Need network between two buildings? A wireless bridge can do it — no trenching, no conduit, no waiting on the phone company. But the gap between “it works on the box” and “it works on your roof” is where most DIY attempts die. Here’s the honest version.

What makes a bridge work

Point-to-point wireless lives or dies on five things: clean line of sight, stable mounting points, predictable power, surge protection, and radios matched to the distance and frequency band. Get all five right and a bridge runs for years without attention. Miss one and you’ll be rebooting it every time the wind picks up.

The survey comes before the purchase, not after. Trees grow, buildings go up, and roof access that looked fine on Google Earth turns out to be a locked hatch. We verify line of sight, mounting options, power, and interference on site — then recommend hardware.

What kills a bridge

The usual suspects: trees in the Fresnel zone (not just the visible line of sight — the signal needs clearance around it too), weak mounts that drift out of alignment, 5 GHz congestion in dense areas, and weather exposure on cheap enclosures. Every one of these is preventable with planning; every one is expensive to fix after the fact.

A word on “long-range Wi-Fi”

You may have seen records for Wi-Fi links spanning mountains and deserts. They’re real — directional antennas, careful alignment, and favorable terrain can do remarkable things. But a world-record link doesn’t mean ordinary Wi-Fi covers miles through walls, trees, and hills. Practical outdoor links need realistic throughput expectations: a bridge that delivers a stable 300 Mbps between your buildings beats a “gigabit” link that drops every afternoon.

Wireless vs. fiber vs. trenching copper

Sometimes the right answer isn’t wireless at all. If conduit already exists or trenching is straightforward, fiber between buildings is more reliable and faster. If the distance is short and there’s a clean cable path, wired always wins. We evaluate all three and recommend the one that fits the property — not the one with the highest margin.

Schedule a site survey — we’ll tell you whether a wireless bridge is realistic for your buildings, and what it would actually take.
