A consulting engineer is preparing to survey a brownfield deployment for a 6000-sqft building with...

A brownfield deployment scenario involves an existing operational wireless network where a physical remodel will change the RF environment. The engineer ' s task is to assess the impact of new furniture and wall materials on the existing AP placement — a scenario requiring a predictive re-analysis of how changed materials will alter propagation from the existing AP locations. Using a survey tool such as Ekahau with the known AP positions superimposed on updated floor plans, the engineer can reconfigure material attenuation properties to reflect new construction materials and re-run the predictive propagation model. This produces a before/after comparison identifying coverage gaps or interference hotspots introduced by the remodel without requiring physical downtime or temporary infrastructure changes. Option A (sweep analysis) measures existing signal strength but does not model future material changes. Option B (neighbor AP statistics) evaluates the current RF environment using WLC data, not future conditions. Option C (throughput measurements) tests current performance, not future RF impact.
