Coverage and Capacity Planning
This section considers coverage and capacity for your deployment(s), including
placement options, RF patterns and cell sizes, area calculations, roaming
considerations, and channel allocations.
Placement
Use the following guidelines when considering placement options:
1. The best placement option for the Array is ceiling-mounted within an
open plan environment (cubicles rather than fixed walls).
2. Keep the Array away from electrical devices or appliances that generate
RF noise. Because the Array is generally mounted on ceilings, be aware of
its position relative to lighting (especially fluorescent lighting) — we
recommend maintaining a distance of at least 3 to 6 feet (1 to 2 meters).

Note that several advanced features in this section are part of the Xirrus
Advanced RF Performance Manager (RPM). They require the license
installed on the Array to include support for RPM. Please see “About
Licensing and Upgrades” on page 325.
