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 button 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 212:

3. To move or resize the wall, select the Draw Walls button 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 Figure 213:

 To change the attenuation of a wall, right-click the wall and select the appropriate building material.
 To delete a wall, select the wall and press the Delete key. You can also right-click on a wall and select
Delete This Wall from the popup menu.
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.
