| DOCSIS (all versions) support a download rate maximum of 42.88Mbit/s
Assuming the infrastructure is somewhere near certified levels of quality, you'll see them raise the bar again.
It might be that we need new cable modems to support DOCSIS 3.0 and really let rip  | |

Hi Lob, as you increase the speed you increase the need for higher Db signals (coax world). IF you do not have the reserve ie plenty of amplifiers or a fibre deep infrastructure then you are limited in what you can do. Gain and line extenders do not help you that much here as they increase the noise and thus increase the errors... You also need to have plenty of clean 75ohm cables and a return path. The problem with cablecom is their history. They were a tv signal distributor. TV requires no return path and only a wire down which to push the signal - point to multi-point infrastructure. With the decision to be a multiplay company they needed to upgrade the network to ensure all connections had a return path - I am sure you can remember around Y2K the change in the sockets and the introduction of a data socket to the standard radio and tv. This was the introduction of a return path allowing internet and other future technologies such as interactive tv.
When this work was done there was not the thought of throwing multiple 10s of Mbits down a cable just to allow internet. Now speed is king and in order for cablecom to match the pure IP world of Swisscom they need to get rid of old cable thereby reducing impedance and go fibre deep. If they do not do this then you have to question the business case ie how much longer can they face off against the now multiplay Swisscom?
Upgrading to 30-40Mbps will give them some time but and this is a big but only in some locations where the connection is clean. Go out to the half sticks ie not bumpkin country or to locations where they have not invested for a long time (say 25+ years) and they cannot deliver the service.
Fact is IF cablecom are not smart and do not act quickly their network will reduce to just Zurich, Basel, Geneva and Luzern and then they will lose much of the revenue and the monopoly they have. And then it is just a matter of time...
