Humanity envisions the future world with cars driving themselves, the holograms in video conferences, augmented reality used everywhere to assist our daily life, and the list continues. The previous generation of mobile networks could not support such applications, and so the redesign of the network was decided with the 5th generation (5G) network standardization. In the redesigned network topology the signal processing previously occurred on the antenna site was moved to a central location and virtualized. This disaggregation allowed advanced functionalities and reduce the cost of antenna sites. On the other hand, it generated the need for a very fast and low latency connection between these disaggregated units (fronthaul) which cannot be supported with current wireless technologies and so only the fiber can be used. The MIMOSA aims to combine concepts from the RF world with integrated photonics for producing and demonstrating a compact electronically reconfigurable optical MIMO radiating system. The multibeam feeding network and the radiating elements, antennas, will be designed as a single monolithic photonic chip, which will reduce significantly the cost and form factor of the system. A system with at least 8 controllable beams will be designed. With the researcher’s background lying in the field of RF and wireless communications, his close collaboration with a host institute with strong expertise in the field of photonics provides the optimal framework for translating wireless needs into optically-enabled realities. Such a multibeam steerable MIMO system is expected to offer high availability links operating in real-life atmospheric conditions offering capacities higher than 50Gbps for up to 1000m link distance. The project will generate a framework for the implementation of high data rate optical wireless links capable to support 5G and beyond fronthaul requirements while reducing the cost, mass, form factor, and power consumption of the links.

The exponential demand on global wireless data streaming services is pushing current communication network technologies to their limits. To respond to this demand, future 6G networks will depend on Tbit/sec data rate transmission via easily deployable and energy-efficient wireless links. Current 5G wireless systems, characterized by their small spectral bandwidths and high power electronics are fundamentally limited in terms of achievable data rates vs energy consumption. TeraGreen develops a new disruptive technology path for sustainable and scalable commercial exploitation of the THz spectrum for energy-efficient and Tbit/sec wireless communication links enabled by a unique combination of: • Quasi-optical MIMO antennas where a record number of wide-band data signals are being transmitted in parallel through a point-to-point wireless link with an unpresented low level of radiated energy. • Low-energy consumption and record wideband THz transmitters and receivers, in one of the most advanced silicon process in the world with great commercialization potential. • A novel baseband with zero-crossing modulation enabling energy-efficient wideband communication using 1-bit A/D conversion with temporal oversampling. TeraGreen is expected to reduce the power consumption in future 6G base stations by a factor of at least 1000 in terms of energy per bit, while increasing the aggregated data rates by a factor of at least 10. TeraGreen will perform several wireless link demonstrations to showcase its commercial use for wireless backhaul and fixed wireless access. The partners of TeraGreen form a unique European value chain of scientific and technology leadership in their respective fields. The success of TeraGreen will help Europe to be on the foremost frontier in the evolution of mobile networks towards 6G and beyond.

Cloud environments are notorious for their lack of stability in performance characteristics, a feature that makes it extremely difficult for owners of time-critical applications to make the decisive step for migration and owners of SaaS to be unable to present performance vs cost tradeoffs to their customers when acting as IaaS customers. CLOUDPERFECT aims at delivering a set of tools and processes that will enable a) Cloud providers to enhance the stability and performance effectiveness of their infrastructures, through modelling/understanding of the overheads, optimal groupings of concurrently running services, runtime analysis and adaptation, thus gaining a competitive advantage b) Cloud adopters to understand the computational nature of their applications, investigate abstracted and understandable QoS metrics for providers ranking, minimize the time of procurement and provider selection processes, automate deployment and orchestration processes, balance their selection between cost and performance to optimize their competitiveness, define according SLA levels (if on the SaaS level) and monitor the maintenance of their SLA c) 3rd parties to act as independent validators of Cloud QoS features, through a constant monitoring, benchmarking and evaluation process, filling a gap in the current brokerage/consultancy domain for performance evaluation and SLA auditing. The innovation action starts from mature existing prototypes derived from previous EC funded projects and aims at extending their TRL levels in order to support a spin-off entity to be created for the role of QoE Assessment Broker and Toolkit Consultant. The project will cover extensive experimentation with relation to the applicability of the envisioned toolkits in 4 facilities, while focusing on two heavy-weight industrial cases such as CFD and ERP/CRM, for which the overall value chain has been represented in the consortium, targeting domains such as manufacturing and telecom.
