Location Training For Stationary Devices; Adding Client Surveys - Dell PowerConnect W-Airwave User Manual

5. Select OK to continue.
NOTE: Dell recommends only drawing outside walls. If you are seeing inaccurate client locations or heat maps after entering
exterior walls, proceed to Client Surveys. If you still experience problems, then you can proceed to adding interior walls.

Location Training for Stationary Devices

QuickView provides the ability to statically assign a permanent x, y coordinate to stationary devices like PCs,
Scales, and Point-of-Sale terminals. This will reduce the calculation requirements on the VisualRF location
service and increase the accuracy of the RF characteristics of individual floor plans.
1. Drag the client device to the proper location.
2. Select the device and a popup menu appears. From that menu, select Surveys and Training.
3. Click the Add button for Static Training.
To remove a statically trained device, select client, and select the Surveys and Training option. Select Delete
button for Static Training.
NOTE: The static locations are automatically saved, so the save button (floppy disk icon) 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 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 10 Client Surveys
3. Select the Surveys and Training option.
4. Select the appropriate transmit power for the wireless client. 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.
