Heat is the constraint people forget. Equipment rated for an air-conditioned comms room behaves differently in a roof space at the end of a Goldfields summer, and the failure is rarely dramatic — it is a slow drift into instability that reads as “the Wi‑Fi is bad” long before anything actually stops. Specifying for the temperature the site really reaches is cheaper than returning to it.
Existing cabling was less of a shortcut than it looks. Northam’s phone cabling could have carried a wired link, but it ran to the bedside tables where the phones were — not to anywhere a network wants to begin. Coolgardie had no phone cabling at all. That left new cable, and new cable between buildings means trenching across a property guests are staying on.
Linking the buildings over the air rather than through the ground changed what was affordable. Both point-to-point and point-to-multipoint links were used, each where the site suited it: Northam fans out to the rest of the property from a single vantage point at the office, while Coolgardie, built later when better equipment was available, runs separate direct links out to each building. Adding a building later is a mounting job rather than an excavation, and neither property lost a garden bed to a trench.
Neither property is meshed, and that is deliberate. A mesh would carry the traffic between buildings on the same radios serving the guests, so every hop spends bandwidth and adds delay — worst at the far end of the site, which is exactly where the coverage problem started. A dedicated link keeps the path between buildings separate from everything using it.
The two motels are separate businesses in different regions, and each got its own network — but they got it built to the same pattern, because the problem was the same shape at both. Guest separation was part of that pattern from the start: guests sit on their own network with no route into the motels’ own systems. That is also what makes the current work possible. Once a motel’s own systems are on a network of their own, monitoring them is an extension of the design rather than a new one.
