This seems like a puff piece for cable to continue to justify why they continue to offer abysmal uplink speeds instead of improving infrastructure.

It’s unsurprising that the uplink caps at 5mpbs, it’s a 50/5 connection; but the article just wants the reader to “take their word” that the video stream look good without also comparing other connections (the apps themselves might self regulate) or latency (the apps might employ more buffering on a slow connection)

This is literally a lobby group composed of legacy coaxial copper plant last mile operators with a vested interest in squeezing every last ROI dollar out of docsis3, so your statement is quite correct.

The South Park nipple rubbing cable tv operators but in real life.

Eh, I wouldn't call CableLabs a "lobby group" although this is 100% a puff piece justifying the continued use of DOCSIS. They do real R&D and certification, and are the ones who actually develop DOCSIS and other standards for cable.

DOCSIS 3 maxes out at 1000/200, so if they would just provide that instead of trying to claim a 5Mbps upload is "broadband".

Cable is a perfectly viable technology, with DOCSIS 3.1 and 4, for at least another decade, probably more. Their own lack of infrastructure investment is coming to bite them in the ass, fast.

For clarification: I work for an ISP/telco that manages legacy copper POTS/xDSL, cable, fiber and cellular networks. While we are actively expanding fiber from the backbone out and doing a lot of FTTH by now, cable is still a solid workhorse, but it takes an operator who actually cares about maintaining the infrastructure.

1000/200 per segment of course. So in a typical HFC network that can be shared between 40-400 homes.

If you try to squeeze in as many endpoints as possible, sure.

With a competently designed network, you wouldn't have anywhere near that many in a segment.

I'm on a 300/60 cable connection via my employer, and I have never had my connection test below 360/70. This is in an an area densely populated with apartment buildings, where cable is still the best option for most people, with some fiber rolling out.

I am however moving to a 100/100 fiber connection (plenty fast for my needs, with the faster upload speed), due to a change in employment that is not of my own choice. So I don't consider myself biased in favor of my current employer ;-)

60mbps upload on DOCSIS?? That's fancy. I feel like my 20mbps is luxurious, although it's laughable when you consider the fact that it's 800mbps down.
Re:Expanded testing of video conferencing bandwidth usage ov... by KozmoNau7 on Thursday April 01, 2021 @08:55AM (#26659843)
We support up to 1Gbps/100Mbps as a standard subscription on cable, with symmetrical connections available for an additional fee, except on 1Gbit, where the fastest upload available is 500Mbps.

Cable is alive and well, if properly maintained and upgraded.

Re:Expanded testing of video conferencing bandwidth usage ov... by jaywalk on Thursday April 01, 2021 @10:00AM (#26660599)
I'm guessing it's a relatively small network, considering what I know about DOCSIS and how much would have to be upgraded to support uploads like that.

It covers the majority of urban and suburban Denmark, plus a majority of exurbs, anywhere an "antenna association" used to or still exists today and almost every apartment building. They are connected with coax through either us or one of our competitors, and there's mandated open access to coax.

Does it stray into the biased bullshit category enough to deserve flagging?
Re:Expanded testing of video conferencing bandwidth usage ov... by vkdelta on Thursday April 01, 2021 @01:59AM (#26657093)
Yep, it looks like they are trying to justify 5 Mbps upstream can meet FCC “broadband” criteria. FCC has been asking for minimum of 100/100.

With a gigabit uplink, in my experience video quality is noticeably better on several popular services.
Re:Expanded testing of video conferencing bandwidth usage ov... by d00bianista on Thursday April 01, 2021 @01:37AM (#26656993)
That would most likely be because of low latency and jitter. The app is in essentially the environment it was developed in and does not have to put effort into correcting errors that itself cause pauses in the visible video, since it tries to hide the parts where artefacts appear.

Ten years back I was told America likes to zap quickly through tv-channels with all the artefacts involved while Asia preferred a slower and artefact-free experience. Analog and keyframeless digital codecs are faster but not so bandwidth efficient.

Re:Expanded testing of video conferencing bandwidth usage ov... by mfgs on Thursday April 01, 2021 @01:16AM (#26656894)
I'd be curious to know how much bandwidth it utilises when that much is available.
