Wireless Leaders Unveil Plans to Collaborate on Advanced 802.11n Solutions That Address Growing Concerns over Performance Predictability, Security and Reliability. Ruckus Wireless and Aruba Networks today announced that they are collaborating on the development of advanced 802.11n products and technologies that help corporations, service providers and consumers safely migrate to the next generation of Wireless Fidelity (Wi-Fi).
Under the joint development, the companies are creating new high-speed 802.11n solutions that combine centralized control of wireless networks with essential capabilities not found in emerging pre-N products, such as smart antenna technology and dynamic RF optimization.
The new products will integrate innovative features such as dynamic signal path steering, interference avoidance and real-time optimization controls developed by Ruckus Wireless, with adaptive radio management (ARM) and wireless intrusion prevention (WIP) technologies developed by Aruba Networks. The combined solution will automatically select the best channel and power levels for 802.11n access points, detect 802.11n rogue access points and continuously mitigate interference by selecting the best signal path in real time based on the RF environment, receiving device and traffic type.
"When two industry leaders collaborate on next-generation technology, expectations are justifiably high," said Craig Mathias, principal research analyst at the Farpoint Group. "While we've got a ways to go before 802.11n is finished, it's not too early for enterprises to get it into their planning. I'm looking forward to seeing the benefits of combining the advances Ruckus Wireless has made in such demanding wireless applications as streaming video with the enterprise-class RF management capabilities for which Aruba is famous."
The Future of Wi-Fi with 802.11n
802.11n, the next step in Wi-Fi, is designed to significantly boost the capacity of wireless networks by more than quadrupling the speed of the current-day technology. While 802.11n will push Wi-Fi performance and scalability to new levels, neither the draft standard, nor the current Pre-N technology, is ready for production environments. Ruckus Wireless uniquely offers 100%, standards-compliant 802.11 extensions that have proven to deliver reliable range and performance in pervasive production networks around the world.
Today's Wi-Fi technology (802.11a/g) operates at a theoretical limit of 54 Mbps per second. 802.11n will operate at 200 Mbps or more by using multiple transmitters and receivers simultaneously. But this also increases the number of things that can go wrong with the integrity and security of the transmission. 802.11n will also permit doubling of the channel width to increase physical data rates. This, and the added transmit and receive radios, raises the potential for interference with nearby wireless devices. Therefore, the ability to dynamically control where Wi-Fi signals go, adjust the multitude of new parameters and tightly secure the RF environment is key to a robust 802.11n network. Ruckus Wireless and Aruba Networks will work to develop an application-focused control framework to address these difficult real-time optimization problems.
The new products, to be delivered immediately upon ratification of the 802.11n standard, are expected to be the first, centrally managed enterprise 802.11n solution that adds important wireless stability features necessary to ensure predictable performance. In addition, the companies agreed to enable Ruckus Wireless access points to be managed by Aruba's mobility controllers to support enterprise telecommuters and emerging managed WLAN services by service providers.
Aruba and Ruckus Wireless will also collaborate to solve the deployment and security challenges created by the new 802.11n wireless standard by optimizing the selection of 20MHz or 40MHz operational modes, burst modes and other capabilities that are introduced in the new standard. digy
"We are teaming with Ruckus Wireless because they are the experts in next-generation RF technology," said Keerti Melkote, co-founder and vice president of Marketing for Aruba Networks. "802.11n is too important to the enterprise to merely throw out into the market a complex and high-priced solution, especially one that doesn't address the important issues of signal reliability and interference mitigation. Ruckus has demonstrated that they can add tremendous value at the lowest cost with proven technology that solves all of these problems in a flexible manner."
"802.11n is strategically important to enterprises, service providers and consumers alike, but it must be delivered with real products that are reliable and dependable," said Selina Lo, Ruckus Wireless' CEO. "When the standard matures and is implemented everywhere, users will see more interference, not less. This collaboration with Aruba, clearly the most innovative enterprise WLAN vendor in the industry, will give us the expertise and distribution channels to solve these issues for enterprises and service providers."
Ruckus Wireless plans to extend its patent-pending BeamFlex technology to 802.11n, making it available by the end of 2006. BeamFlex-N is expected to be capable of supporting three or more simultaneous high definition (HDTV) video streams.
