Westlake Village, Calif.–April 17, 2007–Xirrus, Inc., the only provider of high-performance, long-range Wi-Fi products, announced today verification by The Tolly Group that demonstrates only five Xirrus Wi-Fi Arrays are needed to cover a one square mile area–greatly simplifying installation and lowering deployment costs for campus-wide Wi-Fi networks by reducing the number of devices required. By comparison, competitive solutions typically require 20 or more devices to cover the same area.

This exceptional outdoor Wi-Fi range, together with the high capacity, multi-radio architecture of the Xirrus Array, enables high-demand applications such as video-over-Wi-Fi while still greatly reducing costs. Xirrus recently announced that Charleston Southern University selected its Wi-Fi Arrays for the first-ever all-wireless video and audio streaming of NCAA events.

Engineers from The Tolly Group, an independent testing and strategic consulting organization, deployed a set of five Xirrus XS-3900 Wi-Fi Arrays to evaluate the real-world outdoor coverage and performance metrics using standard 802.11a/b/g notebook computer clients.

The Tolly Group test highlights concluded that Xirrus´ Wi-Fi Array:

*Provides more than a full square mile of wireless coverage area using a total of five XS-3900 Wi-Fi Arrays

*Offers up to a 36Mbps data rate connection from a distance of 1,500 feet between the Wi-Fi Array and a wireless notebook computer

*Creates an all-wireless Fast Ethernet-speed backbone by bonding multiple radios together, enabling applications such as video to be delivered over Wi-Fi

"Given the costs associated with procuring and installing outdoor access points, solutions that increase both transmission rate and signal range can provide significant value for campuses by decreasing the amount of access points and cabling required," said Dirk Gates, CEO of Xirrus. "The long range and high performance characteristics of the Wi-Fi Array make it an ideal solution for deploying new wireless applications like outdoor video surveillance systems in locations where provisioning a wired backhaul is difficult or cost prohibitive."

"Our test results highlighted that Xirrus harnesses the power of its multi-radio, multi-antenna solution to create a wireless backbone transparent to applications," said Kevin Tolly, president, CEO and founder of The Tolly Group. "Xirrus delivers the equivalent of a wired link aggregation in an easy to deploy, cost-effective solution."

Xirrus Wi-Fi Arrays provide superior wireless backhaul capabilities allowing up to 16 of its Integrated Access Points (IAPs) to form independent or bonded backhaul links that create either point-to-point or point-to-multi-point Wi-Fi connections between Arrays. Compared to competitive solutions that require backhaul radios to time share between servicing clients and performing backhaul functions, downstream throughput tests conducted by The Tolly Group illustrated that even at a distance of 1,700 feet (almost 1/3 mile), a standard Wi-Fi notebook computer still received 1 Mbps of throughput–nearly the throughput of a dedicated T1 circuit.
