If the WLAN being surveyed has SSID broadcasting disabled, enable
it for the duration of the survey, if possible. This will
facilitate the identification of the APs you would like to have
included in the data analysis.
Fully charge your laptop and be prepared to recharge it. Having an
extra battery on hand would not hurt. However, if your laptop goes
into standby or hibernation while you are performing a survey,
TamoGraph will save the data and stop the active survey. You will
be able to continue where you stopped.
When you conduct GPS surveys, the survey process is fully
automated; normally you do not need to touch any application
controls, so you may want to close the laptop lid. If you plan to
close the lid, be sure to configure the laptop power settings to
prevent the laptop from going into standby or hibernation when you
close the lid.
Plan your walkabout path in advance. You may want to write down
numbers on the site map marking your path. Then, while surveying,
you would just have to walk along the path and click on these
numbers. When planning your path, be sure to plan it so that you
capture the perimeters of the rooms rather than their center. This
improves data quality.
If you care about signal leakage outside the building, plan your
path along the outside building perimeter. Without this perimeter,
TamoGraph will not be able to estimate the signal strength outside
Be sure to cover places of special importance, such as conference
rooms or the CEO's office. Survey them with closed doors. Closed
doors may considerably decrease the signal level, so surveying with
open doors may give you a signal coverage map that is too
If the site is large, consider splitting the site map into several
parts, as working with smaller maps is easier. Besides, the report
generated by TamoGraph will be more meaningful if separate maps are
used for separate zones. A large map just will not be legible if
has to be displayed on one page. You can have as many maps as you
wish in a single TamoGraph project. The same applies to multi-floor
If the site is large, you can also split the job between several
people sharing the same project. The correct way of doing this is
described in the Survey Job Splitting chapter.
If you are going to survey a large facility with many employees
during business hours, make an announcement telling them that
someone will be conducting a survey. Ideally, this will prevent
them from distracting you with questions.
