High-Density Scenarios
For high-density environments, such as a concert venue or outdoor fair where there are numerous clients in a relatively small space, we recommend the UniFi HD AP.
Both Wave 1 and Wave 2 APs offer 28 independent (non-overlapping) channels: three for the 2.4 GHz band and twenty-five for the 5 GHz band, including DFS channels.
When you use the 2.4 GHz band in a high-density location, you encounter self-interference and channel saturation. When you use the 5 GHz band, you can deploy smaller cells (coverage areas), so you can support more clients in any cell that deploys more than one AP.
With the advantages of MU-MIMO technology and 4x4 spatial streams, the UniFi HD AP can support more than triple the number of users** than a typical Wave 1 AP.
802.11ac Technology
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 HD AP, to communicate with multiple clients at the same time – significantly increasing multi-user throughput and overall user experience.
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.
