Xirrus XD4-240 11ac Wave 2 High-Density Access Point

The Xirrus XD4-240 is one of the highest capacity WiFi 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 XD4-240 Key Features

  • 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 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.

Unparalleled Performance

When it comes to high-density Wi-Fi the XD4 can’t beat. Four integrated 802.11ac capable radios and automated RF configuration continually optimize performance. The XD platform automatically chooses the best available bands and power level without IT intervention. Plus, it customises client connectivity for the best performance based on each device’s capability for a true zero-touch experience.

Best ROI

All XD APs feature TurboXpress, which allows administrators to configure every radio on the AP for high-speed 802.11ac operation with just one click, boosting Wi-Fi performance up to six times. It’s the only industry solution that can add wireless capacity instantly without adding APs. TurboXpress also enables you to effortlessly address changing needs, protecting your investment.
