration between EU and U.S. partners, the 6G-XCEL project, is working to establish an advanced supply chain for 5G and 6G systems [2], with particular emphasis on network resource sharing and open-source implementation.

Technical Breakthroughs in Network Architecture

Recent developments have centered on energy efficiency as a key performance indicator for 6G networks [4]. The integration of Reconfigurable Intelligent Surfaces has emerged as a paradigm shift in wireless communications, offering significant advantages including reduced costs and environmental benefits [5]. In December 2024, researchers demonstrated notable progress in multiband capabilities through the publication of ‘Multiband In-Band Full-Duplexing Using Fractal Concentric Circular Antenna Arrays’ [4]. These advancements are particularly focused on enabling ultra-high data rates in both cmWave (7-15 GHz) and terahertz bands [3].

Security and Integration Challenges

A critical focus of European 6G development has been the integration of terrestrial and non-terrestrial networks, creating comprehensive air-space-ground-maritime coverage [6]. This expanded service coverage extends from traditional two-dimensional terrestrial space to three-dimensional near-Earth space, presenting new security challenges [6]. Researchers are actively developing innovative solutions for information security, including covert communication techniques and encryption strategies, essential for protecting against interference attacks and information leakage in these complex integrated networks [6].

Future Outlook and Industry Collaboration

Industry panels held at the 2024 IEEE GLOBECOM conference in December highlighted the increasing focus on network resilience as a core property of 6G infrastructure [5]. Leading experts from institutions including TU Berlin and TU Dresden emphasized the critical role of machine learning in enhancing network resilience [5]. The European telecommunications industry has established collaborative projects aimed at advancing 6G protocols, with a particular emphasis on IoT integration [4]. Plans for further advancement include a series of workshops across Europe in 2025 [4], demonstrating the continent’s continued leadership in shaping the future of wireless communications.
