What is a wireless site survey and when is it needed?

Skip to main content

Last updated: 27 September 2026

A wireless site survey is a professional assessment of your building to plan, check or fix your Wi-Fi. Engineers measure signal strength, interference and capacity so that access points are in the right places and every area gets reliable coverage.

When do you need one?

  • Moving into a new office or refitting an existing one
  • Wi-Fi drops out, is slow, or has dead spots
  • More people or devices are connecting than the network was designed for
  • Adding video calls, VoIP phones or other bandwidth-heavy services
  • Covering difficult spaces such as warehouses, schools, older buildings with thick walls, or multiple floors

What does a survey include?

  1. Predictive survey: modelling the building from floor plans to design access point locations.
  2. On-site survey: measuring real signal, interference from neighbouring networks and building materials.
  3. Heatmap report: a colour-coded map showing coverage, with recommendations. See what is a heatmap?
  4. Validation: after installation, a follow-up test confirms the design works.
