Wireless Array
18 Introduction
Power over Gigabit Ethernet (PoGE)
Why Choose the Xirrus Wireless Array?
Advanced Feature Sets
The Wireless Array offers a family of powerful functionality packages, including
the RF Performance Manager (RPM), RF Security Manager (RSM), RF Analysis
Manager (RAM), and Application Control. These four packages are separately
licensed for operation on your Array. RPM, RSM, and RAM are automatically
included as part of all XR Arrays. Application Control is an optional feature.
Xirrus Advanced RF Performance Manager (RPM)
The Xirrus RPM optimizes the bandwidth usage and station performance of
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 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
with other lower speed stations. This ensures optimal performance for high-speed
802.11ac stations without compromise.
The complete feature set of the RPM package includes:
WDS (Wireless Distribution System) for point-to-point communication
