Sergiu tells me there's a new Medusa in the pipeline with 26 chains
instead of 14 chains, and supporting up to 100mhz channel sizes, and
supporting the 5.8ghz to 7ghz. Current SM's only support up to 5.9ghz,
so it'll be an SM swap to take advantage of the higher channels.....and
there's supposed to be a SAS for opportunistic access to that band.
This is all a couple years down the road, but it's looking like there's
at least one more upgrade cycle possible.

They were doing the polarization angular twist thing that will give
you lots of channels per carrier but the antennas are weird, huge and
fussy. And you have to have a different weird huge antenna for each
chain.

That could happen, but I can't make bets on it.

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.

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.

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.
