This visualization shows what requirements set by the user are met. The Requirements panel (located on the Properties tab of the right-side panel) allows the user to set thresholds for key WLAN parameters, namely (under the Passive section)::
| § | Minimum signal level (shown as SL on the legend) |
| § | Minimum signal-to-noise ratio (shown as SNR on the legend) |
| § | Minimum signal-to-interference ratio (shown as SIR on the legend) |
| § | Minimum APs required (shown as AP on the legend) |
| § | Minimum PHY rate (shown as PHY on the legend) |
| § | Minimum allowed frame format (shown as FF on the legend) |
| § | Minimum channel bandwidth (shown as CB on the legend) |
The zones where the requirement is not met are marked with the corresponding legend color. If more than one requirement is not met, only one color will be used (priority is given to the requirements closer to the top of the list). If multiple APs are required, the strongest AP will be checked against the requirement list. If all the requirements are met, no color overlays will be displayed.
The meaning of the requirements listed above is explained in detail in the preceding sections of the Analyzing Data – Passive Surveys chapter.
Double-clicking on the Requirements legend on the status bar allows you to configure the color scheme and change its value range.
