Agreed, AQM is like an emergency brake. Go ahead and keep it but hope to
never need to use it.

Hi Bob,
I like your design sketch and the ideas behind it.

The 6G is a contiguous 1200MhZ. It has low power indoor (LPI) and very
low power (VLP) modes. The pluggable transceiver could be color coded
to a chanspec, then the four color map problem can be used by
installers per those chanspecs.

Maybe design this to be dual band from the start to avoid the up/down
"tdm" approach we currently use? Better yet go full duplex, which
might be an option if we get enough radios that not much
beamforming/MIMO is necessary? I obviously lack deep enough
understanf=dingwhether this makes any sense or is just buzzword bingo
from my side :)
There is no CTS with microwave "interference" The high-speed PHY rates
combined with low-density AP/STA ratios, ideally 1/1, decrease the
probability of time signal superpositions. The goal with wireless
isn't high densities but to unleash humans. A bunch of humans stuck in
a dog park isn't really being unleashed. It's the ability to move from
block to block so-to-speak. FiWi is cheaper than sidewalks, sanitation
systems, etc.
The goal now is very low latency. Higher phy rates can achieve that
and leave the medium free the vast most of the time and shut down the
RRH too. Engineering extra capacity by orders of magnitude is better
than AQM. This has been the case in data centers for decades.
Congestion? Add a zero (or multiple by 10)
I am weary of this kind of trust in continuous exponential growth...
at one point we reach a limit and will need to figure out how to deal
with congestion again, so why drop this capability on the way? The
nice thing about AQMs is if there is no queue build up these basically
do nothing... (might need some design changes to optimize an AQM to be
as cheap as possible for the uncontended case)...
Note: None of this is done. This is a 5-10 year project with zero
engineering resources assigned.

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.
