said by iansltx:In contrast, 6M down, 1.5M up can be deployed via either single-pair Annex M or pair-bonded Annex A ADSL2+. The latter can cover a LOT of territory if things are set up correctly. 6/1.5 is also within reach for many wireless technologies. And cable providers have been able to hit 6/1.5 on 100% of their plant for years. That said, far from being an already-surpassed goal, plenty of areas nonetheless can't get 6/1.5 service, and would greatly benefit from having it; with that speed, you can watch HD Netflix and do tuff like online backup without tearing your hair out.
Put another way, let's get most of the US to a reliable 6/1.5. Then worry about the next step (12/3 anyone?).
The new American motto: "Good Enough!"
