The asymmetrical aspect of cable will be here to stay. Fiber can do it because it was build on a different foundation.
Copper cable transmits data using electric signals in various frequencies. There are a batch of frequencies reserved for phone and TV. ALL of the tv programming is constantly streamed to your lines whether you have TV or not and whether you pay for it or not. It’s encrypted and is only decrypted by your cable boxes when your provider says they can decrypt it. The phone frequencies are reserved so you can make phone calls and still max out your download.
So what about the rest of the bandwidth? Well, way back in the early days of cable it was pretty much everyone for themselves. Every company did things its own way. That’s where DOCSIS came in. It’s a platform that allows modem manufacturers to make modems that will work on any cable network that supports Docsis. And the key part is that DOCSIS is always backwards compatible. The network upgrade to 3.1 did not break the old d2 devices.
When it was developed the download was extremely more necessary than the upload. You’d be sending small single line commands on upload and receiving entire files in download. So more frequencies went to download than upload. In a lab setting 1.0 could reach 40mbps down and 10 up. That’s not what was sold because real life isn’t a lab and there’s loss over large distances. Realistically most people got 10 mb down and upload wasn’t even listed.
Whats changed? Well today those same download and upload frequencies are still used. We’ve added more around them to deliver higher speeds. But we’ve also kept the same principles that people need more download than upload. Docsis 3.1 was released in 2013. We really didn’t start stressing over upload until Covid and work from home had us on zoom calls all day.
Docsis 4.0 is technically released but requires quite a bit of overhaul to work with existing networks. We pretty much need to do away with cable tv. That’s why many ISP’s are pushing IPTv. It removes the need for all that bandwidth devoted to just TV. If everyone in a region drops traditional cable for IPTv they can easily switch to d4. D4 does increase upload but does not make it symmetrical.
Your cable company does not decide their highest tier realistically. It’s the most that medium will offer. It’s gonna be a while too for d4 to be available everywhere. Everyone would need to drop traditional cable (which is honestly a nice move regardless) and people don’t upgrade plans very often. When I worked in tech support I would frequently deal with customers complaining about slow speeds while on plans from 2002.

I really wish symmetric broadband was standard. Having 500 down (as a homelabber especially) means nothing if you have only 25 up 😭

Same boat here with Comcast. I would gladly give up some of the 800Mbps download to increase the 12Mbps upload speed I’m getting.

800Mbps*
*with SPEEDBOOST! (We throttle lawl)

DOCSIS 4.0 makes that a reality. Your connection will reallocate your available bandwidth between upload and download dynamically as needed.

Homelabber here, stuck in Comcast hell with 10Mbps upload.
I wish I could afford to bring the local municipal fiber to my house, but to go like 2 city blocks with it would be tens of thousands of dollars. :(
I’m considering a local colocation/ datacenter to move my homelab to. But then it wouldn’t be a homelab anymore

maybe you could last mile it with microwave point to point?

Would need to convince a local business down there to support it, but it’s not a terrible idea.
But it is a terrible situation that this is the length people need to go to to work around Comcast / DOCSIS lopsided networking.

How much is Comcast charging you compared to the fiber? If I were in that position I would have decided differently (assuming I owned the property) as the difference for me peaked at $150/mo. Even more if I chose a slightly cheaper plan…and I have AT%T fiber, not municipal.

Spectrum? I’ve got the same plan. Sucks because I have trouble streaming my Plex server outside of my apartment. And when I work from home uploads take forever.

Was definitely a big factor in going from Comcast to ATT (symmetric)in my area. Although Comcast has gotten faster too.
