Array Architecture
The Xirrus Wi-Fi Array represents the next generation in wireless LAN (WLAN) architectures – integrating up to 16 Wi-Fi radios with an onboard WLAN 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 / WLAN 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.
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 864Mbps of RF bandwidth to provide up to 8x the capacity of devices used in current Wi-Fi deployments
- Embedded Array Controller features a 2.1Gbps 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
- 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 standards such as 802.11n 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
- 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
- Active RF Watchdog monitors radio availability and validates network functionality
