Carnegie Mellon University Validates Production 802.11n Network

Xirrus, Inc., the Wi-Fi "Power-Play" that delivers the most coverage, bandwidth, and throughput in the industry, announces the move from beta to production status of the Xirrus 802.11abg+n Wi-Fi Arrays at Carnegie Mellon University, with more than 14,000 students, faculty, and staff able to access the new Xirrus Wi-Fi network.

"Over 2,800 Xirrus 802.11abg+n integrated access points are now operational using only 350 Xirrus Wi-Fi Arrays," said Dan McCarriar, Director of Network and Production Services at Carnegie Mellon University. "We chose Xirrus to be deployed in the most demanding areas of our campus, including the residence halls and buildings housing a variety of engineering and computer science programs, where performance needs continually spike and the types of applications and devices vary greatly."

Carnegie Mellon University's Wireless Andrew network was one of the first campus-wide wireless networks in the world and has been in operation since 1994. Today, Wireless Andrew 2.0 provides service to over 14,000 students, faculty, and staff across the university's main campus.

"Xirrus 802.11abg+n Wi-Fi Arrays have allowed us to take the next leap in performance that will carry us forward for the next 5 years," added McCarriar. "It's interesting to note that nearly 100% of this year's incoming freshmen who brought laptops had 802.11abg+n-capable wireless cards. We fully expect to see the total student population with 802.11n-capable notebooks climb to 50% next year. As the use of Xirrus 802.11n grows, we expect a reduction in use of wired network ports by end users, and even can foresee purchasing fewer 10/100 wired Ethernet switch ports during our next upgrade."

"Servicing 14,000 students would break traditional controller-based Wi-Fi architectures. The Xirrus Wi-Fi Array is unique compared to other solutions in that we place the power and intelligence closer to the user by integrating 4, 8, 12, 16, or 24 802.11abg+n radios in to a single device, coupled to a high-gain directional antenna system along with an onboard multi-gigabit switch, Wi-Fi controller, firewall, dedicated Wi-Fi threat sensor, and an embedded spectrum analyzer," said Dirk Gates, Co-founder and CEO at Xirrus. "Unlike other Wi-Fi vendors, we designed our architecture to replace the wired network - delivering far better coverage, bandwidth, and throughput than anything else available on the market today."

About Carnegie Mellon University

Carnegie Mellon is a private research university with a distinctive mix of programs in engineering, computer science, robotics, business, public policy, fine arts and the humanities. More than 10,000 undergraduate and graduate students receive an education characterized by its focus on creating and implementing solutions for real problems, interdisciplinary collaboration, and innovation. A small student-to-faculty ratio provides an opportunity for close interaction between students and professors. While technology is pervasive on its 144-acre Pittsburgh campus, Carnegie Mellon is also distinctive among leading research universities for the world-renowned programs in its College of Fine Arts. A global university, Carnegie Mellon has campuses in Silicon Valley, Calif., and Qatar, and programs in Asia, Australia and Europe. For more, please visit

About Xirrus

Xirrus, the only Wi-Fi "Power-Play," manufactures the Wi-Fi Array(R) architecture that displaces both overlay Wi-Fi offerings and switched Ethernet to the desktop. The Wi-Fi Array integrates 4, 8, 12, 16, or 24 802.11abg+n radios coupled to a high-gain directional antenna system into a single device along with an onboard multi-gigabit switch, Wi-Fi controller, firewall, dedicated Wi-Fi threat sensor, and an embedded spectrum analyzer. The Wi-Fi Array provides more than enough bandwidth, security, and control to replace switched Ethernet to the desktop as the primary network connection. The Xirrus Wi-Fi Array delivers the most coverage, bandwidth, throughput, and support for more users on a per device and per system basis than anything else available on the market today - resulting in a solution that uses 75% fewer devices, cabling, switch ports, power, space, and installation time compared with any other offering.

Xirrus is a privately-held company headquartered in Thousand Oaks, California. For more information, please visit
