The first graphic contains the following elements:
● Scroll bar
With the scroll bar, you can look through the entire measurement. To do this you can use
the "<<" and ">>" buttons or the arrow keys on the keyboard.
● Bar (left)
In the bar on the left-hand side the user signal of the client / access point is displayed in
real time according to the color scheme. The gray line shows the background noise.
If the client has an iPCF-MC connection, the user signal of the management channel is
shown with a black line.
● Color scheme
The range > -35 dBm (blue) is the overmodulation range, in other words the WLAN signal
is too strong and is received overmodulated. As of approximately -60 dBm (yellow) the
WLAN signal is weaker.
● x axis
The x axis shows the course of the measurement in random samples and seconds.
● Measurement data
– Client
The measurement data shows the value of the effective user signal according to the
color scheme shown. The gray line shows the background noise.
If the client changes access points during a measurement (roaming) or reconnects,
this is displayed by a vertical black line. On the line the new AP system name and the
BSSID are shown.
If during a measurement the client has no connection to an access point, no user
signal is displayed. To make it clear that there is no connection to an access point, the
BSSID is set to 00:00:00:00:00:00 and shown in red.
If the client has an iPCF-MC connection, the user signal of the management channel
is shown with an additional black line.
– Access point
The measurement data shows the value of the effective user signal according to the
color scheme shown. The gray line shows the background noise.
If the client changes access points during a measurement (roaming) or reconnects,
this is displayed by a vertical black line.
If the access point does not support the setting "Bidirectional Recording" no user
signal is displayed
