Array Architecture

The Xirrus Wi-Fi Array represents the next generation in Wi-Fi architectures - integrating up to 16 Wi-Fi radios with an onboard Wi-Fi controller, Gigabit Switch, Firewall, Spectrum Analyzer, and a dedicated Wi-Fi Threat Sensor into a single device.

Multiple radios are co-located in a circular configuration to create a radio "Array" that provides significant range, capacity, and RF management advantages. Each Integrated Access Point (IAP) uses a high gain, directional Antenna System to deliver increased transmit gain and receive sensitivity in all directions, resulting in up to 4x the coverage area of traditional AP / Wi-Fi controller architectures.

By implementing the intelligence at the edge of the network, rather than in a centralized controller, the Xirrus Array improves network efficiency, lowers latency, improves network throughput, and simplifies network deployment.

The Xirrus 802.11n Array uses 3x3 MIMO technology to support data rates up to 300 Mbps per radio. The Array has three built in antennas per IAP integrating up to 60 antennas into a single device. The Arrays unique architecture provides an easy to install, aesthetically pleasing solution with no need for external cables or antennas.

11n Antennas

The Xirrus Wi-Fi Array delivers the most coverage, bandwidth, throughput, and support for more users on a per device and per system basis that 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.

Longer Range - Extended Coverage Area

Multi-radio, multi-sector antenna system creates a customizable 360º coverage pattern
Directional antennas provide increased transmit gain and greater receive sensitivity to increase range
Provides 2X the range and 4X the coverage area, enabling greater data rates at a given range

Superior Wi-Fi Performance

Delivers up to 4.8Gbps of RF bandwidth to provide up to 8x the capacity of devices used in current Wi-Fi deployments
Embedded Array Controller features multi-gigabit switching fabric and provides unprecedented coordination of the RF spectrum, security and Quality of Service (QoS) functions across the Integrated Access Points

Structured Wi-Fi Management

Dynamic channel assignment and monitoring of interference optimizes spectrum usage
Each RF sector size can be independently controlled, creating an adaptive pattern of desired coverage or to limit RF "bleed" outside of a given area
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 data protection
Monitors the RF environment for rogue access points and other security threats by dedicating one 802.11a/b/g IAP as a full-time Wi-Fi Threat Sensor
Array maintains intrusion detection table for all detected APs, adhocs, and stations
Unauthorized AP can be blocked preventing network users from associating to rogue APs
Integrated Spectrum Analyzer helps identify interface and provide insight into network behavior
Integrates with Xirrus Defense Module application to provide a proactive Intrusion Detection / Intrusion Prevention System (IDS/IPS)
Interfaces with external RADIUS servers to ensure proper authentication and accounting of users - also includes an embedded RADIUS server to support smaller deployments
Physical security of the Array is provided through a Kensington locking mechanism
Authentication for newly deployed Arrays can be automated using the optional Xirrus Management System
Each Array ships in a secure mode with the RF interfaces disabled ensuring the system is completely secure from installation through start up
Dynamic VLANS enable the Array to dynamically assign wireless stations to VLANs specified by RADIUS policy settings
Stateful firewall protects wireless network from unauthorized traffic

Deployment Efficiency

Simplifies Wi-Fi deployments by reducing the number of devices to install, manage, and support an average of 75%
Modular design allows for the replacement of Integrated Access Points for future upgrades as new 802.11 standards become available
Xirrus Management System provides efficient central management for large Array deployments, automatically discovering, authenticating and configuring new Arrays as they join the network
Straightforward installation using the included ceiling mounting kit with template or using optional indoor and outdoor enclosures

Reliability

Multiple points of redundancy, including at the radio, uplink port, and Array levels
Adjacent RF sectors overlap to provide continual service in the unlikely event of an Integrated Access Point failure
Radio Assurance executes self-diagnosis to detect and correct many issues before they are detected by network users
Integrated self-test helps validate integrity of Array and isolates issues to simplify troubleshooting
Full Array failover available by configuring a secondary Array to be used in a "hot standby" mode
