There are some folk local to my office who often speak about

clear (and our enterprise wireless folk echo this, actually) is that
the cellular network technologies of 'today' are far better at
client/power/tower control and management.

So much so that for dense deployments it sounds, actually, better to
have 4G/LTE on the 'tower' and push that chipset into laptop/etc
things. This way you can better control client -> tower associations
and traffic patterns and power demands. This isn't something that is
easily doable in the current (before wifi5 I mean? I dont' really know
much about the wifi world beyond 802.11ac gear, sorry) wifi
deployments, and client experience suffers often because of these
problems. Things like:
  overloaded basestations
  chatty clients
  bw hog clients
  borked radio/client stacks

You mean like when we all thought ATM was the hottest thing and that
laptops would have it instead of Ethernet :-). It's kind of like the
argument between a PSTN engineer and IP engineer about which network is
better.

Practically, GSM data works because folk self-police; because there is
an artificial barrier called Data (as in $$, not as in bits). Release
that artificial dam, and watch GSM data crumble to its knees.


What if the world had the capability to offer solid 'cellular' at the
cost (free) of 'wifi' in a bunch of these places? if the 'cellular'
was offered by local businesses and perhaps not subject to the telco
capture problems? (costs to the client) I think that's the world the
folk in my local office were pushing for... it seemed nice :) but
getting enough 4g/5g vs wifi chipsets into the clients seemed like the
really sticky wicket :(

The problem with consumer solutions is that they need to designed,
implemented, built, sold and operated at scale.

Ethernet and wi-fi are a lot better at this than SDH and GSM, when it
comes to having these components running around in people's hands. I
mean, just look at the Internet.
