802.11ac Technology
Inial 802.11ac Wave 1 SU-MIMO (Single-User,
Mulple Input, Mulple Output) technology allows an
earlier-generaon AP, such as the UniFi AC Pro AP, to
communicate with only one client at a me.
802.11ac Wave 2 MU-MIMO (Mul-User, Mulple Input,
Mulple Output) technology allows a Wave 2 AP, such as
the UniFi SHD AP, to communicate with mulple clients
at the same me – signicantly increasing mul-user
throughput and overall user experience.
The following describes a 5-client scenario:
MU-MIMO Assuming the same condions, a Wave 2 AP
provides up to 75% improvement
1
overall over a Wave 1
AP. This improvement increases wireless performance
and/or serves more clients at the same performance level.
4x4 Spaal Streams At any single me, 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 SHD AP is the
rst UniFi 802.11ac Wave 2 AP with a dedicated
security radio. Combining the performance increases
from MU-MIMO technology and the use of 4x4 spaal
streams, the UniFi SHD AP delivers up to 125% greater
performance
1
than a typical Wave 1 AP.
Client Compability For opmal performance, use
MU-MIMO clients. SU-MIMO clients will also benet and
gain up to 10-20% greater performance when used with
the UniFi SHD AP.
¹ Actual performance values may vary depending on environmental and
installaon condions.

High-Density Scenarios
For high-density environments, such as a concert venue or
outdoor fair where there are numerous clients in a relavely
small space, we recommend the UniFi SHD AP.
2.4 GHz versus 5 GHz Band
When you use the 2.4 GHz band in a high-density locaon,
you encounter self-interference and channel saturaon.
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
spaal streams, the UniFi SHD AP can support more than
triple the number of users
2
than a typical Wave 1 AP can.
