I was reading the post about the future of telco copper and how they plan on competing with cable speeds and I began to contemplate methods that could allow significantly faster speeds over conditioned twisted pair copper.
I based my thinking off of a few things
1. Cable is a shared medium providing blazing fast speeds to subscribers.
2. Existing twisted pair vdsl services utilize individual or bonded pairs to provide mediocre speeds to consumers.
but what if..
Telcos utilized all pairs to a ped to provide a shared pipe back to the vRAD?
Example:
Suppose there is a pedestal within 1200 feet of the vRAD. Individually, each pair is worthy of single pair 55M profile (45 Mbps HSIA) service. If there are 10 twisted pairs in the ped, utilize them all for an aggregate theoretical speed of 550M (450 Mbps) HSIA shared amongst the houses that are normally served by that pedestal. Instead of each of the 10 homes being capped at 45 Mbps, they are free to utilize more bandwidth as they see fit.
This is assuming all 10 houses don't simulataneously subscribe to and/or utilize bandwidth higher than 45 Mbps simultaneously, I can imagine 1 power user being able to pay for and subscribe to 200 Mbps internet utilizing this method while the other 9 houses use Netflix and all use a meager 10-20 Mbps each without anyone complaining.
However, limitations will still apply for those further down the line. I know that those that live ~4000 ft can only be allowed 19M (12 Mbps HSIA) profiles which would only allow for an aggregate throughput of 190M (120 Mbps HSIA) speeds, but I'm sure that the guys who live ~4000 feet would appreciate at least being offered 30-45 Mbps HSIA instead of being limited to a mere 12.
These are just my thoughts regarding the future of existing twisted pair.
I read that the 7330 ISAM can only support up to 8 pair bonding therefore there is research and development to be done but this is a method that can transform existing twisted pair into a shared medium to provide higher speeds over longer distances
and this doesn't even factor in breakthroughs that can be made with vectoring and phantom pairs while also utilizing this method.
I also realize that the removal of IPTV from U-verse will allow more overhead for further increases in internet speeds assuming this method is followed.
What do you think?
