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:
l Signal strength of a client as heard by the AP of association
l Signal strength of a client as heard by APs other than the AP of association
l Signal strength at which an AP hears other APs.
These factors are detailed further in Table 153:
