Quick answer
A Wi-Fi site survey measures signal strength, interference and capacity across a building, often shown as a heatmap. It reveals dead spots, thick walls and busy channels, and tells you where access points should go and how many are needed. Planning first avoids overspending on extra units or living with weak coverage.
