Cellular vs. Satellite for Remote Water Monitoring
For most farm and ranch water monitoring, low-power cellular is the better choice — and the default is NB-IoT, a cellular standard built for sensors that draws very little power, costs the least to run, and works wherever there's rural coverage. Standard LTE is available where you need it, at a higher cost. Low-orbit satellite is the option for truly off-grid sites with no cell signal at all: it reaches almost anywhere, but it costs more and tends to be less consistent. The right answer comes down to coverage at your specific watering points.
Three ways to get a reading off a remote tank
Every option does the same job — move a level reading from a remote tank to your phone — but they take different roads, with different costs and trade-offs.
- NB-IoT (the default). A narrowband, low-power cellular standard purpose-built for sensors. The device has a SIM and talks to the nearest cell tower, sending small packets of data with very little power. It’s the most economical to run and the easiest on the battery, which is why it’s Meterra’s standard.
- LTE (where it fits better). The same cellular networks your phone uses, carrying more data and often reaching more places. It costs more and draws more power than NB-IoT, so it’s used where it’s the right fit for a site rather than as the default.
- Low-orbit satellite (for true dead zones). The sensor sends its reading up to a passing satellite instead of a tower. It doesn’t need any ground infrastructure nearby, so it works almost anywhere with a clear view of the sky — at a higher cost, and with less consistency.
Cost and power
This is where NB-IoT pulls ahead for everyday use, and where satellite carries a premium:
- Hardware and subscription. NB-IoT devices and plans are the least expensive, up front and monthly. LTE costs more. Satellite costs the most, for the reach it provides.
- Power draw. NB-IoT is engineered for ultra-low power, which is what lets a sensor run for years on a battery. LTE uses more; satellite transmission generally takes the most energy per message.
- Reporting frequency. Lower cost and power let cellular report on a comfortable schedule; satellite plans often meter messages more tightly to control cost.
Coverage and reliability
The real question is “what’s available at this exact spot?” — and the honest trade-off runs in both directions:
- Cellular is consistent where it reaches. NB-IoT in particular reaches further and pushes through obstacles better than voice or smartphone data, so a watering point that drops your phone call may still carry sensor traffic just fine.
- Satellite reaches places cellular can’t, but it can be less reliable: a low-orbit network depends on a satellite being overhead when the sensor reports, and coverage consistency varies. It solves “no signal at all” — it isn’t automatically the more dependable choice.
That’s why a real coverage check at the actual location beats assuming a spot is a dead zone — or assuming satellite is a free upgrade.
How to choose
- List your watering points and roughly where each one sits.
- Check coverage at those points — not the ranch headquarters, the actual tanks and dams.
- Use NB-IoT wherever it reaches, which on most operations is nearly everywhere.
- Step up to LTE where it’s the better fit for a particular site.
- Reserve satellite for the genuine dead zones with no carrier signal at all.
Meterra runs on Verizon NB-IoT cellular by default, with LTE and satellite available where a site needs them.

Frequently asked questions
Is cellular or satellite better for remote water monitoring?
Cellular is better for most operations — lower cost, lower power, and reliable wherever there's rural coverage. The default is NB-IoT, a low-power cellular standard built for sensors; standard LTE is available where it's needed at a higher cost. Satellite is the right call only where there's no cell signal at all. The deciding factor is coverage at your actual watering points, not a blanket rule.
What's the difference between NB-IoT and LTE?
Both are cellular. NB-IoT is a narrowband, ultra-low-power standard purpose-built for sensors that send small amounts of data — it's the most economical and battery-friendly, and it's Meterra's default. Standard LTE carries more data and is more widely available, but it costs more to run and uses more power, so it's used where it's the better fit for a site.
Will cellular work on the back of my property?
Usually yes. NB-IoT is built for exactly this — it reaches further and penetrates obstacles better than the signal on your phone, so spots that feel like dead zones for calls often still carry sensor data. We confirm coverage for your location before recommending hardware.
When do I actually need satellite, and what's the catch?
Use satellite when a watering point has no cellular coverage whatsoever — deep canyons, remote back-country, or far-flung leases beyond any carrier. The catch is two-fold — it costs more for the hardware and the plan, and low-orbit satellite coverage can be less consistent, since it depends on a satellite being overhead. It's the right tool for true dead zones, not a default.
Does cellular monitoring need the farm's Wi-Fi?
No. Cellular sensors connect to the carrier network directly, so there's no Wi-Fi, router, or hub needed at the tank — that's separate from the farm's internet entirely.
How do I find out which one I need?
Tell us where your watering points are. We check coverage for those specific locations and recommend NB-IoT where it reaches, LTE where it's the better fit, and satellite only where there's no cell signal at all — so you're not paying for more connectivity than the site requires.
