said by tmc8080:Unless you're being fed by fibre then there is... DOCSIS cannot handle that kind of upstream performance without splitting the nodes to very small number of users and VDSL2 cannot provide that kind of upstream speed without very short loop lengths, a lot of people are on longer loop lengths that can barely handle 10Mbps up or less. You roll out 50Mbps up with DOCSIS without splitting the nodes very small and the tiny amount of capacity at the node will be congested in no time. These are technical limitations of the access technology. The situation will improve a bit with DOCSIS 3.1 and VDSL2 vectoring but these are a ways off.
There is no good reason why every service provider shouldn't be at 50 megabits down/upstream
Sorry to ruin your silly rant with facts.
based on the amount of profit all telco & cablecos have chewed down on existing networks it could have paid for 3 or 4 generations of new investment when times were very good for them, instead they squandered many opportunities to do right by the customer. the circumstances they are in today are mostly their own doing..
They can't upgrade in the past to technology that has not existed until quite recently or doesn't exist yet.
