What Is a Wi-Fi Site Survey and Why Offices Need One

A Wi-Fi site survey is a structured check of how wireless signal behaves inside your building. Instead of guessing where access points should go, an engineer measures coverage, interference and capacity in the real space.

Why buildings behave differently

Walls, glass, lifts, metal shelving and even the number of people in a room change how a signal travels. Two offices of the same size can need very different layouts. A plan drawn from a floor plan alone cannot see these effects.

What a survey usually looks at

• Coverage: where the signal is strong, weak or missing
• Interference: nearby networks and other equipment using the same channels
• Capacity: how many devices each area needs to support, not just how far the signal reaches
• Access point placement: where devices should be mounted, and how many are needed
• Cabling and power: how each access point will be connected

When it is worth doing

• Before a new office fit-out or move
• When staff report dropped calls or slow Wi-Fi in certain rooms
• For multi-floor buildings, warehouses, clinics and showrooms
• Before replacing an older wireless system

What you should receive

A good survey ends with something you can act on: a placement plan, a list of what is needed, and notes on any wiring work. That lets you compare quotes on the same basis.

Next step

If Wi-Fi is a recurring complaint, a review of the wired network behind it is often useful too. NetworkAE plans and installs wireless systems through Wireless Network Deployment, and the free network assessment is a no-obligation way to start.
