@ryanc or... just microcell the shit out of the house with cheap EoL enterprise gear...
real talk: For a single AP home, that guide is decent. example: The TX power of the AP takes a lot of learning and experience to get right if you don't know any better.

@kajer I mean, that's exactly what I did and you know that, lol.
But the guide does recommend multiple APs.

@ryanc All of the images of access points in that guide have the antennas parallel to each other. Those dipole antennas radiate in a roughly doughnut shape, with weaker signal in the cone shaped volumes of space extending above and below the ends of the vertically aligned antennas. There are two antennas, and they can be positioned, so that they can be angled at 90 degrees to each other, so the dead zones of each is covered by the signal of the other.
I ended up learning /way/ to much about antennas when I got into flying FPV quadcopters:

@NaomiElizabeth That makes total sense for FPV racing, but I'm not sure it's correct for a MIMO system in a building.
When I was doing WiFi installations professionally, I learned that the antennas should be parallel to cover the same area as much as possible. This avoided multiple problems including the "hidden node" problem. At the time, though, multiple antennas were for diversity, not MIMO.
Current sources online mostly advocate against parallel antenna placement, which I am skeptical of, but I am not an RF engineer.
Can an actual RF engineer chime in?

@NaomiElizabeth this datasheet pretty clearly states that it's best to de-correlate the antennas as much as possible, so it seems that my understanding was not correct for MIMO systems.
