Conducting the Survey
After you apply any AirMapper Settings that you have
changed, you can begin the site survey. Before beginning, you
may want to have the following information for yourself (or
for any person conducting the survey for you remotely):
A predetermined and systematic survey path through
the site that thoroughly covers all areas you want
included in the survey.
The Signal Propagation distance so that the you know
approximately how far to go b
etween survey
measurements to have some reasonable overlap
between measurement areas.
To collect the survey data:
1
Go to the place where you want to begin the survey.
2
Tap Start on the main AirMapper screen.
3
Begin following your survey path through your site.
When you want to take a measurement, tap the floor
plan image at the point that corresponds to your physical
location. A red measurement area appears on the floor
plan while the AirCheck G2 gathers data. The area turns
green when the measurement is complete, and the point
of the measurement appears at the center (Figure 31).
(The size of each colorized area depends on the Signal
Propagation value used in the
AirMapper Settings.)
