Xirrus XD4-240 Series



Thousands connecting at once? Xirrus XD (Extreme Density) Wi-Fi access points deliver extreme performance in high-density environments such as classrooms, auditoriums, libraries and training centers. Integrated with four 802.11ac radios with high-gain directional antennas, XD4 APs support four times more users while decreasing cost of ownership up to 50% versus 2-radio solutions.

Xirrus offers two XD4 models: 3×3 Wave 1 (1.3Gbps) and 4×4 Wave 2 (3.47Gbps) 802.11ac options. Custom-build the system that best meets your needs. Accessories such as deployments kits, enclosures, and mounting options make installation easy.

Xirrus XD4 APs are designed with a wireless controller, firewall, and threat sensor built directly into the device. This reduces equipment requirements by 75%. And the scalable design lets you more efficiently upgrade your network.

Choose between cloud-based or on-premise network management. Xirrus solutions offer tools that let IT administrators manage users, devices, applications, and traffic with complete visibility.

At a Glance

  • 4-radio all 802.11ac Wave2 AP delivers highest density
  • Supports four times more users
  • Reduces equipment deployed by 75%
  • Decreases total cost of ownership up to 50%



Xirrus Xtreme Density (XD) Wi-Fi delivers the highest density Wi-Fi available in the industry today. Xirrus XD4 is the only 4-radio all 802.11ac AP available in the market, supports four times more users, reduces the amount of equipment deployed by 75 percent and decreases total cost of ownership by up to 50 percent versus competing solutions.


The XD4 integrates four high speed 802.11ac capable radios and optimizes performance with automated RF configuration. The XD platform, paired with award-winning Xirrus XMS cloud or on-premise management system, delivers groundbreaking performance and simplicity.


TurboXpress, featured on all XD APs, allows administrators to configure every radio on the AP for high-speed 802.11ac operation, with the click of a mouse, providing an instant performance boost of up to 6x. Xirrus XD is the only solution in the industry that can add wireless capacity instantaneously without adding AP’s


Stream-line IT operations with the Xirrus Management System (XMS), hosted either in the cloud or on-premise. XD APs integrate a set of powerful network services to optimize performance and ensure enterprise-grade wireless reliability including:

  • acXpress: Separate high-speed 802.11ac from low-speed Wi-Fi clients to optimize performance for all clients and ensure the best user experience.
  • Application Control: Ensure predictable Wi-Fi traffic performance and enforce policies for business-critical applications through integrated application visibility and controls over 1400 applications directly in the AP


XD Wi-Fi integrates the controller function into every AP, reducing system costs and improving overall system reliability. With most traditional wireless solutions, a central controller oversees the operation and maintenance of tens to hundreds of APs at once. In these networks, a single controller failure will impact the operation of all connected APs and their users.


  • Cloud-managed Wi-Fi option with zero-touch provisioning
  • Integrated application control to ensure reliable Wi-Fi performance
  • Distributed intelligence with integrated controller for no single point of failure
  • Superior user experience with optimized RF controls
  • Simplified user access with EasyPass for guests, employees, and BYOD


The Xirrus XD4-130 (11ac Wave 1) and XD4-240 (11ac Wave 2), High Density Access Points are are the highest capacity Wi-Fi APs on the planet and deliver massive scalability to meet the demands of today’s mobile users. These High Density APs feature powerful multi-core integrated controller, application-level intelligence, automated provisioning, and optional cloud management. Xirrus High Density APs are ideal for providing robust wireless connectivity in areas of medium to high density such as 1:1 classrooms, lecture halls, meeting rooms, open floor office areas and for Internet of Things (IOT) sensor networks. These highly extensible APs easily integrate with 3rd party software through standards based JSON APIs and the XD4-240 with Bluetooth Low Energy (BLE) radio is built ready for advanced capabilities such as location services.
