Wi-Fi that actually works in every room: designing for coverage, not just speed

The most common Wi-Fi setup we walk into on a first site visit is a single consumer-grade router, placed wherever the internet line happens to terminate, expected to cover an entire floor. It might deliver a strong signal in reception and next to nothing two walls and a lift shaft away. That's not a faulty router — it's the predictable result of never designing for the building it's actually in.

Why a site survey matters more than the hardware spec sheet

Concrete, steel reinforcing, lift shafts and even glass partitioning all attenuate Wi-Fi signal differently, and no two floor plans behave the same way. A proper site survey measures signal strength and interference room by room before a single access point is mounted, so placement is based on how radio waves actually behave in that specific building — not a generic coverage radius printed on a datasheet.

Coverage density beats raw access point count

Adding more access points doesn't automatically fix a dead zone; badly placed additional units can create co-channel interference and make things worse. We design for overlapping coverage with correct channel and power planning, so devices roam between access points seamlessly instead of hanging on to a weak signal until it drops.

Designing for device density, not just square metres

A boardroom with fifteen laptops, phones and a video conferencing unit all connecting at once needs different capacity planning to an open-plan office with the same floor area. We size access point capacity around expected concurrent device counts in each zone, not a flat coverage-per-square-metre assumption.

Separating guest, staff and IoT traffic

Coverage is only half the picture — a well-designed Wi-Fi network also separates guest access, staff devices and IoT hardware like access control or cameras onto isolated VLANs, so a compromised guest device or smart TV can't become a route into the systems that actually matter.
