Samsung Validates NR-NTN Modem Performance for LEO Satellite Networks
Case Studies
Samsung Electronics’ System LSI Business needed a way to validate new radio non-terrestrial network modem performance in preparation for satellite-based 5G services. The goal was to evaluate modem behavior under low Earth orbit satellite conditions while supporting end-to-end workflows that reflect future satellite-to-mobile deployment scenarios.
Keysight and Samsung collaborated on a lab-based new radio non-terrestrial network demonstration for Mobile World Congress 2026. The demonstration integrated Keysight’s 5G Network Emulator with a Samsung new radio non-terrestrial network modem to validate satellite and device mobility, service continuity, and higher-throughput Multiple-Input, Multiple-Output configurations.
Keysight NTN Network Emulator Solutions recreate low Earth orbit satellite characteristics in a controlled laboratory environment. This approach gives engineering teams a repeatable way to test modem behavior against representative satellite conditions before commercial services are available at scale.
Samsung and Keysight demonstrated lab-based validation of new radio non-terrestrial network device performance in preparation for satellite-to-mobile deployments. The demonstration focused on conditions aligned with planned low Earth orbit satellite deployments, including Starlink Direct to Cell scenarios.
The collaboration showed how a controlled laboratory workflow can help validate modem performance under representative satellite conditions. This included satellite and device mobility, handover behavior, service continuity, throughput performance, Multiple-Input, Multiple-Output configurations, and positioning emulation.
