Calibrating Floor Maps in AirMagnet Survey PRO

The core concept here is the prerequisite step for accurate radio frequency (RF) modeling in wireless survey tools. Before any signal propagation analysis or heat map generation can occur, the software must understand the physical scale of the environment.

Calibrating Dimensions (Option C) This is the correct action. In AirMagnet Survey PRO and similar Wi-Fi planning tools, you must first define the scale of the floor plan by setting a known reference distance (e.g., marking two points on the image that represent a specific real-world length). Without this calibration, the tool cannot calculate path loss, coverage areas, or antenna radiation patterns accurately because it does not know how many meters or feet correspond to a pixel or inch on the map. As noted in community feedback, "scaling the dimensions" is always the first step when creating a project in Wi-Fi analysis software.

Why other options are incorrect:

• Add inter-floor bleed (Option A): This feature allows RF signals to propagate between floors based on material attenuation settings. While important for multi-story surveys, it requires a calibrated map as a foundation; you cannot configure bleed effects meaningfully if the vertical distances are undefined.
• Show details of user density (Option B): User density is a parameter used for capacity planning or predictive modeling, not a geometric requirement for displaying signal results on a map.
• Display details of desk numbers (Option D): This is purely aesthetic or organizational metadata. It has no impact on the RF physics or the appearance of signal strength results.

The boundary to recognize is between geometric setup (calibration) and content overlay (density/desk numbers). Calibration is foundational; everything else depends on it.
