MediaTek is doubling down on its satellite ambitions. The chipmaker has announced a new collaboration with Starlink aimed at expanding access to satellite-powered wireless emergency alerts worldwide — a move that could significantly reshape how smartphones stay connected during disasters.
The partnership focuses on delivering emergency alert messages via satellite communication, ensuring users can receive critical notifications even when traditional cellular networks fail. By integrating with Starlink’s growing satellite constellation, MediaTek-powered devices will support alerts from major public safety systems, including the Commercial Mobile Alert System (CMAS), the Wireless Emergency Alerts (WEA) framework, and the Earthquake and Tsunami Warning System (ETWS).
In practical terms, this means more people will be able to receive life-saving alerts during hurricanes, wildfires, earthquakes, tsunamis, and other potentially catastrophic events — even in areas with little to no terrestrial cellular coverage.
Live Demo at MWC 2026
At Mobile World Congress 2026, MediaTek is showcasing Starlink Mobile service running on a device powered by the MediaTek M90 — the world’s first 5G modem to integrate satellite connectivity directly into the chipset.
The demonstration highlights “Direct to Cell” capability using the S-Band spectrum. Unlike traditional satellite phones that require specialised hardware, this approach enables standard smartphones to connect directly to satellites for emergency messaging. The goal is simple: allow users to receive urgent alerts anywhere on the planet without relying solely on ground-based towers.
Real-World Deployment Already Underway
This isn’t just a proof of concept. The collaboration has already enabled Wireless Emergency Alerts (WEA) in the United States, Canada, and Japan. According to MediaTek, more than 4.4 million people have connected to Starlink Mobile during emergencies, demonstrating real-world demand and functionality.
That milestone is significant. During large-scale natural disasters, cellular infrastructure is often among the first systems to go offline due to power outages or physical damage. Satellite-based alerting provides a resilient fallback layer — one that doesn’t depend on local infrastructure remaining intact.
Closing the Coverage Gap
JC Hsu, Corporate Senior Vice President at MediaTek and General Manager of its Wireless Communications Business Unit, emphasized that the partnership represents more than just a feature upgrade.
By combining MediaTek’s modem technology with Starlink’s satellite network, the companies aim to fundamentally close the coverage gaps that emerge during disasters. The solution leverages standardised 5G NR-NTN (New Radio Non-Terrestrial Network) technology, marking a major step toward commercial deployment of satellite-integrated cellular services.
In other words, this isn’t proprietary stopgap tech — it’s built on emerging global standards designed to integrate satellite networks into mainstream 5G infrastructure.
The Bigger Picture
Satellite connectivity is rapidly becoming the next competitive battleground in mobile technology. What began as limited emergency texting features is evolving into a broader vision of hybrid terrestrial-satellite networks.
For MediaTek, this move positions the company at the forefront of modem-level satellite integration. For Starlink, it expands the utility of its constellation beyond broadband and into mass-market mobile safety infrastructure.
If successful at scale, the collaboration could redefine expectations around mobile reliability. Instead of asking whether your phone has a signal, the question may soon be whether it can connect to space.
And in emergency scenarios, that difference could be life-saving.
