Telecommunications communication
The first and most important application of communication satellites in history is long-distance telephone. Satellite telephone is an essential communication or backup communication equipment for remote islands with limited communication, as well as the edge areas of Antarctica and Greenland, various mountains, seas, and aircraft activities.

Internet connection
Satellite communication technology, as the main means of connecting to broadband Internet, can better serve users in remote areas who are unable to access broadband connections or have high demand for broadband services.

data communication
By providing data transmission from one point to another through satellites, near Earth environmental monitoring equipment such as meteorological stations can use satellites for one-way data transmission or two-way remote monitoring.

Television entertainment
As the mainstream entertainment activity in society, television requires the simultaneous transmission of bandwidth signals to many receivers, and the ability of geostationary communication satellites can more accurately match this demand, thus providing television entertainment services to global users more conveniently.

Satellite broadcasting
Satellite broadcasting provides audio broadcasting services in some countries, allowing listeners to listen to the same audio programs from anywhere, covering a much wider geographical range than terrestrial radio signals.
