VSAT, Starlink or fibre? Choosing connectivity for remote operations

Getting a reliable internet connection to a mine, a clinic or a county field office is rarely a matter of calling an ISP. What works depends on where the site is, what staff run over the link, and how much downtime the operation can absorb.

The three options that work in practice

Fibre / terrestrial broadband

Where fibre exists, it is usually the best value: fast, low latency and plenty of data. Coverage is the problem. Outside the main urban corridors it is not there, and where it is, one cable cut can take a site offline for hours or days. Use it as the main link in the city, but not as the only link at a remote site.

VSAT (geostationary satellite)

VSAT works anywhere you can see the sky, which is why it has connected remote sites across the region for years. The technology is mature, holds up in bad weather if the link is designed properly, and is backed by established carriers. You pay for that with higher latency (the signal goes to a satellite about 36,000 km up and back) and a higher cost per megabit than fibre. It suits remote sites, as main link or backup, where staying up matters more than raw speed.

LEO satellite (e.g. Starlink)

Low-earth-orbit services have much lower latency and higher speeds than traditional VSAT, and a kit can be up and running quickly. For many remote sites they have changed the calculation. Before relying on one, check local licensing and availability, how it performs in heavy rain, and whether the support and contention terms are good enough for systems you cannot afford to lose. We usually pair LEO with another link rather than use it on its own.

For critical sites, use two links

If the site cannot go offline, plan for two links with automatic failover. A setup we install often is a main link (fibre or LEO) with a VSAT or LEO backup, and a router that switches over as soon as the main link drops, so most staff never notice. Add bandwidth management so that the important applications keep priority while the site is running on the backup.

Questions to ask before you choose

  • Which applications must stay online, and how much latency can they handle?
  • How many hours of downtime a month would actually hurt the operation?
  • Is the site permanent or temporary, and how soon must it be online?
  • What is available and licensed at that exact location today?
  • Who installs, monitors and fixes it when it breaks at 2am?

The last question is the one most people skip. A link is only as reliable as the people who look after it.
