5G is being deployed and B5G connectivity is under study and standardization. Benefits brought by the 5G/B5G air interface are numerous and 5G is more than just an evolution of radio technology since it consists of innovative concepts: the application of network softwarization and programmability paradigms to the overall network design, the reduced latency promised by edge computing, or the concept of network slicing. These innovations open the door to new vertical-specific services, even capable of saving more lives. The paper describes four use cases to demonstrate the large-scale trialing of the B5G technology specifically devoted to eHealth and Emergency domains, by supporting the B5G applications in large-scale environments (e.g., hospitals) and bringing novel applications (e.g., Remote Proctoring and Smart Ambulance) and on societal benefits in eHealth and Emergency areas through the development of innovative B5G/6G applications. The work is a part of a more complete behavior, TrialsNet project, within SNS JU European Commission Programme, considering other field of application of B5G connectivity.
