All that is in the air will one day be on the wire, and that which is on
the wire will one day be in the air.

We are doing lots of fiber. :)
It takes time though.

That's what I'm seeing as well I guess. Can't get more SNR, can't
get more hertz.
The only path to improvement I see is really big beam forming array
with even more MU-MIMO chains. Cost will go up accordingly I think.
The alternate path would be millimeter wave with all the obvious
caveats. Not trying to be a doomsayer, but I'm seeing a wall in front
of me.

It's seems to me that it would require a pretty radical change for
fixed wireless to progress a whole lot beyond what it's currently
capable of. Maybe 6ghz being opened up will allow for using much
wider channels, and keep things interesting, but I don't see things
like MU-MIMO being more than an incremental improvement, like
practically everything over the past decade or so.
60ghz has the potential to be a true competitor to fiber, but that's
going to require a completely different network design than what
we're used to.

In 10 years it will be trending to niche market for home use. We
will have fiber to the farm so it is what it is.

Best to watch The Simpson’s for a glimpse into the future.
I’m pretty sure there’s time travel involved.
I think RF Design hasn’t evolved much. Simple N=1 reuse and
cell splits are the method that’s been used successfully for
decades. Going smaller isn’t innovative. MiMo is a big
leap however. Broader channels are the only way to deliver
huge bandwidth. Going higher and higher QAM doesn’t work
well for mobile handsets and the diminishing returns and
crazy timing necessary to maintain a high QAM other than a
lab are not practical. Small cells are UGLY. They’re also
close to the people and EMR is a concern to many. The FCC
has guidelines that I do trust but we’re not dealing with
sites that are 100’ tall and every 1/2 mile now. They’re on
just about every street corner. Most carriers are digging
up the streets to bring fiber to each of these poles. It’s
an expensive deployment. 802.11ax is the best innovation
I’ve seen and it is truly 5G more than anything else that’s
out there. 8x8 and 12x12 MiMo and color coded streams for
interference mitigation are a big difference maker.

*Subject: *[AFMUG] Wireless future
Any opinions on where wireless technology will evolve in the
next 5 years?
There's a compound annual growth in demand, and trying to
think about
how manufacturers will meet that going forward. I'm
assuming we can't
count on bigger channels or more spectrum. So what then?
More MU-MIMO
chains? Or is it going to have to be street level small
cells (60ghz
etc)? Or something else?
We're investing heavily in fiber, as I know a lot of you
are, but the
wireless customers aren't going to go away.
