pipe dream (wont happen for a long time) I don't see cable providers really pushing this out in the next few years as it is impossible without major network upgrades. 2 96MHz wide upstream channels got to be joking. I don't think so as this would require the cable company to replace all amplifiers and it isn't worth it right now as cable providers are just now beginning to use 5-42MHz for upstream to its full potential for DOCSIS 3.0. Also every box, modem and anything to do with the cable plant would have to be replaced as they wouldn't be able to keep linear TV and that would require substantial capital meaning things from DTAs, digtial adapters, VOD servers, and even CMTSs would have to be upgraded. Too costly for now maybe in 2020! We may get lucky and cable decides to figure out that don't touch 5-1500MHz and go for 3GHz cable systems and do a second upstream and downstream path from 1500MHz to 3000MHz and put DOCSIS 3.1 there otherwise we won't ever see it.
more realistic approach would have been 12MHz/24MHz wide upstream channels and 48MHz wide downstream channels with OFDM. 96MHz and 192MHz is too greedy! No cable system is going to have 192MHz to set aside just for downstream on DOCSIS 3.1. The real solution for several years is expanding the downstream to 16 QAM carriers and make the upstream 4 QAMs wide 6.4MHz as anything better than that is unrealistic. TWC in my area is finally able to move 3 6.4MHz upstreams with a legacy 3.2MHz upstream so don't look for DOCSIS 3.1 for years.
Re: Suffer not worth the $$$ too much equipment to just sent to the dump. The best option would be to run dedicated fiber for customers that want the very fast internet tiers like comcast does otherwise the cost to invest in a single cable plant may be too much to realize the ROI for offering faster speeds. There is no such thing as suffering the loss of cable channels because cable channels are not going anywhere. And the whole idea of a dumb pipe won't work because they will find ways to charge overages for internet.
what happened to 24MHz wide channels?

Re: Suffer Yeah, I don't get it. 1gb fiber is commodity pricing, why spend so much money on equipment that will be outdated quickly and limited by physics in the near future?
10gb over copper is going to be near the limit before the price for tech will start to sky-rocket.
FTTH It would be cheaper for the provider to go Fiber To The Home, than to deploy this. Comcast is already taking the fiber route in Washington, D.C.
Re: FTTH And EVENTUALLY will get there everywhere (at least as far as the nearest strand/light pole) but in the meantime they won't abandon years of investment in the current plant when it can continue to morph into faster and faster speeds while extending the fiber plant further into the last mile.
