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 nanoHD AP, to communicate with multiple
clients at the same time – signicantly 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
1
overall over a Wave1
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
1
than a Wave 1 AP that is 3x3 in both radio bands.
Real-World Performance The UniFi nanoHD AP is the
UniFi 802.11ac Wave 2 AP with the smallest form factor.
Combining the performance increases from MU-MIMO
technology and the use of 4x4 spatial streams, the UniFi
nanoHD AP delivers up to 125% greater performance
1
than a typical Wave 1 AP.
Client Compatibility For optimal performance, use
MU‑MIMO clients. SU‑MIMO clients will also benet and
gain up to 10-20% greater performance when used with
the UniFi nanoHD AP.
¹ Actual performance values may vary depending on environmental and
installation conditions.

High-Density Scenarios
For high-density environments, such as a theater where
there are numerous clients in a relatively small space,
we recommend the UniFi nanoHD AP when a minimal
footprint is also required.
Both Wave 1 and Wave 2 APs offer 28 independent
(non-overlapping) channels: three for the 2.4 GHz band
and twenty‑ve 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 nanoHD AP can support more
than triple the number of users
2
than a typical Wave1 AP.
