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