Getting The Most—And The Best—From 802.11n.
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 also extracts the most out of the standards through a novel approach to channel selection called ChannelFly. ChannelFly moves all clients to the best ‘learned’ channel in real time instead of using traditional background scanning technologies which opens up the chance of lost data. ChannelFly increases capacity by up to 50 percent.
With Ruckus technology, 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.
