RF Propagation Theory

Signal Mapping is used to predict wireless performance before physical deployment. It accounts for the Log-Distance Path Loss model, where signal strength decreases exponentially with distance.

RSSI (Received Signal Strength Indicator): Measured in decibels relative to one milliwatt (dBm). A value of -30 dBm is excellent, while -67 dBm is the minimum required for stable voice-over-WiFi, and -90 dBm usually indicates complete disconnection.

Heatmap Visualization: By using color gradients, engineers can identify "dead zones" where signal penetration is blocked by walls or heavy interference, allowing for optimal AP placement.
