Within the reported period of the project, 5G-COMPLETE project achieved significant breakthroughs in enhancing network functionality and capacity at the edge. The project focused on several key areas, resulting in the development of cutting-edge technologies and solutions. One major accomplishment was the creation of an SDN-compatible mmWave (PtMP) mesh node operating at 60 GHz with a 360-degree coverage. This mesh node, embedded into a device, delivered a capacity of up to 10 Gbps to client nodes with high energy efficiency. It fully supported self-organizing network functionality, enabling spectrum sharing and optimizing usage. Additionally, a fully integrated THz transceiver for the D-band was developed, providing a wireless capacity of up to 25 Gbps with remarkable energy efficiency. To address 5G fronthaul-midhaul and backhaul requirements, the project implemented a time and bandwidth elastic optical transport network. This network interconnected Remote Radio Heads with compute and storage resources, supporting both digital and analog fronthaul, midhaul, and backhaul services. In the realm of DSP platforms, 5G-COMPLETE developed innovative solutions for 25 Gbaud PAM-4 digital transport, achieving significant bandwidth efficiency gains. The DSP engine designed for V-band radio at 57-64 GHz was integrated into a modular baseband processor capable of supporting ultra-broadband operation within the D-band, showcasing record analog Fiber-Wireless transport rates. Security challenges in multi-tenancy and remote/edge environments were addressed through the integration of a comprehensive security toolbox. This toolbox included hardware- and software-based security functions, ensuring end-to-end security for critical workloads. The project tackled the complexity of resource allocation in multi-technology environments, leveraging optimization theory and AI/ML techniques. Solutions were developed for optimal network deployment and operation, addressing challenges in network, computational, and storage resource allocation. In the domain of edge computing, 5G-COMPLETE provided solutions for multi-tenancy, low-latency communication, and near-instant application spawn and tear-down times. The project delivered a secure, lightweight, and efficient framework, enabling serverless computing paradigms at the edge. A key contribution was the development of an end-to-end 5G network slicing management and orchestration framework. This framework dynamically reconfigured multi-technology networks at service runtime, incorporating efficient slice sharing strategies and service orchestration mechanisms. The architecture of the 5G network designed by 5G-COMPLETE capitalized on recent advances in Ethernet-based fronthaul standardization. The project achieved converged digital and analog transmission, a converged analog Fiber-Wireless fronthaul/midhaul/backhaul platform, and intelligent centralized management for high energy efficiency. Validation of the developed technologies was conducted through a series of scalable lab- and field-trial demonstrators, ensuring the practical applicability of the innovations. The project concluded with the formulation of a holistic roadmap and business plan for the seamless migration of 5G-COMPLETE technologies into 5G networks, identifying various business opportunities for the stakeholders involved.
