VSAT WiFi refers to a WiFi network that uses a Very Small Aperture Terminal (VSAT) for its internet connection, instead of relying on traditional landlines or cellular networks. The VSAT provides the internet connection via satellite, which is then distributed locally through a WiFi router.
Understanding VSAT
A Very Small Aperture Terminal (VSAT) is a data transmission technology. According to the reference material, VSAT is "a data transmission technology used for many types of data management and in high-frequency trading." It transmits data by bouncing signals off satellites. This makes it especially useful in areas where traditional internet infrastructure is unavailable or unreliable. VSAT can be used in place of a large physical network.
How VSAT WiFi Works
-
Satellite Connection: The VSAT terminal uses a satellite dish to transmit and receive data signals from a communication satellite.
-
Internet Access: The satellite acts as a relay, connecting the VSAT terminal to an internet service provider (ISP).
-
WiFi Distribution: A WiFi router is connected to the VSAT terminal. This router broadcasts a wireless signal, allowing devices within range to connect to the internet over WiFi.
Benefits of VSAT WiFi
- Remote Locations: Provides internet access in areas without wired infrastructure.
- Reliability: Can offer a more stable connection than cellular in certain situations.
- Mobility: Suitable for mobile applications where connectivity is needed on the move.
Drawbacks of VSAT WiFi
- Latency: Satellite communication can introduce latency (delay) due to the distance the signal travels.
- Weather Sensitivity: Performance can be affected by adverse weather conditions.
- Cost: VSAT equipment and services can be more expensive than terrestrial internet options.
Example Use Cases
- Maritime: Providing internet access to ships at sea.
- Remote Offices: Connecting offices in rural areas.
- Emergency Response: Establishing communication networks during disasters.
VSAT vs Traditional WiFi
| Feature | VSAT WiFi | Traditional WiFi |
|---|---|---|
| Internet Source | Satellite | Terrestrial (Cable, Fiber, DSL) |
| Location | Remote areas, maritime, mobile applications | Urban and suburban areas with wired infrastructure |
| Latency | Higher | Lower |
| Cost | Generally Higher | Generally Lower |
