Table 153: Elements Read From Controllers to Increase Location Accuracy (Continued)
W-AirWave provides four main methods to increase accuracy once your access points are deployed:
l Adding Exterior Walls - increases location accuracy by reducing the statistical probability of placements
outside the office confines. See "Adding Exterior Walls" on page 324.
l 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 Defining Stationary Devices.
l 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 "" on page 1.
l Location Probability Regions - Probability regions will increase or decrease the chances of a device being
located within the region. See Defining Floor Plan Regions.
Adding Exterior Walls
Because VisualRF utilizes much existing RF information, generally only external walls are required for accurate
client locations. The VisualRF 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. Navigate to VisualRF>Floor Plans and select a floor plan.
2. Select the Draw Wall button in the Edit menu.
3. The cursor changes to a crosshair icon, indicating that the view is in wall editing mode. Use this cursor to draw
the wall directly over the floor plan, as shown in Figure 187.
