Siemens SCALANCE W1780 User Manual

The second graphic contains the following elements:
● Bar (left)
In the bar on the left-hand side the transfer attempts and the data rate of the client / access
point are displayed according to the color scheme.
● 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. The individual colors are described again under the graphic.
● x axis
The x axis shows the course of the measurement in random samples and seconds.
● Measurement data
– Client
The measurement data shows the transfer attempts according to the color scheme
shown. The transfer attempts are shown as a bar. The data rate of the sent data packets
is represented as a line. If the client changes access points during a measurement
(roaming) or reconnects, this is displayed by a vertical black line.
– Access point
The measurement data shows the transfer attempts according to the color scheme
shown. The transfer attempts are shown as a bar. The data rate of the sent data packets
is represented as a line.
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 data is displayed.
Beside the graphics the following values are displayed:
● Status
Shows whether or not the signal recorder is recording values.
● Current Sample
The number of the current measurement
● CL RX-Signal [dBm] / AP RX-Signal [dBm]
The effective user signal of the client / access point in dBm
● CL NF [dBm] / AP NF [dBm]
The background noise of the client / access point in dBm
● CL Retries [%] / AP Retries [%]
The transfer repetitions of the client / access point as a percentage.
● CL RSSI / AP RSSI
The raw value of the RSSI (Received Signal Strength Indication) of the client / access point
● CL TX-Rate [Mbps] / AP TX-Rate [Mbps]
The average data rate of the sent data packets during the current random test
● CL M-Signal [dBm]
If the client has an iPCF-MC connection, the user signal of the management channel is
displayed.
● Roaming Counter
The roaming counter shows how often the client has changed access points during the
recording. After 4,294,967,295 changes, the counter is reset.
