We are at the “eve” of a fundamental transition in 5G, and the aspiration of 5G-EVE is to create the foundations for a pervasive roll-out of end-to-end 5G networks in Europe. 5G-EVE supports this fundamental transition by offering to vertical industries and to all 5GPPP Phase3 projects facilities to validate their network KPIs and their services. Important representatives of these vertical industries are directly involved as partners of 5G-EVE exactly to influence the design of the end-to-end 5G services, and to provide an early assessment. The 5G-EVE end-to-end facility consists of the interconnection of four 5G-site-facilities (France, Spain, Italy, Greece), which have been selected because of their considerable previous work with vertical industries and standardisation bodies, on top of their 5G technology competences. 5G-EVE aims at creating synergies between a significant number of facilities that will ensure sustainability and impact in terms of exploitation. The 5G-EVE facility will enable experiments with: (a) heterogeneous access, including NR, licensed/unlicensed spectrum, advanced spectrum management; (b) Mobile Edge Computing, backhaul, core/service technologies; (c) means for site-interworking and multi-site/domain/technology slicing/orchestration. 5G-EVE will be initially compliant with 3GPP Rel. 15 and, later on, with Rel. 16. Industrial verticals will be facilitated in the specification/analysis of experiments through: (a) intent-based, and other high-level, interfaces; (b) means for advanced 5G testing, i.e., for KPI analysis, technology benchmarking, performance diagnosis. A VNF pool, including open source and proprietary, radio/network/service, components will be developed and made available. 5G-EVE will impact standards, and has the potential and strategy for ensuring the sustainability of the facility beyond the project lifetime, therefore becoming a cornerstone of the 5G PPP programme and beyond.
