On coax/cable lines like Charter/Spectrum, the upload speed limit is due to protocol/DOCSIS limitations. Supposedly the new version of DOCSIS fixes this/allows for symmetrical service, and Spectrum has been rolling it out for a while now. Still waiting for it where I'm at...
- m463 3y agoI've seen this explanation, but it makes no sense ver year download upload 1.0 1997 40 Mbit/s 10 Mbit/s 1.1 2001 40 Mbit/s 10 Mbit/s 2.0 2002 40 Mbit/s 30 Mbit/s 3.0 2006 1 Gbit/s 200 Mbit/s 3.1 2013 10 Gbit/s 1–2 Gbit/s 4.0 2017 10 Gbit/s 6 Gbit/s the version previous to the "new version" uploads at 1-2gbit/s which is 40-80x the FCC value https://en.wikipedia.org/wiki/DOCSIS#Comparison https://en.wikipedia.org/wiki/DOCSIS#Comparison
- candiddevmike 3y agoAFAIK they're on DOCSIS 3.0 and upgrading to DOCSIS 4
- pwarner 3y agoThese are the spec. Implementations vary. They vary in terms of chips, but also the way they get deployed on existing cable plant.
- akerl_ 3y agoYou may want to scroll down to the “throughput” section, instead of looking at the theoretical max. The theoretical max up and download aren’t additive. It’s like saying that an egg carton can hold a max of 12 white eggs or 12 brown eggs. Good luck putting 24 eggs in it. The DOCSIS standards carve up the available throughput, using some of that for upload and some for download.
