Almost every disappointing LoRaWAN deployment traces back to one of two decisions made too quickly: the wrong gateway, or an RF setup that was never tested before the sensors went in. Both are avoidable. Pick the gateway class to match the site, get the antenna and cabling right, and prove coverage with a quick survey — and you install once instead of returning to chase dead spots.
Choose the gateway on environment and power (indoor, outdoor or off-grid), not channel count. Keep the RF chain short and protected — arrestor, low-loss coax, right-pattern antenna. Then survey with a field tester before you commit sensor positions. Do these four things in order and coverage problems rarely appear.
Match the Gateway to the Site
Gateways fall into three practical classes, and the deciding factors are almost always the environment and the power available — not the channel count, which is 8 on nearly everything worth buying.
| Class | Best for | Power & backhaul | Examples |
|---|---|---|---|
| Indoor | Offices, plant rooms, single buildings | Mains / PoE; Ethernet or Wi-Fi | Milesight UG65, Kerlink iFemtoCell |
| Outdoor | Rooftops, poles, campuses, industrial sites | Mains / PoE, optional 4G; IP67 | Milesight UG67, Kerlink iStation |
| Off-grid | Remote sites with no mains or wired internet | Solar + battery; 4G backhaul | Milesight SG50 |
Browse the ranges by class — indoor gateways and outdoor gateways — or, for sites with no power, see our full review of the solar SG50. The rule of thumb: choose on where the gateway lives and how it's powered first, then confirm it runs the network server or packet-forwarder mode you need.
The RF Chain Between Gateway and Sky
A gateway is only as good as what's connected to its antenna port. For outdoor and rooftop installs especially, the signal passes through a short chain of components, and every one of them either protects the system or quietly steals range.
Two links in that chain get overlooked most often. Cable loss is real: every metre of coax costs you signal, and a long run of thin cable can wipe out the benefit of a high-gain antenna, so keep runs short and use low-loss cable (LMR-400 rather than LMR-195 for anything beyond a couple of metres). And on any outdoor mast, a surge arrestor between antenna and gateway is not optional — it's the cheap component that saves the expensive one when lightning strikes nearby. You'll find both, plus mounts and PoE, in our gateway accessories.
Choose the Antenna
Antenna gain isn't "more is better." Gain trades vertical coverage for horizontal reach — a high-gain antenna squashes its radiation pattern into a flatter disc, which is perfect over flat ground and terrible if your sensors are on floors above or below the gateway.
| Antenna | Pattern | Best for |
|---|---|---|
| Low-gain omni (2–3 dBi) | Wide, near-spherical | Indoor and multi-floor, where nodes are all around |
| High-gain omni (5–8 dBi) | Wide but flatter disc | Outdoor 360° coverage over open, flat ground |
| Directional (10–13 dBi) | Narrow, focused beam | Pushing range in one direction, or point-to-point links |
Survey Before You Scale
This is the step that prevents most failed installs, and it takes an afternoon. A LoRaWAN field tester sends uplinks as you walk the site and logs the signal quality each gateway hears, so you validate real coverage before committing to sensor positions.
The FT101 works against The Things Stack or your own network server, sweeps spreading factors to find the best configuration, and even runs a two-unit ping-pong mode to simulate gateway and node before any hardware is installed. For wider network design across multiple locations, our guide to LoRaWAN deployment in Europe covers frequency planning and scaling.
Frequently Asked Questions
How many gateways do I actually need?
Often just one. A single well-placed gateway can cover a whole building or a large outdoor area and handle hundreds of devices. Multi-storey concrete, basements, or sprawling sites may need a second for coverage and redundancy — a survey tells you for certain before you buy.
Do I really need a surge arrestor?
For any outdoor or rooftop antenna, yes. A lightning/surge arrestor sits in-line between antenna and gateway and diverts induced surges to ground. It's inexpensive insurance against losing a far more costly gateway, and many installations mandate it.
Does a higher-gain antenna always help?
No. Higher gain flattens the radiation pattern, extending horizontal reach but shrinking coverage above and below. It's ideal outdoors on flat ground and counter-productive when sensors sit on other floors. Match the pattern to where your nodes are, and prioritise antenna height and clear line of sight.
Can I survey a site before I own the gateway?
Yes — a field tester works against any reachable LoRaWAN network, including public coverage or a temporary test gateway. For an accurate result, though, test against the gateway and antenna you actually intend to install, at the height and location you'll use.
Install Once, Not Twice
Gateway class, RF chain, antenna pattern, survey: make those four calls in order and most coverage problems never appear. The components are inexpensive relative to a truck roll back to a live site, and a single afternoon with a field tester is the cheapest insurance in the whole deployment. Get it right on paper, prove it on site, then scale.
