Wi-Fi Array Product Overview
Part of the family of Xirrus products, the Wi-Fi Array is a high capacity, multi-
mode device designed for the Enterprise market, with twice the range and up to
eight times the capacity of competitive wireless products.

The Wi-Fi Array (regardless of the product model) is Wi-Fi® compliant and
simultaneously supports 802.11a, 802.11b and 802.11g clients. XN model arrays
add the enhanced abilities of 802.11n to this combination. Enterprise class features
such as VLAN support and multiple SSID capability enable robust network
compatibility and a high level of scalability and system control. The optional
Xirrus Management System (XMS) allows global management of hundreds of
Arrays from a central location.
Multiple versions of the Array with different numbers of Integrated Access Points
(IAPs) support a variety of deployment applications: 16 IAPs (XN16, XS16,
XS-3900), 12 IAPs (XN12, XS12), 8 IAPs (XN8, XS8, XS-3700), and 4 IAPs (XN4,
XS4, XS-3500).
Enterprise Class Security
The latest and most effective wireless encryption security standards, including
WPA (Wi-Fi Protected Access) and WPA2 with 802.11i AES (Advanced
Encryption Standard) are provided with the Wi-Fi 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. Rogue AP
