The convergence of Non- Terrestrial Networks (NTN) and Satcom on the Move (SOTM) is reshaping global connectivity, enabling resilient communication across terrestrial and satellite domains. As integration with 5G and future 6G accelerates, challenges around spectrum coordination, regulation and cross border operation intensify. SOTM use across land, air and sea adds further complexity, compounded by limited standardised testing and validation. This panel examines regulatory, technical and validation needs, highlighting the importance of harmonised standards to support interoperable, scalable NTN and SOTM deployment.
