XR-4000 – Ultra-High Density Performance

More users. More devices. More demand. It goes without saying, at some point you’ll need to expand and upgrade your network to increase capacity. The XR-4000 series of ultra-high density modular APs keeps performing as your needs grow. Our modular design provides 4 or 8 radios. Add or swap radios when it’s time to scale up.


Large, high-density environments like auditoriums, libraries, and convention centers must support thousands of Wi-Fi devices in one area. The XR-4000’s multi-radio design significantly reduces the amount of equipment needed to deploy a powerful network to these venues. When you need more area coverage or more capacity, simply snap in an additional radio.

Choose between cloud-based or on-premise management. Xirrus access points offer a comprehensive set of tools to manage users, devices, applications, and traffic with complete visibility. The modular design and advanced features reduce your network’s total cost of ownership, giving you price, performance, and scalability.


  • Upgrade without replacing access points
  • Cloud management ensures zero-touch deployment and application control
  • Distributed intelligence with integrated controller for no single point of failure
  • EasyPass technology simplifies user access for guests, employees and BYOD
  • Scalable design grows with you, plus it’s easy to add or reprogram radios


XR-4000 modular APs have 2 to 6 core processors and 2 to 8 radio platforms. This allows you to build a powerful network that can support an increasing number of users. Get the capacity you need to meet the high performance demands of 802.11ac Wave 1 and 2.


Xirrus High Density APs utilize a modular architecture to sustain multiple generations of technologies, including 802.11ac Wave 2. Since there’s no need to replace infrastructure, you’ll extend the life of your Wi-Fi network.


Many wireless networks use a separate controller for each AP in the system. If one fails, it affects all of the other APs as well. But not with Xirrus. Our High Density APs use an integrated controller with distributed intelligence so users get a more powerful and reliable experience.


XR-4000 APs use Deep Packet Inspection (DPI) technology. Control over 1,400 applications at the network’s edge by prioritizing, blocking, or throttling applications or groups of applications by type, time, or day. These strategic capabilities provide predictable network performance.


Get advanced RF optimization with automatic channel, band, and power level selection. XR-4000 APs reduce interference by recognizing various channels being used in adjacent dwellings or rooms. Then, they automatically switch to the best available channel to provide a superior user experience.


Xirrus EasyPass combines security and simplicity. Guests, visitors, and BYOD users get quick access to the Wi-Fi network. IT administrators get full visibility to track user activity and protect data. EasyPass integrates with Google’s application ecosystem so users can take advantage of secure single sign-on (SSO) to the local network
