Way back in the day, when powercode had the old type queue, we built
our basic one to buffer at 512 long enough to maintain a 2 hour sd
stream at 256k with periodic 512k bucket refills. so really it was
512k effectively. It may very vell be that expectations of "standard"
definition were different back then. but I thought that was an actual
resolution standard

I don’t remember ever being able to stream Netflix on 256K. 1M
maybe, and 1.5M still gives you decent SD. You’re going to need
at least 2.5M though for HD. So that’s one part of the answer is
HD. Some streaming services, like DirecTV On Demand, don’t have
adaptive video quality and want a minimum of 5M to stream.
Another factor is “live” video, which is compressed on-the-fly and
probably not as efficiently as pre-recorded content.
Of course, if the customer has more, video streams will happily
use it.

*Subject:* Re: [AFMUG] The Future
we are at the end of the wireless backhaul road. when I started 15
or so years ago, we were just moving off a handdful of random T1s
to a bonded 6mb circuit backhauling that was nothing. Now we have
two gig circuits on separate parts of our network, and we are a
tiny WISP in podunk USA.. We dont put less than 1.2gbps backhauls
in for core backhauls now. The existing technology for distance in
a single unit us roughly 2gbps when trying to cover any distance
of merit. Sure you can do more than that, you can cheat outside
link budgets and ignore your rain region. But if youre talking
about most temperate region backhauls with legitimate reliability
thats the wall.
we keep poking a little more bits/hz out, but that not really new
tech, its all dependent upon smaller and smaller path budgets,
that eventually wont be attainable. so you have to start doing
shorter shots, with more radios, more channel size, etc.
eventually you hit the point where its no longer economically
viable to keep throwing radio and lease costs at it and youll have
to put glass in the dirt.
Duct is whats future proof, fiber is just the current best long
term option for transport. pending some breakthrough tech, its the
only real long term cost effective future proofish option.
We will hit a wall on demand at some point in the near term as we
run out of things to connect.
Can anybody answer why 256k used to be able to deliver a decent SD
netflix stream and now i need multiple mbps for the same thing?

This isn't really true. There was one primary driver.
1) You need to bring down the cost of launch considerably in
order to expand the launch market to a size where developing
and maintaining a reusable rocket fleet makes sense but you
can't bring down the cost of launch till you have customers to
fill the launch manifest and that spool up will take years.
SpaceX thinks they have solved this by becoming their own
customer for all their extra launch capacity for the
foreseeable future.
When they looked at #1 above they realized that there was a
huge potential market there and even a a few % of the global
internet market could be a cash cow for years to come.

Guys, lots of misinformation here.
They are NO plans nor hints of integrating
Starlink antennas into Tesla cars. It may
happen but no one has hinted of this
happening. All Tesla's have 3G or 4G modems
already built-in to them along with WiFi.
Updates are sent via WiFi first and after the
fleet has received the updates, they
eventually push it to cars via cellular data
that haven't updated via WiFi.
Regarding B2B backhaul, I don't believe you'll
see this as an option anytime soon for WISP's
or other ISP's. They're targeting residential
and small businesses as well as
government contracts. The cost if they did
offer B2B backhaul services would likely be
higher than fiber to your network. Please stop
thinking this will happen as I bet it will not.
They may offer a self install option but
they'll also have a contractor to perform most
installs for a cost is my guess. Maybe they'll
send a self install kit for X price and if you
can't get it working, they'll schedule a
contract install for XX price.
I'll also say that you should not doubt Elon's
passion to achieve great things. I have a
Tesla and it's a work of art and by far the
best vehicle I've ever driven. 99% of people
who have driven one also think this. Tesla is
succeeding, SpaceX is on it's way there, The
Boring Company is half done with their Vegas
tunnel, and Starlink will likely be a viable
competitor for us.
