22 Installing the XS-3900
RF Patterns
The XS-3900 allows you to control—automatically or manually—the pattern of
wireless coverage that best suits your deployment needs. You can choose to
operate with full coverage, half coverage, or custom coverage (by enabling or
disabling individual sectors).
Full (Normal) Coverage
In normal operation, the XS-3900 provides a full 360 degrees of coverage.
Figure 10. Full (Normal) Coverage
Half Coverage
If installing a unit close to an exterior wall, you can deactivate half of the radios to
prevent redundant signals from “bleeding” beyond the wall and extending
service into public areas. The same principle applies if you want to restrict service
to an adjacent room within the site.
