Wireless Array
8 Introduction
XR-2000/2005 Series Arrays
These Arrays include models with one or two Gigabit Ethernet ports and two or
four multi-state radios (2.4GHz or 5GHz) that can support 300Mbps or 450Mbps,
connecting up to 960 users at one time.
The Xirrus XR-2000 Series Wireless Array is a four slot chassis available in a four
multi-state (2.4GHz or 5GHz) radio configuration supporting up to 1.8Gbps of
bandwidth. These models support a range of low to high-performance
applications, including offices, hospitals, campuses and classrooms, and hotels.
Like larger XR Arrays, these models integrate multi-state radios with high gain
directional antennas, an onboard multi-gigabit switch, controller, firewall, threat
sensor and spectrum analyzer on a modular chassis designed for extensibility.

Some smaller Arrays/APs have less memory (XR-500/1000 Series and
XR-620) and can’t run all ArrayOS features simultaneously. You will see an
error message if you configure a feature when there is not enough memory.
