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 XG AP, to communicate with mulple clients
at the same me – signicantly increasing mul-user
throughput and overall user experience.
MU-MIMO Assuming the same condions, a Wave 2
radio provides up to 75% improvement
1
beyond a Wave 1
radio. 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 radio
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
Real-World Performance Combining twice the number
of 5 GHz radios and four mes the associaons per radio,
the UniFi XG AP delivers an order of magnitude more
performance
1
than a typical 802.11ac 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 XG AP.
¹ Actual performance values may vary depending on environmental and
installaon condions.

Applicaon Scenarios
For very high-density environments, such as a large
auditorium or concert hall containing numerous clients in
a relavely small space, we recommend the UniFi XG AP.
Wave 1 and Wave 2 APs oer 28 independent
(non-overlapping) channels: three for the 2.4 GHz band
and twenty-ve for 5 GHz, including DFS channels.
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 XG AP can support more
than triple the number of users
2
per radio than a typical
Wave 1 AP.
