AMP provides four main methods to increase accuracy once your access points are deployed:
Adding Exterior Walls - increases location accuracy by reducing the statistical probability of placements

outside the office confines. See
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 (Brick Wall) in the Floor Plan Edit Tools widget. A green border appears around the
icon.
2. The cursor changes to a crosshair. Use this to draw the wall directly over the floor plan.

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.

3. Once all walls are provisioned on the floor plan, select Save (floppy disk icon). A Save Changes dialogue box
appears.
4. Select OK to commit the change. A Changes Saved dialog box appears.
