The Wi-Fi Array (regardless of the product model) is Wi-Fi® compliant and
simultaneously supports 802.11a, 802.11b and 802.11g clients. XR and XN model
arrays add the enhanced abilities of 802.11n to this combination. Active 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),
12 IAPs (XN12), 8 IAPs (XR4820, XR4830, XN8, XS8), and 4 IAPs (XR4420,
XR4430, XN4, XS4).

user authentication — multiple Arrays can authenticate to the optional XMS,
ensuring only authorized Arrays become part of the wireless network. With the
