To remove a statically trained device, select client, and select the Surveys and Training option. Select Delete button

(which will have replaced the Add button) for Static Training.

NOTE: The static locations are automatically saved, so the Save icon (floppy disk) will not appear.

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 AirWave’s 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 211:

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.
