3. Select the Surveys and Training option.
4. Select the appropriate transmit power for the wireless client. Leave the default to 30mW if you are unsure.
5. Select the Duration or the time that you want to sample the client's signal measurements. Longer durations
will increase Path Loss accuracy and location accuracy.
6. Select OK to begin the survey.
To display survey locations, select the Display menu and select Surveys. Note the following information about
this procedure:
Ensure the client will remain in the same location for at least the duration of the survey.
You should delete and resurvey an area or a floor plan after a remodel or significant interior movement.
Surveys should be conducted during normal business hours to reflect normal RF activity on the floor.
11a clients automatically inherit the proper transmit power from the 11g configuration. Example: 30mW Pre-
2006 laptops equate to 20mW for 11a clients.
AirWave dynamically assigns a transmit power to every client based on OUI as shown in Table 148. This step
increases the accuracy for surveys by allowing an override.
Adding Regions
You can specify regions for areas designated as Wiring Closets and for Location Testing, Location Probability,
and Planning.
