Keysight and KT SAT complete industry‑first 5G NR‑NTN multi‑orbit handover between GEO KOREASAT‑6A and LEO

Keysight Technologies and KT SAT completed the industry's first successful 5G NR‑NTN multi‑orbit handover, transitioning a live connection between commercial GEO KOREASAT‑6A and a LEO satellite. The demonstration validates NR non‑terrestrial network interoperability and handover procedures across distinct orbital regimes.

Briefing

What Hype is tracking

Confirms practical NR‑NTN handover between GEO and LEO, a technical prerequisite for continuous multi‑orbit connectivity and seamless service continuity across orbital layers.
Reinforces progress toward multi‑orbit 5G systems alongside efforts to develop virtual, multi‑orbit 5G modems (see work on a virtual 5G satellite modem for multi‑orbit).
Complements recent in‑orbit 5G and high‑frequency demonstrations — from narrowband LEO IoT tests to mmWave experiments — signaling a shift from single‑orbit proofs to interoperable operational networks (first 3GPP Release 17 narrowband LEO‑to‑IoT connection, first in‑orbit 75 GHz mmWave signal).
