300-425 · Question #222

Refer to the exhibit A wireless consultant is performing an onsite survey using AirMagnet Survey PRO. What must be configured on the floor map so that the results appear properly?

The correct answer is B. Calibrate the dimensions.. Before AirMagnet Survey PRO can accurately overlay RF data onto a floor plan, the map dimensions must be calibrated to establish the real-world scale of the image.

Why each option

Before AirMagnet Survey PRO can accurately overlay RF data onto a floor plan, the map dimensions must be calibrated to establish the real-world scale of the image.

AShow details of the user density.

User density details are an optional visualization overlay and have no effect on whether survey RF data is plotted accurately on the floor map.

BCalibrate the dimensions.Correct

AirMagnet Survey PRO requires the user to calibrate the floor map by defining a known distance on the image, which establishes the pixel-to-foot or pixel-to-meter ratio used for all subsequent measurements. Without this calibration step, the tool cannot correctly translate collected signal measurements to physical locations on the map, causing all survey results - coverage heatmaps, signal strength plots, and channel data - to appear inaccurately placed or completely distorted.

CDisplay details of the desk numbers

Displaying desk numbers is a cosmetic annotation feature and is not required for survey results to render correctly on the floor map.

DAdd inter-floor bleed

Inter-floor bleed is a configuration for multi-story environments to account for RF penetration between floors and does not affect the basic accuracy of single-floor survey result display.
