5G solutions for verticals is a well-defined European objective. This requires developing 5G infrastructures to address a wide range of applications adopting flexible architectures, offering converged services across heterogeneous technology domains with unified software control. However, vertical industries today can only verify use cases in small scales in commercial environments, before investing in large scale deployments. Through ICT-17 projects 5G infrastructures become available to verticals to test their applications, however large-scale trials are still not possible. 5G-VICTORI will conduct large scale trials for advanced vertical use case verification focusing on Transportation, Energy, Media and Factories of the Future and cross-vertical use cases. It leverages 5G network technologies developed in 5G-PPP Phase-1 and Phase-2 projects 5G-XHaul and 5G-PICTURE and exploits extensively existing facilities interconnecting main sites of all ICT-17 infrastructures i.e. 5G-VINNI, 5GENESIS and 5G-EVE and the 5G UK test-bed in a Pan-European Infrastructure. The project will provide enhancements of existing infrastructures towards integration of a large variety of vertical and cross-vertical use cases. 5G-VICTORI’s platform aims to transform current closed, purposely developed and dedicated infrastructures into open environments where resources and functions are exposed to ICT and vertical industries through common vertical and non-vertical specific repositories. These functions can be accessed shared on demand and deployed to compose very diverse set of services in a large variety of ecosystems. 5G-VICTORI’s uniquely strong consortium brings together major players form ICT including operators, equipment vendors academic and research organisation and SMEs as well as main players from vertical industries including nationwide rail and electricity operators, rail technology vendors, media content delivery players and a number of SMEs focusing on advanced vertical services.
