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? asking for a friend

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.
