Technical description and operating manual ST 167 and ST167W5

Also, update stops by pressing
button (appearance of selection rectangle on first line).
Grey – color of WAP, which level is lower than noise level on given channel. This indication is shown for
around 30 sec. During this time WAP status is being analyzed. If level will not increase higher than given in MENU
– WAP disappears from list, if increases – line color will change to black.
For selected WAP analysis press
button.
Information about selected network will appear on screen: network name, MAC
address, channel number and signal level from HS.
Signal level indication, unlike the other information, is not static. Level will change
depending on moving of ST167 relatively to the WAP in real time.
After working with this screen and subsequent returning to W- iFi networks
searching, line color will become black – WAP is not new anymore.
Returning to networks list – repeated pressing on
button.
By pressing on
button transition to signal level indication on this channel is
done. And if on fig.26 we can see only WAP signal level, then on fig.27 signal level on given
channel is shown and it consists of sum of signals:
- WAP (on fig. 26 it is - 63dBm)
- signals from devices, connected to selected WAP.
- signals from other radio emitting devices, using Wi-Fi range.
Ability of 2 signal level values operational control (fig.25 and 26) gives wide ability range for Radio emitting
devices detection in WiFi network range (see additional recommendations)
6.9 BASE STATIONS LEVEL MEASUREMENT
The ST167 is capable to measure level of base stations of the standards with
transmit and receive channels divided by frequency (GSM900, 1800, 3,4G), as well as
the level of DECT base stations based on signal timing analysis of the mentioned
standards. For this select the "MANUAL" mode, enter the MENU, select "Band..." and
tick the "Base stations in manual mode". Return to the level indication screen by
sequentially pressing
the "MAN MOB" inscription in the upper left corner will
change to "MAN BAS" (Fig.27).
6.10 TRAFFIC
When the "T" symbol is selected, the unit provides the intensity value of
transmission of any digital data in the 2.4 and 5GHz ranges (Fig. 28). This indicator DOES
NOT show the level of the signal. The result can be in the range from 0% to 99%. The
values <10% mean negligible data transfer activity. Values >50% correspond to a large
stream of digital data. For example, this way you can detect the operation of a WLAN
camera, which is characterized by a high volume of data being transmitted.
It should be noted that it is estimated data transmission and reception even large
amounts of data (e.g. video) will not cause an increase in traffic.
