Ruckus paves way for enhanced performance within crowded, noisy Wi-Fi environments

Uses Ruckus-patented BeamFlex adaptive antenna approach to select the best signal path for any given Wi-Fi transmission

By CBR Staff Writer

Ruckus Wireless has introduced ChannelFly, a new technology specifically developed to address the growing need to deliver more reliable Wi-Fi performance within noisy and crowded RF environments caused by the invasion of smart, Wi-Fi-only devices onto enterprise and service provider networks.

ChannelFly leverages Ruckus-patented adaptive antenna approach, BeamFlex that constantly learns and selects the best signal path for any given Wi-Fi transmission.

The new tool apply a statistical adaptive channel selection technique to automatically determine the best radio operating frequency (RF channel) to be used that will yield the highest client throughput.

Ruckus Wireless co-founder and chief technology officer Bill Kish said historical approaches to Wi-Fi channel selection use spectrum analysis or packet sniffing techniques to basically guess the impact of interference on Wi-Fi capacity.

"But with Wi-Fi, what an AP hears doesn’t necessarily determine capacity. We skip those needless and disruptive steps and just measure the wireless capacity directly," Kish said.

"ChannelFly was conceived to turn the traditional model on its head by using statistical analysis of real-time channel performance to discover the true capacity of any channel at any time."

ChannelFly is based on a predictive model that uses actual channel activity to learn what channels will yield the most capacity to provide the highest client speeds, said the company.

With this, it quickly avoids interference within congested and noisy environments while maintaining maximum network throughput.

ChannelFly assesses all available channels within the 2.4 and 5GHz bands, and operates automatically without any human intervention with the integration within every Ruckus ZoneFlex Smart Wi-Fi AP.

With ChannelFly, Ruckus APs can automatically self-tune before any client devices are connected thereby avoiding service disruptions that can often be associated with RF channel changes.
