| DOCSIS 3.0 vs U-Verse
I understand your frustration, I live in Apt Complex where the fiber terminates to my DSLAM about 50 yards where I'm sitting right now and I'm synced at 8000k and 512k up. There are a lot of financial/technical hybrids that are in love with milking as much out of this copper infrastructure which is only delaying the inevitable. Like Alexander Gramm Bell’s technology, copper had a good run and it’s time to recycle it.
However, I disagree with your comparison to U-Verse (VDSL2) vs DOCSIS (3.0) it’s going to be close but not decisive. The fundamental flaw with DOCSIS is CSMA-CD, the shared architecture, and most cable company’s lack of distance infrastructure. The faster you clock a CSMA-CD link, you lose proportionally more throughput due to the back-off timers and the listen timers. While yes were going to see hudge advertised link speeds with DOCSIS 3.0 you’re on average limited to 70% of that link and that is if you’re the ONLY person on that link. So take your 300 meg bonded channel connection, take 70% of it (210) and share that with a couple hundred neighbors. Where as VDSL, yes you loose bandwidth as your distance increases from the DSLAM, but you’re going to stay around 100 megs just for you. Then you take away CSMA-CD and all of the backoff timers and jitter from that type of link, and you have a low latency reliable connection. The Cable companies are just going to lure you in with big numbers and hope you don't use it.
But none of this helps you right now, ADSL (original spec) is the new dial-up and it’s quite pathetic that many customers are still limited to it. I was in the military for a while so I can tell you first hand that writing your congressman can work. I’ve seen direct, decisive action taken after a letter was written to a congressman, and write the FCC as well. In my opinion the FCC should be limited to managing the radio spectrum and if someone runs copper/fiber lines, that’s their property and it shouldn’t be taxed. |
