Wireless Array
14 Introduction
EAP-SIM, EAP-GRC, and LEAP (Lightweight Extensible Authentication Protocol)
passthrough. Intrusion detection and prevention provide proactive monitoring of
the environment for threats.
Applications Enablement
The Wireless Array’s 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.
Advanced Feature Sets
The Wireless Array offers a family of powerful functionality packages, including
the RF Performance Manager (RPM), RF Security Manager (RSM), and RF
Analysis Manager (RAM). These packages are separately licensed for operation
on your Array.
Xirrus Advanced RF Performance Manager (RPM)
The Xirrus RPM optimizes the bandwidth usage and station performance of
802.11n wireless networks. Leveraging the multiple integrated access point
(multi-radio) design of the Xirrus Wireless Array, RPM manages the allocation of
wireless bandwidth to wireless stations across multiple RF channels. The result
maximizes overall network performance with superior flexibility and capacity.
Today's wireless infrastructure is faced with ever increasing numbers and
variations of wireless enabled clients, whether in the form of notebooks, netbooks,
smart phones, IP phones, printers, projectors, cameras, RFID tags, etc. The advent
of higher speed 802.11n wireless and its increased use of the 5GHz spectrum adds
to the number of variables today's wireless networks must accommodate.
Backwards compatibility with older clients is crucial, however their operation in a
wireless network can significantly hinder the performance of faster clients. As an
example, 802.11b wireless stations communicate more than 10 times slower than
802.11n stations.
With each of the Array’s multiple radios operating on a different channel, RPM
selects the ideal radio for each station. High-speed stations are grouped together
on radios with other high speed stations, while lower speed stations are combined
