Which technology is used for satellite communications in industrial applications?

In industrial applications, VSAT (Very Small Aperture Terminal) technology is utilized for satellite communications because it enables reliable and continuous data transmission over wide geographic areas. VSAT systems operate by using a satellite to facilitate communication between remote locations and centralized operations. This is particularly valuable in industries where operational sites may be located in remote or unconnected areas where traditional terrestrial communication infrastructure is not viable.

The capability of VSAT to provide high-speed internet access and support various services such as voice, video, and data makes it an essential solution for industries like oil and gas, mining, and agriculture, where constant communication is crucial for monitoring and control. Additionally, VSAT systems can be deployed relatively quickly and are designed to withstand harsh environmental conditions commonly found at industrial sites.

Other technologies listed, such as WiFi, Bluetooth, and mesh networking, serve different purposes and are typically limited to shorter ranges and specific environments. WiFi is primarily used for local area networking, Bluetooth for short-range personal area networking, and mesh networking works well for creating resilient and extensible local networks but is not suited for the wide coverage provided by VSAT in satellite communications. Therefore, in the context of satellite communications in industrial applications, VSAT is the most appropriate and effective choice.
