Adding Client Surveys
Client surveys within VisualRF use data from access points to understand which clients those access points hear and at
what signal strength. The legacy flash-based VisualRF UI allows you to run client surveys to increase the accuracy of
the attenuation grid by taking real signal samplings from client devices associated with the WLAN.
This feature is not available in the default HTML5 VisualRF UI.
Key differentiators of AirWaves client surveys are:
1. They take readings from the access points and not the client.
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 231:
