Location APs must be placed away from large metal objects, such as elevator shafts, and closer to ceiling height in
order to minimize interference from human traffic.
The following three scenarios elaborate on these general guidelines. Each scenario shows an incorrect placement along
side a correct placement. The incorrect placement results in two locales appearing identical to the Location AP. The
correct placement moves the Location AP to create asymmetrical views of the two locales.
Scenario 1
Placing a Location AP in the middle of the border between Locale 1 and Locale 2 makes the two locales appear identical
to that Location AP. Moving the Location AP to an outside edge, as in the diagram on the right, removes this symmetry,
creating a distinct RF pattern for Locale 2.
Scenario 2
Placing 1 Location AP in the center of Locale 2 and another in the center of Locale 3 makes Locale 4 look like Locale 1.
Moving the Location APs to the positions indicated in the diagram on the right removes this symmetry, creating a
distinct RF pattern for Locale 4.
Note.
The location of existing Location APs may be set up in contradiction to the
recommendations here - for instance, highly symmetrical and in the center of Locales. Even
staggering by as little as 5 meters can be enough to avoid the kind of symmetry mentioned
in this section.
