  Because
802.11n significantly increases top line bandwidth, it has
been touted as a cure-all for high-performance streaming
applications. Unfortunately, 802.11n technology is just as
susceptible to interference as 802.11b/g, and in some cases,
even more so. As a result, the actual throughput rates are
orders of magnitude lower than the data rates being
advertised.
To successfully apply 802.11n to high bandwidth enterprise
applications such as video conferencing, medical image
sharing, interactive learning, and IPTV, there's really only
one place to turn: Ruckus Wireless technology.
Why Ruckus? Because 802.11n uses "spatial multiplexing" to
combine two beams of data at the receiving end,
theoretically doubling throughput—but also doubling the
chances of interference. But Ruckus BeamFlex Smart antenna
technology mitigates interference by sending WiFi energy
only in the intended direction, thereby greatly increasing
the range of successful spatial multiplexing.
In addition, Ruckus improves 802.11n's "channel bonding"
techniques, which combine two 20Mhz channels into a
single-wide 40Mhz channel, for increased throughput. With
BeamFlex, channel bonding effectiveness is increased
four-fold.
Ruckus technology helps guarantee that 802.11n parameters
for beamforming and channel selection are dynamically tuned
for optimal throughput. With Ruckus, an 802.11n Wi-Fi AP can
reliably support up to six or more simultaneous,
flicker-free, 10Mbps streams of high-definition MPEG4 video.
And it can provide capacity for web browsing, email, and
Wi-Fi VoIP phones.
