This document is a second cycle deliverable that follows up on the UC scenario definition, requirements, and architecture design performed in D2.1. Its primary objective is to conduct a comprehensive analysis and detailed definition of the requirements and designs necessary to enable the execution of large-scale use cases on the FIDAL fabric. By leveraging and building upon previous and ongoing work from EU-funded 5G-PPP and SNS projects, this document aims to establish a solid framework for the successful deployment of FIDAL's 5G labs and facilities.
