When will their speeds be at least 50, 75 and up for their upload?
When they start channel bonding more. Right now an upstream channel has ~27mbps after overhead SHARED between all users on the RF binder group (or "node" used loosely).
Most systems today are 4 downstream channels (152mbps after overhead) and 1 upstream (27mbps). The problem is people leave torrents running or stream their slingbox all day long, so it can be really easy to fill your whole upstream pipe 24/7 where most people will run out of hard drive space eventually and downstream isn't a 24/7/365 100% use threat...
Just FWIW I expected this to happen, as there is little incentive for me to purchase 30mbps service from Charter when my 15mbps powerboosts to 3/4th that on a regular basis...
well actually there is channels on the upstream that do not provide 27Mbps net. I know that the TWC system I am on has 4 upstream channels that are 3.2MHz wide QAM16/QAM64 mixed mode that have a max of 15Mbps per channel and they (Time Warner Cable) are bonding them here and most of the time my modem is connected to the QAM64 profile but sometimes it will degrade to QAM16 for short periods if there is noise on the line. Right now TWC is using in the Dallas cluster (North Texas) for upstream:
so right now each node has 60Mbps roughly on the upstream to give out to each customer and the fastest they offer right now on the upload is 5Mbps for their 30 Mbps, 50Mbps, and 75Mbps tiers and this is with upstream bonding so the chances of getting a solid 5Mbps upload a great right now as they are limiting the upload to 5Mbps. I am hearing that TWC is planning on increasing the top tier to 100Mbps down and 20Mbps or 25Mbps up in my area. But that is a few months off as they are having to remove additional analogs on the downstream side so they can move from 6 to 8 downstreams for the DOCSIS channels and possibly make some of the upstreams 6.4MHz wide channels.
