Feature Sets , intrusion detection and prevention, site monitoring, and RF
spectrum analysis are performed in the background by the AP automatically.
Deployment Flexibility
Xirrus’ unique multi-radio architecture (on all APs except the XR-500 Series)
generates 360 degrees of sectored high-gain 802.11a/b/g/n coverage that
provides extended range and the highest possible data rates for a large volume of
clients. Each sector can be adjusted automatically or manually, creating a pattern
of wireless coverage perfectly tailored to individual customer needs. For example:
Figure 3. Wireless Coverage Patterns
Figure 3 depicts the following two scenarios:

Full pattern coverage
All radios are activated with coverage spanning 360 degrees. If within
range, clients will always receive coverage regardless of their geographic
position relative to the AP. Radios may be assigned to 2.4 GHz and/or 5.0
GHz bands in any desired pattern.

Partial pattern coverage
If desired, the Wireless AP can be deployed close to an exterior wall. In
this case, half of all available radios have been deactivated to prevent
redundant signals from “bleeding” beyond the site’s perimeter wall. This
configuration may also be used in those cases where you want to restrict
wireless coverage to selected areas of the building’s interior.
