The graph’s color indicates the utilization % (i.e. how often RF signals are detected) for each frequency.
Blue color data points indicate very low utilization
Green color data points indicate low utilization
Yellow color data points indicate moderate utilization
Red color data points indicate high utilization
Use the Marker function (
) to view the level and utilization values for the frequency.
Use the Show AP function (
) to view the AP scan information overlaid on the spectrum graph.
Use the Signature function (
) to identify interferers’ signatures.
Spectrum Density Graph
9.4.1 Using the Signature Function
WiFi and non-WiFi sources of RF signal in the 2.4 GHz and 5 GHz frequency bands emit a spectrum that is often recognizable by
its shape. This shape is called a “signature”. By recognizing a signature on the density spectrum, users can identify the device type
source of interference.
A library of standard WiFi and non-WiFi signature shapes are accessible through the Signature function key and are available in
the Density Graph view.
