Samsung Electronics and Keysight have announced a pivotal demonstration for the upcoming MWC 2026. They will showcase a test that combines Samsung's next-generation NR-NTN modem with Keysight's satellite emulation technology, precisely recreating the operational parameters of Starlink's 'Direct to Cell' service.
This isn't just another tech demo; it's a critical step toward making satellite-to-phone communication a mainstream reality. The significance lies in three key areas. First, on the standards front, the technology is rapidly maturing. Following the initial standards set by 3GPP Release 17, the successful live test of the new n252 band (Release 19) at CES 2026 proved that multi-band connectivity is viable. This reduces the risk for device makers, ensuring their products can seamlessly switch between different satellite frequencies.
Second, the regulatory path is clear. In 2024, the U.S. Federal Communications Commission (FCC) established its SCS framework and subsequently approved a license for T-Mobile and SpaceX. This means there's a direct route from successful tests like this one to actual commercial service deployment, removing major uncertainties for businesses.
Third, there is immense market demand. Billions of people globally still lack reliable mobile broadband. Direct-to-cell technology is perfectly suited to bridge these coverage gaps cost-effectively. Its utility has also been proven in public safety scenarios, such as providing temporary connectivity after natural disasters. This combination of commercial opportunity and social benefit creates a powerful incentive for the entire ecosystem.
The recent market activity confirms this narrative. Following the announcements of the successful CES test and the upcoming MWC demo, both Keysight's and Samsung's stock prices saw significant jumps. This signals that investors are gaining confidence that the era of testing is transitioning into an era of commercialization for the entire value chain, from testing equipment and chips to the final devices in our hands.
- NTN (Non-Terrestrial Networks): Communication networks that use satellites or other airborne platforms instead of ground-based towers.
- SCS (Supplemental Coverage from Space): A regulatory framework that allows satellite operators to partner with mobile carriers to fill in coverage gaps in terrestrial networks.
- LEO (Low Earth Orbit): An orbit relatively close to Earth's surface (under 2,000 km). Satellites in LEO can provide faster communication with less delay compared to those in higher orbits.
