Adding Client Surveys

Client surveys provide a method for increasing the accuracy of the attenuation grid by taking real signal samplings
from client devices associated with the WLAN.
Key differentiators of AMP's client surveys are: (1) they take readings from the access points and not the client
and (2) they take numerous samples. This produces a more accurate representation because signals obtained
from the client's card (the signal level at which a client hears the AP) can vary from vendor to vendor.
The signal levels at which APs can hear a client are already normalized. Using multiple samples alleviates spikes or
troughs that come from using a single sample.
To start a client survey, follow these steps:
1. Drag the client to the proper location.
2. Select the client to see the Properties pop-up menu, as shown in
Figure 207 Client Surveys
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.
