This document, D5.3, presents the final implementation and trial results for the four core Use Cases (UCs) in the Culture, Tourism & Entertainment (CTE) domain under the TrialsNet project. Building on progress reported in earlier deliverables D5.1 and D.2, it provides a comprehensive overview of the final implementation steps, the execution of large-scale trials, and the results obtained. The document covers the integration activities and system-level validations carried out during the last phase of the project, as well as the measurement of Key Performance Indicators (KPIs) and Key Value Indicators (KVIs) according to the evaluation methodology previously established. Each UC was deployed and tested in realistic operational environments, including sports venues, airports, cultural heritage sites, and museums, to validate performance and user experience. The trials confirmed the technical feasibility and demonstrated the added value of 5G/B5G (Fifth Generation of mobile communications)/ (Beyond 5G mobile network) technologies for enhancing cultural, tourism, and entertainment services, providing detailed evidence of their impact and benefits.
