Datasheet
The Ruckus MediaFlex adapter is the first Wi-Fi adapter with integrated
smart-MIMO antenna technology developed to reliably receive IP-based multimedia
content throughout the home.
One of the most sensitive Wi-Fi receivers on the market, the Ruckus MediaFlex
adapter is ideal for providing reliable Wi-Fi connectivity to Ethernet-equipped
media devices such as settop boxes, personal video recorders, media centers and
media center extenders. Compatible with standard 802.11b/g access points (AP)
that support WDS 4-address format bridging, the Ruckus MediaFlex adapter
802.11b/g adapter provides unprecedented range and reliability, effectively
eliminating Wi-Fi dead spots and hard-to-reach locations.

When used (but not required) with the Ruckus MediaFlex multimedia AP/router,
the Ruckus MediaFlex adapter constantly tunes the signal path to enable the most
stable and reliable Wi-Fi connectivity possible. This maximizes range and
assures uninterrupted bandwidth for whole-home multimedia transmissions.
Service providers can deploy the Ruckus MediaFlex adapter in subscribers’
homes to deliver broadcast quality, IP-based video applications, such as IPTV
and IPVoD (Video on Demand), without truck rolls for wiring installations.
Introducing the Ruckus MediaFlex adapter
The Ruckus MediaFlex adapter is the
first smart-MIMO wireless Ethernet adapter that provides video-grade, 802.11b/g
connectivity to any Ethernet-equipped media appliance such as a video server,
video receiver, cable set top box, personal video recorder, media center, or a
media center extender. Unlike any other Wi-Fi adapter on the market, the Ruckus
MediaFlex adapter automatically avoids Wi-Fi interference and mitigates
multipath fading by selecting the best signal path to the wireless AP.
One the most sensitive Wi-Fi receivers available, the Ruckus MediaFlex
adapter is ideal for use with the Ruckus MediaFlex router to ensure the most
consistent and reliable signal quality. Together, they enable broadcast quality,
wireless IPTV distribution despite the existence of physical obstructions.
Simple to provision, the Ruckus MediaFlex adapter allows IP-capable set-top
boxes to be located anywhere in the home without wiring concerns.

Both the Ruckus MediaFlex adapter and MediaFlex router integrate.
patent-pending BeamFlex smart antenna technology that constantly adapts to the
changing RF environment and automatically adjusts the antenna pattern to steer
signals to the optimum path. This provides the strongest protection against
degrading RF conditions.
BeamFlex Increases Range/Performance
BeamFlex is the first-of-it’s kind
smart antenna technology that works with off-the-shelf 802.11 silicon to deliver
the most cost-effective MIMO benefits to 802.11a/b/g devices today.

Each Ruckus MediaFlex adapter integrates Ruckus BeamFlex technology - a
compact, internal antenna array with six high-gain, directional antenna elements
capable of combining to form 63 unique antenna patterns for massive 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 while minimizing retransmissions.
Integrated with the 802.11 software driver, the BeamFlex control software
provides automatic antenna reconfiguration, data rate and transmission
management. It consumes minimal incremental processing cycles and memory
footprint.
Flexible Deployment Options
Deployed with the Ruckus MediaFlex router, the Ruckus MediaFlex adapter
enables the highest possible performance and best quality user experience. The
MediaFlex adapter can also be deployed without the MediaFlex router on the
client-side to mitigate interference and maximize signal quality.
Multiple client devices can be supported by a single MediaFlex adapter. The
Ruckus MediaFlex adapter can be attached to a switch or hub, providing reliable
and simultaneous connectivity to multiple devices.
Automatic Interference Avoidance
Unlike conventional
wireless devices, BeamFlex in the Ruckus MediaFlex adapter automatically
mitigates interference caused by multipath fading, neighbor networks and other
wireless devices. A sophisticated interference avoidance algorithm enables the
Ruckus MediaFlex adapter to detect the direction of interference from, for
example, a neighboring network, a microwave oven or a nearby blue tooth device.
In response, the Ruckus MediaFlex adapter is able to select antenna patterns
that direct energy away from the direction of interference; thereby attenuating
noise.
