MediaTek announced that it is collaborating with Starlink to support wireless emergency alert messages via satellite communication. Through this joint effort, more mobile users worldwide will be able to receive alerts from the Commercial Mobile Alert System (CMAS), Wireless Emergency Alerts (WEA) framework, and the Earthquake and Tsunami Warning System (ETWS), providing critical communications during natural disasters or other potential life-threatening situations.
At Mobile World Congress 2026, MediaTek demonstrated the Starlink Mobile service on a device powered by the MediaTek M90, the world’s first 5G modem with integrated satellite technology. Direct to Cell utilizes the S-Band to ensure consumers can use their mobile devices to be informed of emergencies in a timely manner, anywhere in the world.
The collaboration has already enabled WEA services in the United States, Canada and Japan, and more than 4.4 million people have connected to Starlink Mobile during emergencies.
“This leverages our leadership in satellite technology and combines it with Starlink’s satellite network to ensure that more people have access to life-saving alerts in critical situations,” said JC Hsu, corporate senior vice president at MediaTek and general manager of the Wireless Communications Business Unit. “Our solution fundamentally solves the cellular coverage gaps that often occur during natural disasters and other emergencies and is an important step for commercial deployment of standardized NR-NTN technology.”
