My brother and I installed irrigation systems in Texas where it rains a
lot. No problem with getting business. Digging trenches, laying & gluing
PVC pipe, installing controller wires, etc is good, respectable work.
I wonder if too many white-collar workers avoided blue-collar work and
don't understand that blue-collar workers actually are very interested
in installing fiber (or Actifi) and being part of improving things.

I think the big problem with this is users per domicile. It's easy
enough to support one floor of a residence with a single AP. There is
an upper limit on the bandwidth that one user can ever require. It is
probably what is needed for full-sphere VR at the perceptual limit. We
have long achieved the perceptual limit of ears, on top of that we
have a lot of tweaking and self-deception. We will get to the limit of
eyes. Multiply this by eight users per domicile for a limit that most
would fit in. We can probably do that with one AP. The additional
equipment and maintenance outlay for structural fiber and an AP per
room doesn't really seem worth it.

I like the general idea, especially if there was a site-wide
controller module that can do the sort of frequency allocation that
network engineers do in dense AP deployments today: adjacent APs
run on different frequency bands so that they reduce the likelihood
of stepping on each others transmissions.
One of the biggest knowledge gaps that I see people have around
wireless is that it IS a shared medium. It both is, and isn’t a
bus. Shared like a bus, but with the hidden transmissions that
remove the csma abilities that get with a bus.
But the main issue will be deployment. This would be great for
commercial buildings that get retrofitted every decade or so with
new gear.
This will be near-impossible in the US except for new construction
or big remodels of existing structures. The cost of opening the
walls to run the fiber will make the cost of the hardware itself
insignificant.
OTOH, because the STAs aren’t specialized, the existing ones
“just work”, and so you don’t have the usual bootstrap issue
that plagues tech like zigbee and Zwave, where there isn’t enough
infra to justify the devices, or not enough devices to justify the
infra.

the AP needs to blast a CTS so every other possible conversation has

The wireless network is not a bus. This still ignores the hidden
transmitter problem because there is a similar network in the next
room.
