AMAZING-6G proposes a novel set of 14 use cases in the domains of Healthcare, Public Safety, Energy and Transport (including Rail) which will be showcased in large-scale trials and pilots across Europe. Innovative technology enablers are planned to be developed and tested in the areas of Communications, Compute-as-a-Service, Applications and AI, IoT and localization. Security aspects will be taken into consideration in the development of solutions. Framed in this context, the significance of large-scale trials in B5G/6G networks lies not only in their ability to validate the technical capabilities of the technology but also in their capacity to unveil new use cases and applications that were previously inconceivable. As we move towards a world where the Internet of Things (IoT), augmented reality, and artificial intelligence play central roles in our daily lives, these trials provide a unique opportunity to explore the potential of B5G/6G in fostering innovative solutions across various sectors, from healthcare and transportation to utilities and public/environment safety. Through large-scale trials, stakeholders can gain valuable insights into the transformative power of B5G/6G networks and strategically position themselves to harness the full spectrum of opportunities that this cutting-edge technology offers.
