Connecting remote sites: cellular vs satellite vs nothing

Not every site has fibre. We break down the real-world options for getting data out of remote locations in Australia.

The connectivity reality

In an ideal world, every site has reliable, high-bandwidth connectivity. In reality, many Australian operations are:

Hundreds of kilometres from the nearest town

In areas with no fixed-line infrastructure

Dealing with challenging terrain that blocks signals

The question isn't "what's the best connectivity?" It's "what actually works here?"

Option 1: Cellular (4G/5G)

When it works

Cellular coverage in Australia is better than people often assume. The major networks cover most populated areas and many remote regions have 4G coverage along highways and in mining regions.

For sites within cellular range, 4G is often the best option:

Bandwidth: Usually 10-50 Mbps, plenty for most industrial applications

Latency: Low enough for real-time monitoring

Cost: Reasonable monthly data costs

Reliability: Generally stable with proper antenna setup

When it doesn't

Cellular fails when:

You're genuinely out of coverage (check actual coverage maps, not marketing maps)

Your site is in a valley or behind terrain that blocks signal

You need guaranteed uptime and the nearest tower is unreliable

Making it work better

If cellular coverage is marginal:

External antennas make a huge difference. A good directional antenna on a mast can pick up signal that phones can't

Signal boosters can help but have legal limits in Australia

Dual-SIM failover between networks provides redundancy

Option 2: Satellite

Starlink and LEO satellites

Low Earth Orbit (LEO) satellite services like Starlink have changed the game for remote connectivity:

Bandwidth: 50-200 Mbps in good conditions

Latency: 20-40ms (much better than traditional satellite)

Coverage: Works almost anywhere with clear sky view

Cost: Hardware upfront plus monthly subscription

The catch: Starlink needs clear sky view and doesn't work well in heavy rain or with obstructions. It's also still maturing for industrial use.

Traditional satellite (GEO)

Geostationary satellite services are the proven option for truly remote sites:

Bandwidth: Typically 2-10 Mbps

Latency: 500-700ms (too slow for real-time control, fine for monitoring)

Coverage: Works anywhere you can see the sky

Cost: Higher than cellular, equipment and monthly fees

GEO satellite works when nothing else does, but the latency limits what you can do with it.

Option 3: Store and forward

Sometimes the answer is: don't try to maintain a constant connection.

For sites where connectivity is expensive, unreliable, or simply unavailable, store-and-forward approaches work well:

Local data logging: Collect data on-site, store locally

Periodic uploads: Sync when connectivity is available (daily, weekly)

Manual retrieval: Download data during site visits

This works for:

Historical reporting where real-time isn't critical

Remote sites visited regularly for other reasons

Backup when primary connectivity fails

What about nothing?

Before investing in connectivity, ask: what do you actually need the data for?

If the answer is "monthly reporting," maybe quarterly site visits with a USB stick are fine. If it's "real-time alarming," you need reliable connectivity. If it's "we might want it someday," you're spending money without a clear return.

Our recommendation for most sites

For sites with cellular coverage (even marginal):

**Primary:** 4G with external antenna

**Backup:** Different cellular network or Starlink

For genuinely remote sites:

**Primary:** Starlink or LEO satellite

**Backup:** Store-and-forward with local logging

For extremely remote or harsh environments:

**Primary:** GEO satellite

**Backup:** Store-and-forward

The real cost calculation

When comparing options, include:

Equipment (one-time)

Installation (one-time)

Monthly service fees (ongoing)

Data costs (ongoing, often variable)

Maintenance and support (ongoing)

Downtime costs (what does an outage actually cost you?)

Cheap connectivity that's unreliable often costs more than expensive connectivity that works.
