LoRaWAN vs Cellular — IoT Comms Guide

How to connect sensors and trackers across farms and estates — without the jargon.

Connecting sensors, tank monitors and trackers spread across acres of farmland or estate is a different challenge to wiring up a building. Three wireless technologies dominate rural IoT: LoRaWAN (your own private long-range radio network, tiny power draw, no SIMs), cellular 4G/5G — including LTE-M and NB-IoT (uses the mobile networks, works wherever you have signal) and Sigfox (a low-cost public network for occasional alerts). This guide explains each in plain English and weighs them up on range across open land, battery life, how much data they carry, running cost and real coverage in remote spots — so you can pick what actually fits your holding.

Key features

• How Each One Works. LoRaWAN, cellular and Sigfox explained without the acronyms — what carries your data, who runs the network and where the SIM (or gateway) sits.
• Range Across Open Land. LoRaWAN reaches 2–15km from a single gateway over fields; cellular follows mast coverage; Sigfox stretches 10–50km. Why hills, hedgerows and woodland matter more than the spec sheet.
• Battery & Off-Grid Power. LoRaWAN and NB-IoT sensors can run 3–10 years on a coin cell or small pack — vital where there's no mains. What drains them faster, and how reporting interval changes everything.
• Running Cost Over Time. Sensor price, gateway outlay versus per-SIM fees, and the true five-year cost of monitoring 50 or 100 devices on one farm or estate.
• Rural Coverage Reality. Where the mobile networks thin out on remote land, where a private LoRaWAN gateway fills the gap, and how to check before you commit.
• Picking by Job. The right choice for soil and weather sensors, gate and tank alerts, machinery trackers, water troughs and roaming livestock.

Which one should you go for?

Start with where your kit lives. If everything sits on a single holding — a farm, estate or yard — LoRaWAN is normally the most economical, because one gateway covers the whole place and there are no SIM bills mounting up sensor by sensor. If your devices are scattered across separate parcels of land, or they move (vehicle and trailer trackers, portable pumps, roaming stock), cellular 4G/5G earns its keep because it reports from anywhere with a mast signal.

Then think about how much you need each device to say. Cellular comfortably carries images, frequent updates and near-live data. LoRaWAN is built for short, regular readings — soil moisture, gate status, trough and tank levels — every few minutes. Sigfox suits the bare minimum: a once- or twice-daily alert. Most estates land on LoRaWAN for the fixed sensor network and cellular for whatever moves or needs to shout the moment something happens.

Frequently asked questions

Which works out cheapest to run?

Sigfox is cheapest per device but only carries tiny, infrequent messages. LoRaWAN wins once you're at scale — after the gateway, there's no monthly fee per sensor. Cellular costs the most per device because every unit needs a data SIM, but you skip buying any infrastructure.

What's best for a working farm or estate?

For fixed sensors on one holding, LoRaWAN is usually the smart pick: a single gateway blankets the land, sensors last years on one battery, and you pay nothing per device. Add cellular for anything that leaves the property or needs instant alerts.

Can I run more than one technology together?

Absolutely. A common rural setup uses LoRaWAN for the static sensors dotted around fields and buildings, and 4G/5G for trackers on machinery, trailers or stock that move off-site. Our platform pulls both onto one dashboard.

Does a LoRaWAN gateway need planning permission?

In most cases no. A gateway is a small, low-power unit not unlike a broadband router or a satellite dish, and can usually be mounted on a barn, pole or roof without consent. Listed buildings and conservation areas are worth checking first.

What if my gateway goes down?

If a LoRaWAN gateway fails, its sensors stop reporting until it's back up. For critical jobs on remote land we suggest a spare on the shelf, or putting your must-have alerts on cellular as well so they never go quiet.

Do these work inside barns and steel buildings?

All three send indoors, but thick stone and metal cut the range. Cellular usually copes best inside a steel-frame shed, LoRaWAN next, with Sigfox the most affected. Mounting sensors near openings or higher up helps every time.

How fast can I be up and running?

Cellular is instant — slot in a SIM and it reports. LoRaWAN needs the gateway set up first, around half an hour, after which sensors join on their own. Sigfox units start talking the moment they're powered on within coverage.
