Scaling the map is an essential step before conducting a pre-deployment passive RF survey because it ensures that the physical layout of the area where the survey will take place is accurately represented. Proper scaling allows for precise measurements and analysis of distances, frequencies, and potential obstacles that may affect wireless signal propagation. It provides a foundational framework upon which the rest of the RF survey will be based, enabling the surveyor to accurately predict how the RF environment will behave.

Additionally, an accurately scaled map helps identify areas that may require more detailed analysis during the survey, ensuring that all relevant factors are taken into account when planning the wireless network deployment. Without a correctly scaled map, the physical context of the RF survey could lead to inaccurate assumptions about coverage areas, signal strength, and overall network performance.
