802.11AC Wave 2 MU-MIMO (Multi-User, Multiple Input, Multiple Output) technology allows a Wave 2 AP to communicate with multiple clients at the same time – significantly increasing multi-user throughput and overall user experience.
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.
4×4 Spatial Streams At any single time, a Wave 2 AP can communicate with the following MU-MIMO clients:
- four 1×1 clients
- two 2×2 clients
- one 2×2 client and two 1×1 clients
- one 3×3 client and one 1×1 client
A 4×4 Wave 2 AP delivers up to 33% greater performance than a Wave 1 AP that is 3×3 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 4×4 spatial streams, the UniFi AC HD AP delivers up to 225% greater performance* than a typical Wave 1 AP.
