"Keysight Technologies and KT SAT have revealed a live multi-orbit proof-of-concept demonstration, showcasing session continuity from a geostationary Earth orbit (GEO) to an emulated low Earth orbit (LEO) link, thereby validating a core advanced communications capability. Explaining the rationale for their move, the companies said that as the industry moves towards 6G, integrating satellite and terrestrial networks is essential to deliver continuous coverage and resilient service in remote or disaster-affected areas."
"By incorporating Ku‑band operation into this multi-orbit mobility scenario, Keysight and KT SAT believe they have validated NTN behaviours in a frequency range now central to emerging global standards and operator deployment strategies. And by moving beyond earlier demonstrations focused on single-orbit GEO connectivity, the organisations said they have shown how operators can evolve from point-to-point satellite links to continuous multi-orbit mobility,"
Keysight Technologies and KT SAT executed a live multi-orbit proof-of-concept demonstrating session continuity from a geostationary Earth orbit (GEO) to an emulated low Earth orbit (LEO) link. The demonstration targeted integration of satellite and terrestrial networks for continuous coverage and resilient service as networks migrate toward 6G. The trial addressed engineering challenges such as long delays, Doppler effects and unstable links. The setup enabled controlled laboratory evaluation of real non-terrestrial network (NTN) behaviour before large constellations deployment. The demonstration used Ku‑band operation and KOREASAT-6A at KT SAT's Kumsan network operation centre, showing the industry's first NR-NTN multi-orbit handover and validating 3GPP Rel‑19 Ku‑band parameters.
