Installing the Xirrus Array

Building materials can make all the difference. For example, solid metal
doors or aluminum wall studs may adversely effect wireless signals. Try
to position wireless client devices so that the signal passes through
drywall (between studs) or open doorways and not other materials.
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 (or 1 to 2 meters).
3.
If using multiple Arrays at the same location, we recommend
maintaining a distance of at least 100 feet between units.
