Adding Exterior Walls; Location Training For Stationary Devices - Dell PowerConnect W-Airwave User Manual

Client Training for Stationary Devices - ensures non-mobile clients like desktops or scales will always remain

in a defined static location. Statically assigning non-mobile devices reduces the CPU load on your server
because VisualRF does not evaluate any signal metrics for this MAC address when associated with an AP on
the floor plan. See
Remote Client Surveys - provides additional attenuation inputs for corners and low-coverage areas without

the burden of actually carrying a laptop to the physical location. See
Location Probability Regions - Probability regions will increase or decrease the chances of a device being

located within the region. See

Adding Exterior Walls

Because VisualRF utilizes much existing RF information, generally only external walls are required for accurate
client locations. VisualRF's Dynamic Attenuation feature uses AP-to-AP information to calculate attenuation for
interior areas, negating the need to enter interior walls. If your devices support AP-to-AP information in the table
above, you should only draw exterior walls.
1. Select Draw Walls icon in the Edit menu.
2. The cursor changes to a crosshair. Use this to draw the wall directly over the floor plan, as shown in
Figure 204 Drawing a wall
3. To move or resize the wall, select the Wall icon in the Edit menu again. The cursor changes to a hand, and the
ends of the wall is highlighted. Click and drag the end point handles to change the wall, as shown in

4. Once all walls are provisioned on the floor plan, select Save (floppy disk icon above the zoom bar).
NOTE: Drawing only outside walls is recommended. 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, as shown in
