Satellite calling, i.e. communication via satellite, has a variety of uses and advantages, especially in certain occasions and environments. Here are some of the main uses of satellite calling:
Communication in distant areasFor remote areas of the earth or areas that are difficult to be covered by traditional communication networks (such as deep mountains, oceans, polar regions, etc.), satellite calls provide a reliable means of communication, enabling people in these areas to stay in touch with the outside world.
Emergency response and disaster recovery: Terrestrial communications infrastructure can be disrupted after a natural disaster (e.g., hurricane, flood) or man-made disaster. Satellite calls can quickly restore communications in these situations, providing critical support for relief operations and recovery.
International and maritime communicationsSatellite calls enable ships, aircraft, and multinational companies to communicate efficiently across the globe, ensuring operational continuity and security.
Military and DefenseIn military operations, satellite calls provide instant communication capabilities across national borders, which are essential for command and control, reconnaissance and surveillance, remote operations, and more.
Research and exploration: Scientific research teams that rely on satellite calls for data transmission and communication with the outside world when working in extreme environments (e.g., Antarctica, deep-sea exploration).
Mobile communicationsFor people who travel a lot or move between multiple regions, satellite** provides a solution to communicate no matter where they are.
The advantages of satellite calling lie in its wide coverage, high reliability, and ability to communicate in special environments. However, there are some limitations to satellite communications, such as higher costs, possible signal delays (due to the need for signals to travel back and forth between Earth and satellites), and the need for specific equipment. Despite this, satellite calls remain an irreplaceable means of communication in many fields and situations.
