Side-By-Side Comparison Of Xirrus Wi-Fi Arrays

The Xirrus family of Wi-Fi Arrays provide an unparalleled level of capacity, range, coverage, and performance to the Enterprise. Now the ability to securely deliver voice, video and data (Triple Play) to large user populations is realized at reduced deployment and ownership costs.

The Xirrus Array represents the next generation in enterprise wireless LAN (WLAN) architecture – combining the functionality of a WLAN switch/controller and Integrated Access Points (IAPs) in a single device. The Array delivers Gigabit-class Wi-Fi bandwidth to an extended coverage area simplifying the wireless LAN setup, deployment and management.

Because the Xirrus Array connects to the existing Ethernet network and doesn't require a centralized WLAN switch or appliance to operate, a Xirrus deployment reduces the number of devices to install and manage greatly simplifying a Wi-Fi deployment.

Intelligent Spectrum Management
  • Dynamic channel assignment and monitoring of interference optimizes spectrum usage
  • Each RF Sector size can be controlled, creating an adaptive pattern of desired coverage or to limit RF “bleed” outside of a building
  • Load balances clients across the Integrated Access Points based on changing load conditions
Enterprise Grade Security
  • Supports the latest wireless encryption and authentication standards including IEEE 802.1x, WPA (Wi-Fi Protected Access) and IEEE 802.11i AES (Advanced Encryption Standard) for the protection of data
  • Monitors the RF environment for rogue access points and other security threats by dedicating one 802.11a/b/g IAP as a full-time RF WLAN sniffer
  • Interfaces with external RADIUS servers to ensure proper authentication and accounting of users – also includes an embedded RADIUS server to support smaller deployments
  • Each rray ships in a secure mode with the RF interfaces disabled ensuring the system is completely secure from installation through start up
  • Physical security of the Array is provided through a Kensington Locking mechanism
  • Authentication for newly deployed Arrays can be automated using the optional Xirrus Centralized Management System
Deployment Efficiency – Superior TCO
  • Simplifies Wi-Fi deployments by reducing the number of devices to install, manage and support
  • Modular design allows for the replacement of Integrated Access Points for future upgrades as new standards become available
  • Xirrus offers a Centralized Management System (XM-3300 / XA-3300) providing central management when large numbers of Arrays are used - automatically discovers, authenticates and configures new Arrays as they join the network making deployments quick, easy and secure
  • Installation is straightforward using the included Ceiling Mounting Kit and Template or using the Ceiling Enclosure
  • Features multiple points of redundancy including failover modes for the dual Gigabit uplink ports
  • Adjacent RF sectors and the internal omni-directional antenna provide proper RF overlap to continue service in the unlikely event of an Integrated Access Point failure
  • Complete Array failover is made possible by allowing a secondary Array to be used in a "hot standby" mode

The Integrated Access Points are co-located in a circular configuration and use a high gain, Multi-sector Antenna System to deliver increased directional transmit and receive gain in all directions yielding up to 4x the coverage area of traditional architectures.
