In this talk, Dr. Yvonne Weitsch outlines why standardization and regulation are essential for the next generation of satellite- and space-based communications. The presentation walks through the evolution from fragmented proprietary systems toward unified 3GPP-compliant NTN solutions such as IRIS2, and compares different direct-to-cell approaches using mobile satellite or terrestrial mobile spectrum. It also explains the regulatory landscape across ITU, FCC, CEPT, and the EU, including upcoming WRC-27 agenda items that will shape future spectrum allocations.
Additionally, the session highlights challenges like Doppler effects, coexistence with terrestrial networks, and interference management, while showing how testing, monitoring, and compliance tools ensure secure, resilient, mission-critical operations. The result is a clear view of how standards, regulations, and test solutions enable scalable, affordable, and reliable NTN and Future-G communication systems.
