🌐 Very Small Aperture Terminal (VSAT): A Gateway to Remote Connectivity

Why Satellite Internet Is Important

Many remote areas have no wired internet. That’s where VSAT helps. A Very Small Aperture Terminal (VSAT) is a system that uses small antennas to send and receive data through satellites. It works where normal internet cannot reach.

How VSAT Works Step by Step

A basic VSAT setup includes:

  • A small dish antenna

  • An outdoor unit (ODU) that talks to the satellite

  • A central hub connected to the internet

Because of this setup, users in remote areas can connect without cables. This makes VSAT great for deserts, mountains, or oceans.

Where VSAT Is Most Useful

VSAT is used in many fields. Some examples include:

  • 🏦 Banks in villages for ATMs and branches

  • 🛢️ Oil rigs in the middle of the sea

  • 🛒 Shops in remote towns

  • ✈️ Planes and ships for communication

  • 🛡️ Defense and emergency teams in the field

As you can see, VSAT is not just about internet—it supports vital services too.

VSAT vs. Starlink: Which One Suits You?

Feature VSAT (GEO Orbit) Starlink (LEO Orbit)
Satellite Height ~36,000 km ~550–1,200 km
Main Users Companies, NGOs Homes, small businesses
Installation Done by experts Do-it-yourself kit
Delay (Latency) 500–700 ms 20–50 ms
Price Higher Medium

So, Starlink is better for home use. VSAT is ideal for business and security use.
