Wireless Array
6 Introduction
XR-600 Series Access Points
These Access Points provide robust wireless service in low-to-medium user
density scenarios. These Access Points have two Gigabit Ethernet ports and two
multi-state radios (2.4GHz or 5GHz), so that as more of your clients migrate to
802.11ac, you can increase the number of radios operating at 5 GHz. Each of the
XR-630’s two 3x3 802.11ac radios supports 1.3Gbps, connecting up to 240 users at
one time with 2.6Gbps total Wi-Fi bandwidth.
These models have an integrated controller, firewall, threat sensor spectrum
analyzer, and application-level intelligence. These models have omni-directional
antennas rather than directional antennas.
The XR-630 supports a unique feature that optimizes wireless performance by
automatically segmenting faster 802.11ac clients from slower Wi-Fi clients. Since
Wi-Fi is a shared medium, this separation ensures slower 802.11a/b/g/n clients
do not slow down 802.11ac clients from achieving high performance.

Some smaller Arrays/APs have less memory (XR-500/1000 Series and
XR-620) and are not able to run all ArrayOS features at the same time. You
will receive an error message if you attempt to configure a feature when there
is not enough memory left.
