uap-ac-hd 802. 11ac wave 2mu-mimo (multi-user, multiple input, multiple output) technology allows a wave2 apmunicate with multiple clients at the same time - significantlyincreasing 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 wirelessperformance and/or serves more clients at the same performance level. . . 4x4 spatial streams at any single time, a wave 2 apmunicate with thefollowing mu-mimo clients: : four 1x1 clients, two 2x2 clients, one 2x2 client andtwo 1x1 clients, one 3x3 client andone 1x1 client. A 4x4 wave 2 apdelivers up to 33% greater performance than a wave 1 ap that is 3x3 in bothradio bands. . . Real-world performance the unifi ac hd ap is the first unifi 802. 11ac wave 2ap. Combining the performance increases from mu-mimo technology and the use of4x4 spatial streams, the unifi ac hd ap delivers up to 225% greaterperformance* than a typical wave 1 ap.
