Business Wire, May 31, 2007

Xirrus Also Announces Company Has Been Selected for a Third Time to Provide the Wi-Fi Network for Interop New York 2007

WESTLAKE VILLAGE, Calif. -- Xirrus, Inc., the only provider of high performance, long range Wi-Fi products, validates the vision that "the air is the network" with a successful Wi-Fi network deployment at Interop Las Vegas 2007. Xirrus needed only 12 of its award-winning Wi-Fi Arrays to provide coverage for the entire event. The Xirrus Wi-Fi network successfully supported voice, video and data applications for the 20,000 attendees, exhibitors and media personnel. The Interop deployment provides yet another real world example that high performance Wi-Fi exists today and can easily extend the wired network to the 'air' without compromise.

The statistics in the following table demonstrate that Xirrus delivers today what others only promise. No other Wi-Fi vendor in the industry can deliver more bandwidth, coverage, or support for more users per cable drop than Xirrus.

"Xirrus has a proven track record of delivering high performance Wi-Fi networks and we are pleased to see them do it again at Interop Las Vegas 2007," said Glenn Evans, Lead Engineer of InteropNet. "With the Xirrus solution, we were able to deliver a powerful Wi-Fi network for thousands of conference attendees using a fraction of the devices, cabling and man hours of other offerings used in past events."

"Providing Wi-Fi telephony for InteropNet was an exciting challenge considering the number of wireless LANs in operation, the huge coverage area and density of users," said Geri Mitchell-Brown, Polycom's director of technical business development. "Together with Xirrus and in one of our most hostile wireless deployments to date, we were able to provide high-quality mobile voice on our SpectraLink 8000 Series Wireless Telephones. Using the less-crowded 802.11a band on Xirrus Wi-Fi Arrays, our handsets delivered reliable service and excellent voice quality to the InteropNet team and our partners as well as allowed us to demonstrate this technology in real time to industry media and analysts."

Due to the success at Interop New York last year and Interop Las Vegas this year, Xirrus has been selected for a third time to provide a high performance Wi-Fi network for Interop New York 2007.
