Either way, I think the question is how does it differentiate the chains from each other? Whether it's 4, 8, or 16, it's still multiple signals on the same channel at the same time. What's the idiot's version of how that works?

Massive MIMO in mobile and fixed wireless is a different story, big gains there. We routinely got 2-3x mu-mimo gain with 450M. 16x16 mu-mimo in wifi might be useful for something like a stadium or other wide open space with dense clients, but not much else IMO.

I've seen designs up to 64 with 32 2x2 streams. Massive MIMO is a good strategy.

Pretty much every client device is still going to be 2x2, or maybe you could call it 4x4 if running MLO in two bands.

Can someone explain to me the mechanism for using 16 spatial streams in a typical WiFi environment? I have a hard time wrapping my head around anything more than 2 using V/H or dual slant polarization. I was willing to believe that maybe you could get more (like maybe 4 spatial streams) due to reflections off furniture and stuff, and that somehow signal processing could magically separate out the streams (even though I don’t understand how it does that). But 8 or 16 just sounds like crazy talk. Maybe it’s like the rich people houses with 16 car garages, if I were rich people I would understand? -- AF mailing list [email protected]<mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected]<mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected]<mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
