The Environment panel allows you to configure some of the very
important project parameters that affect the way data
visualizations are computed.
Because different environments have different characteristics in
terms of signal attenuation, diffraction, reflection, etc., you are
Select an environment
from the list. You should select the environment that best
describes the site being surveyed.
For each environment, the application recommends a
A guess range is the diameter of the circle for which the
application predicts WLAN characteristics with a high degree of
certainty. The lower the range, the more accurate the measurements,
but the longer your walkabout path is. The higher the range, the
less accurate the measurements, but the less time you spend
performing a survey. When you conduct a site survey and click on
the map to mark your location, TamoGraph displays your path and
draws the guess range around the route points and your path, thus
giving you a visual indication of the zone that you covered with
your survey. The image below illustrates the walkabout path and
guess range zone drawn along the path.
It is quite all right to decrease the suggested guess range, but
increasing it is not recommended for the reasons explained
For passive surveys, TamoGraph can also compute WLAN
characteristics outside the guess range zone, although such
computations will have a lower degree of accuracy. Check the
Extrapolate data beyond the guess range
box to enable such computations. Enabling this option will mean
will cover the entire map rather than the areas that you actually
surveyed. Enabling this option is not recommended.
For predictive surveys, you can specify the expected

the 2.4 GHz and 5 GHz bands. The default level is -90 dBm for 2.4
GHz and -95 dBm for 5 GHz.
