Prairie Cardiovascular Dials in Aruba's Adaptive Radio Management to Provide Interference-Free Wireless Networking

ARM Operates Trouble-Free Where Legacy Single Channel System Was Plagued by Nearby Wi-Fi Networks

SUNNYVALE, CA--(Marketwire - March 10, 2008) - Aruba Networks, Inc. (NASDAQ: ARUN), a global leader in wireless LANs and secure unified mobility solutions, today announced that Prairie Cardiovascular Consultants has selected and deployed Aruba's adaptive wireless LAN and secure mobility solution at its Springfield, Illinois facility. With more than 42 board certified cardiologists and 28 clinic sites in Illinois, Prairie is a national leader in the innovation and development of new cardiac diagnostic and treatment procedures. The wireless LAN is considered business-critical infrastructure for the company, both for office and clinical operations. The clinic's legacy single channel network could not be made to run reliably due to interference from wireless LANs in nearby clinics. Aruba's Adaptive Radio Management (ARM) technology resolved the issue by dynamically and automatically optimizing network operation.

"For the past two years we were in a world of hurt with our single channel network because it could never find a single channel that was interference free throughout the clinic," said John Collins, Prairie Cardiovascular's CIO. "We turned to Aruba for a solution, and immediately on power-up Aruba's ARM technology found 96 nearby Wi-Fi networks and then automatically adjusted radio coverage throughout the clinic to avoid interference. Our business-critical networks need to run 24/7, regardless of factors that are outside of our control -- such as other wireless networks running next door or across the street. We have witnessed first hand how quickly and effectively ARM can identify and correct for interference, without any operator intervention, and as a result we now have a network that works all day, every day."

Aruba's unified mobility solutions deliver networks to users by integrating adaptive WLANs, identity-based security, remote access, and cellular-to-Wi-Fi solutions into a cohesive, high-performance system. ARM technology delivers follow-me connectivity by automating network set-up, survey, and maintenance tasks, and continuously optimizing network performance to support data, toll-quality voice, and streaming video applications. In addition, ARM reliably supports Intel Centrino, Apple Macintosh, and the broad array of wireless PC clients commonly used by employees and contractors, a capability not found in single-channel technologies.

"It is our objective to make the wireless LAN simple and trouble free to use, and we do that by using automation to free users from complex surveys, simplify network set-up, and optimize settings to accommodate dynamic RF environments," said Keerti Melkote, Aruba's co-founder and head of products and partnerships. "Prairie Cardiovascular is a perfect example of why adaptively managing radios on an area-by-area basis is essential for real-world environments. In the real-world clients are imperfect, interference is dynamic, antenna patterns are not fully controllable. ARM accommodates these eventualities, and Prairie Cardiovascular's network is a testament to how an imperfect environment can be tamed when the right technology is employed."
