Wi-Fi Array
Introduction 15
Non-Overlapping Channels
Complete use of non-overlapping channels limits interference and delivers
maximum capacity. On the XN16, up to 16 non-overlapping channels are fully
utilized across the 5GHz and 2.4GHz spectrums (up to 12 across the 5GHz
spectrum plus up to 3 across the 2.4 GHz spectrum—typically, one additional
radio is used as a dedicated RF monitor).
Secure Wireless Access
Multiple layers of authentication and encryption ensure secure data
transmissions. The Wi-Fi Array is 802.11i compliant with encryption support for
40 bit and 128 bit WEP, WPA and WPA2 with TKIP and AES encryption.
Authentication support is provided via 802.1x, including PEAP, EAP-TLS, EAP-
TTLS, and LEAP (Lightweight Extensible Authentication Protocol) passthrough.
Applications Enablement
QoS (Quality of Service) functionality combined with true switch capabilities
enable high density video and Voice over Wireless LAN deployments. Compliant
with 802.1p and 802.1Q standards.
SDMA Optimization
SDMA (Spatial Division Multiple Access) technology provides full 360° coverage
while allowing independent channel and power output customization. Also
supports fast inter-zone handoffs for time-sensitive applications and roaming
support.
Fast Roaming
Utilizes the Xirrus Roaming Protocol (XRP) ensuring fast and seamless roaming
capabilities between IAPs or Arrays at both Layer 2 and Layer 3.
Easy Deployment
The Xirrus Management System (XMS) offers real time monitoring and
management capabilities of the wireless network—ideal for the Enterprise
market. It also allows you to import floor plans to help you plan your
deployment. The Xirrus Wi-Fi Array chassis has a plenum rated, lockable and
tamper resistant case.
