Wireless Array
Introduction 11
Enterprise Class Security
The latest and most effective wireless encryption security standards, including
WPA (Wireless Protected Access) and WPA2 with 802.11i AES (Advanced
Encryption Standard) are available on the Wireless Array. In addition, the use of
an embedded RADIUS server (or 802.1x with an external RADIUS server) ensures
user authentication — multiple Arrays can authenticate to the optional XMS,
ensuring only authorized Arrays become part of the wireless network. With the
Xirrus
Advanced Feature Sets , intrusion detection and prevention, site
monitoring, and RF spectrum analysis are performed in the background by the
Array automatically.
Deployment Flexibility
Xirrus’ unique multi-radio architecture (on all Arrays 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:

Full pattern coverage
All radios are activated with coverage spanning 360 degrees. If within
range, clients will always receive coverage regardless of their geographic
outside wall
