Noise layer

The noise layer visualises ambient RF noise across the floor plan using a grayscale heatmap. Noise propagates in three dimensions — local sources on the current floor are modelled in 2D with wall attenuation, and noise from adjacent floors arrives attenuated by their floor-slab values.

Enabling the noise layer

Click the Noise toggle in the toolbar. The heatmap appears as a semi-transparent overlay. A scale must be defined first.

Background noise floor

The background noise field sets the global noise floor for the entire plan. The default is −135 dBm, which corresponds to a completely clean environment.

Adding local noise sources

1. Click the waveform icon or select Noise → Edit to enter noise edit mode.
2. Click a cell to open the gradient editor and set the emission level in dBm.
3. Click Apply to save, or Clear to remove an existing source.

3D noise propagation

Noise sources on adjacent floors contribute to the current floor's noise map. Sources from the floor above pass through that floor's slab attenuation; sources from below pass through the current floor's slab attenuation.
