Vad är satellitkommunikation?
Satellite communication is the wireless transmission of data via satellites in orbit. It is used where traditional infrastructure is unavailable or insufficient.
How does it work?
Data is transmitted between a ground station, a satellite, and the receiving device.
Types of Satellites:
- GEO (Geostationary Earth Orbit): Stable coverage, high latency
- MEO (Medium Earth Orbit): Commonly used for GPS and navigation
- LEO (Low Earth Orbit): Lower latency, suitable for broadband (e.g., Starlink)
Benefits of Satellite Communication:
- Global coverage
- Independent infrastructure
- Reliable during crises
Challenges:
- Latency (delays in communication)
- High cost
- Weather-dependent performance
Use Cases:
- Crisis preparedness
- Maritime and aviation industries
- Industry in remote locations
- Events without existing connectivity
