In a Wi-Fi site survey, what diagram shows signal strength and channel utilization at different locations?

• A. Heat map
• B. Signal diagram
• C. Coverage map
• D. Location heat chart

Answer: (A)

Visualizing how signal strength varies across a site is shown with a heat map. In a Wi‑Fi site survey, a heat map maps measurements of signal strength (and often channel utilization) to specific locations, using color intensity to indicate stronger or weaker coverage. This makes it easy to spot dead zones, overlap, and congested channels, guiding where to place access points or adjust channels. A coverage map is broader and doesn’t always convey the detailed gradient of signal strength and usage across the space. The other terms aren’t standard outputs for this purpose. So the diagram that best communicates signal strength and channel utilization at different locations is the heat map.
