This visualization shows the areas covered
by the APs. An area is considered covered if the signal is
strong enough for the clients to communicate to the AP. You can
select and deselect one or several of the APs to see individual or
group coverage areas. Coverage areas are color-coded: For each AP,
a small colored square is shown next to the AP icon. The
corresponding color is used to display the coverage area contour or
fill.
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 following options on
the Visualization
Settings panel
(located on the Options tab of the right-side panel) affect the way
AP coverage areas are analyzed and visualized:
·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.
·AP
coverage areas – This
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, 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.
