Noise Floor
For each station that is associated to the AP, 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. 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 77. 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 77) 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 AP, either colorized or numerically
based on your selection.(Figure 78) The stations are listed to the left of the AP —
click on a station to show its values on the AP.
