MediaFlex 2200 Series

High Performance 802.11g Smart Wi-Fi Bridge/Repeater

Introducing the Ruckus MediaFlex 2200 Series

The Ruckus MediaFlex 2200 Series is the fi rst smart-MIMO Wi-Fi
gateway that reliably extends metro Wi-Fi signals indoors. The Ruckus
MediaFlex 2200 Series is equipped with industry’s fi rst dual-polarized
antenna array to optimize communication with metro Wi-Fi nodes.
Additionally, an external RF antenna option works in concert with the
smart antenna array and Ruckus’ patented expert control software to
ensure the best antenna patterns and RF paths are selected for send-
ing and receiving traffi c.

The Ruckus MediaFlex 2200 Series automatically avoids Wi-Fi
interference and mitigates multipath fading by selecting the best
signal path to the metro Wi-Fi node. Traditional Wi-Fi systems are
equipped with a single vertically-oriented, omni-directional antenna
that becomes less effective when the multipath signal arrives out of
phase and cross polarized.

The Ruckus MediaFlex 2200 Series integrates patent-pending Ruckus
BeamFlex technology that constantly learns the RF environment and
automatically adjusts the antenna pattern to steer signals to the opti-
mum path. Just as the other Ruckus products (MediaFlex 2800 series
router and 2111 adapter), MediaFlex Bridge/Repeater substantially
increases both Wi-Fi performance and range.

The Ruckus MediaFlex 2200 Series seamlessly communicates
with metro Wi-Fi nodes by automatically associating with the best
outdoor node. This built-in intelligence delivers optimum connec-
tivity upon initial association. In the event of changes to the Wi-Fi
environment or adjustments to the outdoor metro mesh network
(e.g., changes to channel assignments), the MediaFlex 2200 Series
continually rescans the RF domain so the selection of the best metro
Wi-Fi node is maintained.

Dramatic Increases in Range and Performance

BeamFlex is the fi rst-of-its kind smart antenna technology that works
with off-the-shelf 802.11 silicon to deliver the most cost effective
MIMO benefi ts to 802.11a/b/g devices today. Each Ruckus MediaFlex
2200 Series integrates Ruckus BeamFlex

technology — a compact,

internal antenna array with multiple dual-polarized directional antenna
elements capable of combining to form unique antenna patterns for
diversity. BeamFlex expert system control software continuously ranks
the antenna patterns for each destination device using the feedback
mechanism built into the 802.11 MAC layer protocol. Cognizant of
the real time RF conditions, the direction and performance of the
communicating devices, network capacity and application types,
BeamFlex steers each packet to the optimum signal path, enabling
a Wi-Fi device to sustain high transmission speeds and minimize
retransmissions. Unlike conventional wireless devices, the Ruckus 2200
Series dynamically mitigates interference caused by multipath fading,
neighbor networks and other wireless devices.

A state-of-the-art smart antenna array controlled by
an expert software system integrates six high-gain
horizonally-polarized antenna elements and two
vertically-polarized antenna elements. This provides
a 7 dBi gain thereby delivering unprecedented
range extension and Wi-Fi signal reliability. The best
antenna elements are use at any given moment for
any given packet and any given client based on
changing environmental conditions.
