B
Most people use smartphones every day. Traditional mobile phones depend on terrestrial cell towers（地面基站）to send and receive signals. However, cell towers cannot cover every corner of the earth. Deserts, mountains, deep forests and far-away oceans often have no cellular service（移动通信服务）. These places are called "dead zones".
Now, a new technology is changing this. It's a direct connection between satellites and smartphones. It lets common mobile phones link to communication satellites in space. Satellites act like "towers in the sky" to relay signals across the world. This technology can keep people connected anywhere.
One of its key roles is emergency rescue. When hikers or travelers get lost in dead zones, they can send SOS messages and share their positions through satellites. During natural disasters, when ground networks break down, satellite communication still works to save more lives.
The technology also brings wider progress. It supports communication in faraway villages, helps with weather monitoring, and improves ground navigation. At present, the service is mainly for messages and emergency calls. In the future, it may support faster data services and clear voice calls, achieving global coverage.
Some challenges remain to be solved, such as signal speed and battery content. But as technology improves, direct satellite connection will become a common function on smartphones, connecting the world more closely than ever.
