Keysight Technologies reported demonstrating a new radio non-terrestrial networks (NR-NTN) connection in band n252 using Samsung Electronics‘ next-generation modem chipset. 

Keysight on Thursday announced the demonstration at CES 2026 including live satellite-to-satellite mobility, calling it an important milestone for the direct-to-cell satellite market. The demonstration validated band n252 in an NTN system. Keysight noted this band is expected adopted by next-generation Low Earth Orbit (LEO) constellations.

Explaining the demonstration, Keysight said it integrates Samsung’s next-generation modem chipset with Keysight’s NTN emulation portfolio “to deliver real, standards-based NTN connectivity across a complete system. The setup validates end-to-end link performance, mobility between satellites, and multi-vendor interoperability, essential requirements for large-scale NTN deployments.” 

“Together with Samsung’s System LSI Business, we are demonstrating the live NTN connection in 3GPP band n252,” commented Peng Cao, vice president and general manager of Keysight’s Wireless Test Group. “The ecosystem is clearly accelerating toward bringing direct-to-cell satellite connectivity to mass-market devices. Keysight’s NTN emulation environment enables chipset and device makers a controlled way to prove multi-satellite mobility, interoperability, and user-level performance, helping the industry move from concept to commercialization.”
