High-Density Applications Powered by MU-MIMO Technology

802.11ac Wave 2 MU-MIMO (Multi-User, Multiple Input, Multiple Output) technology allows a Wave 2 AP to communicate with multiple clients at the same time – significantly increasing multi-user throughput and overall user experience.

Scalable Enterprise Wi-Fi Management

UniFiUniFi® is the revolutionary Wi-Fi system that combines enterprise performance, unlimited scalability, and a central management controller. The UniFi AC HD AP has a refined industrial design and can be easily installed using the included mounting hardware.

Easily accessible through any standard web browser, the UniFi Controller software is a powerful software engine ideal for high-density client deployments requiring low latency and high uptime performance.

Use the UniFi Controller software to quickly configure and administer an enterprise Wi-Fi network – no special training required. RF map and performance features, real-time status, automatic UAP device detection, and advanced security options are all seamlessly integrated.

Fast Roaming

All Ubiquiti 802.11ac products support fast roaming. Fast Roaming works on all existing APs (11n and 11ac), does not have the single-channel requirement of ZHO, and thus works well in even the most dense client environments. UniFi's Fast Roaming "feature" is an optimization done in the background that doesn't require client device support.

Save Money and Save Time

UniFi comes bundled with a non-dedicated software controller that can be deployed on an on-site PC, Mac, or Linux machine; in a private cloud; or using a public cloud service. You also have the option of deploying the compact UniFi Cloud Key with built-in software.

Powerful Hardware

The UniFi 802.11AC Dual-Radio APs feature the latest in Wi-Fi 802.11AC MIMO technology.

Intuitive UniFi Controller Software

Configure and manage your APs with the easy-to-learn user interface.


Unlimited scalability: build wireless networks as big or small as needed. Start with one (or upgrade to a three-pack) and expand to thousands while maintaining a single unified management system.

Initial 802.11ac Wave 1 SU-MIMO (Single-User, Multiple Input, Multiple Output) technology allows an earlier-generation AP, such as the UniFi AC Pro AP, to communicate with only one client at a time.

802.11ac Wave 2 MU-MIMO (Multi-User, Multiple Input, Multiple Output) technology allows a Wave 2 AP, such as the UniFi AC HD AP, to communicate with multiple clients at the same time – significantly increasing multi-user throughput and overall user experience.

5 client aggregate throughput

The following describes a 5-client scenario:

MU-MIMO Assuming the same conditions, a Wave 2 AP provides up to 75% improvement* overall over a Wave 1 AP. This improvement increases wireless performance and/or serves more clients at the same performance level.

4x4 Spatial Streams At any single time, a Wave 2 AP can communicate with the following MU-MIMO clients:

  • four 1x1 clients
  • two 2x2 clients
  • one 2x2 client and two 1x1 clients
  • one 3x3 client and one 1x1 client

A 4x4 Wave 2 AP delivers up to 33% greater performance* than a Wave 1 AP that is 3x3 in both radio bands.

Real-World Performance The UniFi AC HD AP is the first UniFi 802.11ac Wave 2 AP. Combining the performance increases from MU-MIMO technology and the use of 4x4 spatial streams, the UniFi AC HD AP delivers up to 125% greater performance* than a typical Wave 1 AP.

Client Compatibility For optimal performance, use MU-MIMO clients. SU-MIMO clients will also benefit and gain up to 10-20% greater performance when used with the UniFi AC HD AP.
