Noise Floor
For each station that is associated to the Array, the Noise Floor window shows
the ambient noise affecting a station’s signal as measured by each IAP. The noise
floor is the RSSI value when the station is not transmitting, sometimes called a
Silence value. In other words, the window shows the noise floor of the station’s
signal at each IAP radio. The noise floor value can be very useful for
characterizing the environment of a station to determine the cause of poor
performance. A relatively high value means that action may need to be taken to
reduce sources of noise in the environment.
Figure 76. Station Noise Floor Values
You may choose to display Unassociated Stations as well with a checkbox at the
bottom of the window.
By default, the noise floor is displayed numerically. (Figure 76) You may display
the relative value using color if you select Colorize Intensity, with the highest
noise indicated by the most intense color. If you select Graph, then the ambient
noise is shown on a representation of the Array, either colorized or numerically
based on your selection.(Figure 77) The stations are listed to the left of the
Array — click on a station to show its values on the Array.
