Wireless LAN Array
Introduction 7
Deployment Flexibility
Xirrus’ unique multi-radio architecture generates 360 degrees of sectored high-
gain 802.11a/b/g coverage that provides extended range and the highest possible
data rates for a large volume of clients. Each sector can be controlled
automatically or manually, creating a pattern of wireless coverage perfectly
tailored to individual customer needs. For example:
Figure 3. Wireless Coverage Patterns
Figure 2 depicts the following two scenarios:
z 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 XS-3900.
z Partial pattern coverage
If desired, the XS-3900 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.
