Wireless Array
Introduction 15
Extended Coverage
One XR-7630 solution enables you to replace fifteen access points (including one
omnidirectional IAP for monitoring the network). Fifteen IAP radios with
integrated directional antennas provide increased wireless range and enhanced
data rates in all directions. With a Wireless Array deployed, far fewer access
points are needed and wired-like resiliency is delivered throughout your wireless
network. Your Wireless Array deployment ensures:
 Continuous connectivity if an IAP (radio) fails.
 Continuous connectivity if an Array fails.
 Continuous connectivity if a WDS link or switch fails.
 Continuous connectivity if a Gigabit uplink or switch fails.
Non-Overlapping Channels
Complete use of non-overlapping channels limits interference and delivers
maximum capacity. On the XR-7630, 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).
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.
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 for the wireless network — ideal for the Enterprise
market. It also allows you to import floor plans to help you plan your
deployment. The Xirrus Wireless Array chassis has a plenum rated, lockable and
tamper resistant case.
