I bring this up less because i have any plans (I never have plans.
Never have the time or capacity to know far enough ahead of time when
I WILL have time) or Money to do any of the projects I want, but
looking at the theoretical bandwidth limits vs range increase?

Look. I live Simi-Rural. Meaning not so far out that you have hundreds
of acres for cattle, or farms or whatever. Just an eight acre piece of
land that's more of a family hobby project than anything. And yet that
is still a fairly sizeable chunk of land so far as traditional wifi is
concerned.

Fine, HaLow isn't intended to be used for netflix, youtube, etc etc.
However you look at all those older protocols, or protocols inspired
by those older things (like gemini, or AIM'S OSCAR protocol, etc) and
suddenly that ISDN level of bandwidth is looking pretty roomy.

Sure it's intended for smart devices, and I genuinely do like that as
an option since I can check my phone or theoretically make a terminal
device out of a raspberry pi (i lack the skillset and have poor vision
so all the fiddly bits are a bit beyond me) to, say, check the status
of the hot wire for horses (otherwise you get horses destroying the
fence to get to the grass on the other side, or out of pure boredom,
or because they find it funny,) send commands to turn on/off the
shop/barn lights, check a sensor that's connected to the mailbox to
see when it was last opened, state of feed/water levels for animals,
etc.

I get that a lot of these things are already products and have been
for awhile (especially geared for large farms.) I just think something
more hobby scale and or something I could build out of maybe fifty
bucks worth of parts from your choice in vendor.

Back when Egypt's main internet lines were turned off I had this idea
of what amounted to personal servers that used sftp or some other
protocol for the sake of file sharing, that also had pages and info up
for browsing along with a personal message board, mailbox, etc. The
main reason I just... never put myself into any projects (aside from
lack of knowledge) was that wifi inherently has, from the standpoint
of anyone rural, very limited range, thus restricting any sort of mesh
to densely packed municipalities, which limits usefulness.

Maybe my thinking is too pie in the sky, or 'dude they literally MAKE
those stop being daft.' I dunno.

I just find the lower end of things interesting given how much wider
the net can be cast, especially since this has far better bandwidth
than LoRA (as far as i know. Feel free to correct.)

I just... both feel out of my depth, and like I should at least toss
my two bits into the ring to see if anyone's had similar notions.
