New Dell'Oro Report Reaffirms Aruba Networks' Top Two Position in 802.11n Enterprise Wireless LAN Market Share and Revenue

Aruba Remains Solidly in Second Place After Cisco

Aruba Networks, Inc. (NASDAQ: ARUN), a global leader in wireless LANs and secure mobility solutions, today announced that market research firm Dell'Oro Group has again ranked Aruba as the second largest enterprise 802.11n vendor in terms of both total revenue and unit shipments. Including both Aruba branded products and those produced by Aruba for private label customers, Aruba's total 802.11n revenue garnered a 15.5% worldwide market share, and its unit shipments almost a 15% market share, placing it second only to Cisco. The new Dell'Oro report, titled "First Quarter 2009 Wireless LAN Report," is available for purchase from Dell'Oro at www.delloro.com.

In total 802.11n revenue, including what is sold under both its own name and the names of its private label customers, Aruba remains firmly established in second place, leading its next closest competitor by more than 30%. In total 802.11n shipments the gap widens to almost 50%.

Aruba's massively scalable centralized 802.11n architecture delivers switch-like performance while lowering IT operating expenses by simplifying network set-up, expansion, and updates. Unlike single- and multi-channel architectures, Aruba's adaptive 802.11n wireless LANs optimize Wi-Fi performance in real-time. Adaptive Radio Management (ARM) technology uses infrastructure-based controls to manage how Wi-Fi clients interact, ensuring that 802.11n data, voice, and video applications have sufficient network resources to operate properly.

Acting on their own, Wi-Fi clients do not always work cooperatively with other clients, or select the optimal band, channel, and access point. These issues are exacerbated in environments like lecture halls and dormitories with high-bandwidth applications and densely packed clients. ARM has been demonstrated to increase 802.11n throughput by more than 200%, enabling more than 100 laptops to reliably display multi-media lectures delivered from a single access point.

"ARM Yourself to Increase Enterprise WLAN Data Capacity," a new white paper outlining the technical features of ARM, is also available on-line at http://bit.ly/wFj9n.

"The ease of use, high performance, and economics of Aruba's high speed 802.11n solutions are garnering critical acclaim and attracting hundreds of new customers every quarter," said Keerti Melkote, Aruba's co-founder and head of products and partnerships. "The breadth of new 802.11n projects -- at schools districts, leading universities, Global 2000 enterprises, and government agencies worldwide -- validates the merits of our technology, and highlights why Aruba's market share remains strong even in a challenging economy."
