The Ubiquiti UniFi AC HD Access Points in high-density environments requiring maximum wireless performance. The UniFi AC HD AP features simultaneous dual-band, 4x4 MU-MIMO technology and convenient 802.3at PoE+ compatibility. The Wave 2 MU-MIMO technology allows the AP to communicate with multiple clients at the same time - significantly increasing multi-user throughput and overall user experience. The UniFi AC HD AP is the first UniFi 802.11ac Wave 2 AP. It combines the performance increases from MU-MIMO technology and the use of 4x4 spatial streams to deliver up to 125% greater performance than a typical Wave 1 AP.

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

• Four 1x1 clients
• Two 2x2 clients
• One 2x2 clients and two 1x1 clients
• One 3x3 clients and one 1x1 client

• Radio Hardware Acceleration: Independent 2.4GHz and 5GHz dedicated hardware offload for maximized multi-user throughput and reduced latency
• CPU Hardware Acceleration: Dedicated hardware offload for QoS, Guest Control, and Client Management
• Optimized for MU-MIMO: Genetically optimized antenna arrays for maximal utilization of 802.11ac Wave 2 MU-MIMO Beam Forming
• Beam Forming: Data is sent and received using multiple antennas to increase throughput and range
