When a business needs Wi-Fi, the default path looks like this: call a vendor, get a quote, place an order. The vendor often throws in a "free site survey" and a layout diagram. It feels like due diligence. It isn't.
That layout is designed to sell you hardware — specifically, the hardware that vendor happens to carry. The number of access points, their placement, the controller they recommend — all of it is shaped by inventory and margin, not by the specific coverage requirements of your building.
Technology Inc. has walked into dozens of offices, schools and hotels where this has happened. The Wi-Fi doesn't reach the boardroom reliably. The warehouse floor has dead zones. The hotel guest complaints won't stop. And when you call the vendor back, the answer is always more hardware.
What a vendor design actually optimises for
A vendor's primary goal is to sell you as many units as possible while keeping the quote low enough that you don't ask too many questions. This creates a specific pattern of failure:
- Too many cheap access points instead of fewer, better-placed ones — creating co-channel interference that makes your network slower the more people are on it.
- No heatmap analysis — the layout is based on a floor plan, not on the actual radio frequency environment of your building. Concrete walls, metal fixtures and glass all affect Wi-Fi propagation in ways that only a proper RF survey captures.
- No documentation — you get a quote, not a specification. When the vendor changes, the next one starts from scratch.
- No consideration of future density — your current 20-person team won't stay at 20 people. A vendor design for today's headcount often fails within 18 months.
The real cost isn't the hardware. It's the lost productivity, the IT support hours, the repeat vendor calls and ultimately the rip-and-replace project when the original installation can't be salvaged. We've seen organisations spend three times their original budget fixing a "free" Wi-Fi design.
What a neutral design looks like
A properly conducted Wi-Fi design engagement starts with a brief — understanding how many users the network needs to support, what applications they run, where the coverage boundaries need to be, and what the client experience should feel like in every area of the building.
From there, the design process involves:
- A site walk or detailed floor plan review to identify physical obstacles, existing infrastructure and likely interference sources.
- RF propagation modelling — using software to simulate how radio signals will behave in the specific environment, before any hardware is selected.
- AP placement designed for the environment, not for the vendor's catalogue — including mounting height, antenna orientation and channel planning.
- A Bill of Quantities (BOQ) that specifies access point count, category of hardware and any ancillary equipment — without naming a specific brand. This lets any qualified integrator quote against the same scope.
- A design document you own — heatmaps, floor plan overlays, AP schedules and a brief specification that survives vendor changes.
What changes at procurement
When you have a design document rather than a vendor quote, something changes in the procurement dynamic. You can send that document to three different integrators and ask them to price it. They're all quoting the same scope, so the comparison is apples-to-apples. You're not comparing different numbers of access points from different brands — you're comparing integration quality and price.
In our experience, this process typically saves 15–30% on implementation cost compared to accepting the first vendor quote. And the installation is better, because the integrator is executing a proper design rather than improvising one.
A well-designed Wi-Fi network should work reliably for 5–7 years. The access points you buy are commodities. The design is the investment.
When to commission a design
The ideal time to commission a Wi-Fi design is before you have a problem — during a new fit-out, before a significant headcount increase, or when planning a campus expansion. At that point, the cost of getting it right is minimal.
The second-best time is right now, even if your current network is struggling. A design engagement will tell you whether your existing infrastructure can be salvaged with repositioning and reconfiguration, or whether a more significant intervention is needed. Either way, you'll have a plan — and you won't be relying on a vendor to give you one.
