Cable Forum - View Single Post - Superhub 200Mbit coming soon? (According to a survey)

3.1 can offer an immediate improvement in upstream speeds over the current set up even without physical network changes. 3.1 also needs work on the downstream; there's a fair amount of linear TV and VOD there and finding the equivalent of another 33 free QAMs of downstream spectrum over the current band plan isn't trivial.

Regardless the CPE and standards support a far better practical upstream ratio than the predecessors.

It's also worth mentioning that the ratios deployed elsewhere in the world are quite different from those here which have historically been conservative on the upstream.

The USA come to mind as some who pushed upstream hard in the past. A 101/35 tier from Cablevision on DOCSIS 3.0 and 30/5 on US DOCSIS 2.0 come to mind.

VM and the rest of the Liberty Global group will be upgrading networks accordingly in any event.

It's a non-issue though as VM aren't going to be deploying a DOCSIS 3.1 product imminently, there's plenty of life left in DOCSIS 3.0.
