Xirrus Wireless Array consists of a Wi-Fi controller, access points, sector antenna system, and Wi-Fi threat sensor.

Xirrus, Inc is a Wi-Fi technology company based in Thousand Oaks, California, US, that designs and sells wireless networking equipment based on the IEEE standards 802.11a, 802.11b, 802.11g, 802.11n and 802.11ac. The company has been independently selling these products since 2005.

Xirrus currently manufactures multiple radios that combine a WLAN switch and APs into a single device which they call a Wi-Fi Array.[1] Each Array unit bundles the controller with 4, 8, 12, 16 or 24 access points, and a special sectored directional antenna, into a single package.[2] The company also produces a low-cost two-radio access point with omnidirectional antennas.

Xirrus provides wireless infrastructure for general enterprise, education, public venues, healthcare, retail, government, hospitality, and manufacturing. As of 2013 Xirrus has over 4000 customers, with products and services sold internationally.

In 2010 Xirrus was ranked number 9 in Wall Street Journal's Next Big Thing list of the Top 50 Venture-Backed companies[3] and jumped to the number 2 spot on the same list in 2011.[4] Xirrus again occupied the number 2 spot on the list in 2012.[5]


Xirrus was founded in 2004 by Dirk Gates, Patrick Parker, and Steve DeGennaro.[6]

The company began marketing the Wi-Fi Array products in early 2005.[7] In 2005 Xirrus sold Wireless Arrays that met the 802.11a/b/g network standard.

In late 2008 Xirrus presented a new access point module that meets 802.11n standards, and provides up to 300Mbit/s data rate per radio.[8] The cryptographic module Xirrus's 802.11a/b/g-compliant "Wi-Fi Arrays" received Federal Information Processing Standards (FIPS) 140-2 validation in 2008.[9]

In 2012 Xirrus became the exclusive wireless solution provider for Paul Hastings LLP, servicing 18 international offices.[10] Other notable customers include Ashford and St Peter's Hospitals NHS Foundation Trust, the largest acute care provider in the world,[11] and Liverpool F.C., Anfield.[12]

In 2010, the company was ranked as the second Fastest-Growing Private Company among Telecommunications Equipment Manufacturers with Three-Year Sales Growth of 3,213% in the annual Inc. 500.[13]

Xirrus has provided the wireless network coverage for trade shows such as the Interop trade conferences[14] in 2006,[15] 2007,[16] 2009, 2010, 2011, and 2012. In 2012 Xirrus deployed 200 802.11a/b/g+n Wireless Arrays at the Sands Expo and Convention Center,.[17] which, at 2.25 million square feet, is the second largest convention center in the world.

In October 2012, Xirrus was included in Business Insider's DIGITAL list of the 100 most valuable private tech companies.[18]

Xirrus was acquired by Riverbed Technology in April 2017.
