What a Wireless Site Survey Actually Tells You

Most bad WiFi is not a hardware problem — it is a planning problem. Access points get mounted where it was convenient to run a cable, not where the coverage data says they belong. A wireless site survey replaces that guesswork with a map.

The two kinds of survey

A predictive survey models coverage from your floor plan, wall materials, and ceiling heights before anything is installed — ideal for new builds and budgeting. An on-site survey validates the real world by walking the space with calibrated tools, measuring actual signal, interference, and noise.

What it actually measures

• Coverage — signal strength everywhere people and devices actually are.
• Capacity — how many devices each area must support, not just whether there is signal.
• Interference — competing networks, microwaves, and other RF noise.
• Channel plan — so neighboring access points do not step on each other.
• Roaming — whether moving devices hand off cleanly between access points.

Signal everywhere is not the goal. The right signal where devices actually are — that is the goal.

Why guessing costs more

Skipping the survey usually means buying too many access points (or too few), mounting them poorly, and then paying again to fix it after users complain. A survey-first approach gets it right once. It is the foundation of our wireless services, and it pairs directly with structured cabling and PoE planning.

Frequently asked

Do I need a predictive or an on-site survey?

Predictive is great for new construction and budgeting; on-site validates real conditions in an existing space. For critical environments we recommend both.

Can a survey fix existing WiFi dead zones?

Yes. A validation survey pinpoints the gaps and we adjust placement, power, and channels — adding access points only where the data shows they are needed.
