Trying to do all of what is currently wanted with 1 AP in a house is a huge
part of the current problems with WiFi networks.  MOAR power to try to
overcome attenuation and reflections from walls so more power bleeds into
the next home/suite/apartment etc.

In the MSP space it's been rapidly moving to an AP per room with output
turned down to minimum.    Doing this we can reused 5Ghz channels 50ft away
(through 2 walls etc...) without interference.

One issue with the RRH model is that to accomplish this 'light bulb' model,
ie you put a light bulb in the room you want light, is that it requires
infrastructure cabling.  1 RRH AP in a house is already a failure today and
accounts for most access complaints.

Mesh radios have provided a bit of a gap fill, getting the access SSID
closer to the device and backhauling on a separate channel with better (and
likely fixed position ) antennas.

regardless of my opinion on the full on failure of moving firewall off prem
and the associated security risks and liabilities, single AP in a home is
already a proven failure that has given rise to the mesh systems that are
top sellers and top performers today.

IMO, there was a scheme that gained a moment of fame and then died out of
powerline networking and an AP per room off that powerline network.  I have
some of these deployed with mikrotik PLA adapters and the model works
fantastically, but the powerline networking has evolved slowly so I'm
seeing ~200Mbps practical speeds, and the mikrotik units have 802.11n
radios in them so also a bit of a struggle for modern speeds.   This model,
with some development to get ~2.5Gbps practical speeds, and WiFi6 or WiFi7
per room at very low output power, is a very practical and deployable by
consumers setup.

WiFi7 also solves some pieces of this with AP coordination and
co-transmission, sort of like a MUMIMO with multiple APs, and that's in
early devices already (TPLINK just launched an AP).

IMO, too many hurdles for RRH models from massive amounts of unfrastructure
to build, homes and appartment buildings that need re-wired, security and
liability concerns of homes and business not being firewall isolated by
stakeholders of those networks.
