The following settings affect the way
TamoGraph displays some of the visualizations:
Area is
considered covered if signal strength is at least
– This setting defines the AP
coverage area based on the minimum signal strength. If the signal
strength is below the specified level, the area is considered to be
not covered, which means that some data values will not be computed
for the area (such areas will appear as white spots). The
definition of “strong enough” is rather subjective because certain
signal strength might be sufficient for low data rates, but
insufficient for the high data rates required for such applications
as VoIP. Additionally, 802.11 adapters vary in sensitivity, and
some adapters might be able to provide good connectivity in zones
where other adapters fail to connect altogether. The default value
is -70 dBm. This setting is applicable to the following
visualizations:
Signal-to-Interference Ratio, AP Coverage
Areas, and
Number of
APs.
Average
network utilization –
This setting defines how heavy the interference is from the
interfering APs. If the interfering signal strength is high, but
the network utilization is low, the interfering AP does not create
much interference. A typical office WLAN has a network utilization
of between 10% and 25%. Adjust this setting to match the actual
value for your WLAN. This setting is applicable to the following
visualization:
Signal-to-Interference Ratio.
AP coverage
areas – This setting
allows you to change the color coding method used for displaying
coverage areas. In No fill, contours
only mode, the
application draws contours of the coverage areas without filling
the areas with colors. In Fill and mix
colors mode, the AP
coverage areas are filled with colors; when areas overlap, the
application draws a striped pattern, alternating the colors of the
respective APs. In Fill, strongest AP on
top mode, AP coverage
areas are filled with colors; when areas overlap, the application
draws the color of the strongest AP. In Fill, weakest AP on
top mode, AP coverage
areas are filled with colors; when areas overlap, the application
draws the color of the weakest AP. This setting is applicable to
the following visualization:
AP Coverage
Areas.
Grayscale
obstructions – This
setting controls whether virtual objects (used in predictive
surveys) are displayed in color or grayscale mode. Available
options are Always,
When
applying visualizations,
and Never.
