X-TREME 6G proposal relies on a unique industry led consortium to provide a foundational open microelectronics platform in Europe with the objective to create and design key disruptive next generation chiplets and chipsets for 6G use cases. The idea is to break-up the full potential of best-in-class Silicon BiCMOS, InP and heterogeneous 3D integration for high capacity radio access technologies such as wireless back-hauling at sub-TeraHertz frequencies, Joint Communication And Sensing, Non Terrestrial Networks and Network as a Sensor. New classes of chipsets will unleash the full potential of 6G and enable the emergence of new applications through specific developments for the underpinning novel microelectronic technologies. X-TREME 6G valorizes also resource efficient 6G algorithms and an ML/AI software toolbox for computationally efficient silicon-ready baseband extensions. Part of the SNS “Microelectronic Lighthouse” visionary initiative, the proposal’s ambition is to establish and maintain a sustainable open platform for the duration of the SNS program and beyond, to support 6G verticals. By nurturing the links with the emerging Chips JU pilot lines, the platform acts as a first fabric to accelerate joint initiatives between SNS and Chips JUs. In a nutshell, X-TREME 6G will provide tangible contributions towards an experimentation EU framework for 6G, demonstrating the full benefit of the newly developed chipsets and chiplets for a set of emerging 6G high potential use cases (wireless back-hauling, JCAS, NTN, NaS); while being open to dynamically support the emerging 6G ecosystem (SMEs, Industries, Service Providers, Government etc.) and evaluate additional 6G challenges and expectations. By strengthening and extending the 6G functionality and microelectronics supply chain, X-TREME 6G contributes towards a network-centric democratized and open 6G ecosystem able to release the current hyperscaler’s market embrace, while empowers European Industry at large.

SUSTAIN-6G will develop a holistic sustainability framework in the context of 6G, addressing all three sustainability areas (environmental, societal, economic), and factors impacting sustainable 6G technology and 6G technology for improving verticals’ sustainability. The framework will be applied to key vertical sectors, in an end-to-end manner, considering the full lifecycle of assets. SUSTAIN-6G will identify the cross-points between what sustainability needs are, which challenges 6G and verticals need to consider, what 6G should do to address these challenges, and how society and economy benefit from responsible innovation. To achieve this, the project will provide a driving force for multiple activities and a hub, to integrate research and innovation from previous and ongoing projects, develop innovative concepts and solutions, and address gaps and trade-offs in technology, processes and methodologies. The concepts and solutions will be validated and evaluated by proof-of-concepts on their sustainability impact and performance. The insights from these PoCs, and the proven processes and methodologies will be consolidated into guidelines, best practices and roadmaps to drive the full integration of sustainability aspects into future communication and vertical systems, in close collaboration with stakeholders and other SNS projects, and for use across the EU and beyond. The outputs and impact of SUSTAIN-6G will provide the foundation for industry-wide standardisation that will enhance existing ecosystems, help to shape a sustainable future that develops and thrives within planetary boundaries, and strives to protect and restore the environment, while respecting EU values and rules. Recognising the complexity and multifaceted characteristics of sustainability, SUSTAIN-6G will achieve these objectives through its multidisciplinary consortium, composed of 6G and vertical technology, social science, and economic experts, and with relevant external stakeholders.

Three place-based innovation ecosystems in Cyprus, Greece and Bulgaria partner together to create an Excellence Hub for Future Cities and Regions in Southeast Europe (SEE). The METACITIES Excellence Hub is a sustainable network that offers a common platform for collaboration, cross-fertilization, and best practices sharing across borders, sectors and disciplines on knowledge production, circulation and use. Founded upon a joint R&I strategy, a nexus of collaborative links across sectors, joint research, innovation and outreach activities as well as business modelling and sustainability plans, the collaboration aims to benefit citizens, stakeholders, regional ecosystems and the whole SEE region. The thematic focus on future and metaverse cities necessitates the definition of ambitious R&I agendas and the uptake of advanced digital technologies. Digital Twins (DT) of future cities/regions provide accurate and reliable reference representation seamlessly unifying the physical, digital and human worlds and enabling stakeholders to assess the effects of any changes before investments and implementations actually occur. The proposed Open Digital Twin Framework facilitates co-development of complementary future city domains along with their equivalent DTs. The applied Quadruple Helix Model forges synergies among actors and alignment of public and private sector priorities for regional development. PoC studies, small-scale pilots and feasibility assessments validate project outcomes. Green Business and Operation Models will be developed for future and metaverse cities, as well as for the METACITIES Excellence Hub. Investment and Sustainability Plans will mobilize the communities of the three innovation ecosystems to progress faster in joined efforts. Common investment plans for R&I, infrastructures and support for real-life experimentation, aim to leverage national, regional and European funds as well as crowd funds and private capital in a synergetic manner.

Long-term towards Evolved 5G and 6G research needs mobilization of massive volumes of ideas, from which the best can emerge and be taken into standardization. It is the convergence of the cyber and physical worlds that could be achieved with the very low latency and high data capacity of Beyond 5G and 6G networks and thus the creation of services such as digital twins and internet of senses/haptic applications. This future eco-system is on course to be more collaborative and inclusive than previous generations of network, and FIDAL aims to lead the way by promoting open architectures, large experimentation sites and taking a multi-stakeholder approach. FIDAL steps in, targeting the augmentation of human capabilities, allowing Media & PPDR vertical industry players to perform advanced technological and business validation in large-scale field trials of highly innovative and advanced applications, that exploit Evolved 5G technologies. This, in turn, will provide extensive and valuable feedback to the broader industry, academia, innovators and community before wide commercial deployments of Evolved 5G networks throughout Europe. FIDAL key objective is to extend and deliver (i) advanced future proof Evolved 5G test infrastructures, anticipating evolution into next SNS phase, (ii) open & accessible to support 3rd party vertical experiments, (iii) test environments for rapid prototyping and large-scale validation of advanced, forward-looking applications. The project will build on the success of 5G-PPP Phase 3 projects, producing a unified experimentation framework with Zero-Touch orchestration, reusable Network Applications and secure AI as a Service capabilities. FIDAL will deploy 3 testbeds and 3 large-scale test infrastructures in Greece, Norway and Spain aiming to validate Evolved 5G technologies in a user context to maximise downstream take up, thus cultivating the ground for 6G.
