Increasing Location Accuracy
The Location Service will use all RF information available to increase location accuracy of clients, tags, and rogue
devices. Understanding your infrastructure's inherent capabilities helps you learn the extra effort required to
ensure location accuracy.
There are three key elements read from controllers or access points that increase location accuracy: signal strength
of a client as heard by the AP of association, signal strength of a client as heard by APs other than the AP of
association, and signal strength at which an AP hears other APs.
These factors are detailed further in
Table 143
:
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 the office confines. See
“Adding Exterior Walls” on page
268
.
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
NOTE: These preferences are stored in the database, so they will be retained across browsers and machines.
NOTE: The remaining sections in this chapter apply to networks, campuses, buildings, and floor plans that have already been set
up in VisualRF. If you do not yet have any of this information in VisualRF for your network, refer to
“Planning and Provisioning” on
