AT&T: 15 Mbps Internet connections "irrelevant"

"In the foreseeable future, having a 15 Mbps Internet capability is irrelevant because the backbone doesn't transport at those speeds," he told the conference attendees. Stephenson said that AT&T's field tests have shown "no discernable difference" between AT&T's 1.5 Mbps service and Comcast's 6 Mbps because the problem is not in the last mile but in the backbone."

Is this something held generally true in the US, or is it just pointed hair-talk? Sounds like "nobody should need more than 640kb of memory" all over again.

I can definately see a difference between 2 meg, 8 meg and even faster, even when web browsing, especially transferring large pictures when running gallery or alike. When I load with 130ms latency I get over 1 megabit/s and that's transatlantic with a lot of small objects to fetch. Most major newspapers here in Sweden will load at 5-10 megabit/s for me, and downloading streaming content ( will easily download at 10-20 megabit/s if bw is available. around a couple of megabits/s. (all measured with task-manager in XP, very scientific :P)

I can relate to there being a sweetspot around 1.5-3 megs/s when larger speed doesn't really give you a whole lot of more experience with webbrowsing, but the more people will start to use services like, the more bw they will need at their local pipe and of course backbone should be non-blocking or close to it...
