Siemens SCALANCE W1780 Configuration Manual page 243

Description
The display is divided into two areas.
● Client
Represents the measurement of the client.
● Access point
Displays the measurement of the access point with which the client is currently connected.
This requires that the setting "Bidirectional Recording" is enabled and that a firmware
version > 6.1 is installed on the access point. The access point sends its data to a maximum
of 3 clients on which signal recorders are running. The access point data is not displayed on
other clients.
Both areas each contain two graphics.
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.

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.
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
