AirWave 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
l
the office confines. See
Client Training for Stationary Devices - ensures non-mobile clients like desktops or scales will always remain in a
l
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 "Location Training for Stationary Devices" on page
Remote Client Surveys - provides additional attenuation inputs for corners and low-coverage areas without the
l
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
l
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 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
