| | Give me a break AT&T: who are you trying to fool? U-Verse is hardly revolutionary. Lets see; fiber to the node, copper into the home. I do believe cable came up with that about 15 years ago. Cox is already pumping 12Mbps (and PowerBoosts to 20+Mbps)/1Mbps into my house, and I can have 100 different HD "streams" going at the same time.
Face the music, U-Verse is a "me too" service that's years behind the cable FTTN model its trying to imitate. That's pretty sad.

Waterbury, CT | And, you ain't lyin either.
In 3 or 4 months time, It will be ten years...count em..TEN years..since I had my first cable hsi connection.
In fact, I was Insights first customer in Central Ohio to get hooked up. (actually..it was the predecessor to insight).
I recall those T1 speeds well. Especially given so many were just beginning to even get unlimited dialup.
Most cable co's bit the bullet very early on..and spent big bucks..especially for those days..to improve their networks to get in the FTTN game. But, even at that..they had something the telco's don't have..coaxil for the last mile.
Today..At&t comes lollying along..promoting their uverse as being next generation. A service the cable co's rolled out so long ago..and arguably, even much better given their coaxial cable last mile networks.
You are right.
Who are they trying to fool?
Obviously, at 100k customers and counting..out of a "uverse" of 17.3 million broadband subs they have..not very many at all.
Sadly, and I do mean that..they're nothing but 10 years late and 15 billion dollars short of doing what it is they really need to do.
I really think they need to understand that this time..I think the cable co's are out to kill them. Triple play..getting in the phone business now..docsis 3.0 up and coming..
It's just all a VERY bad scenario for AT&T I fear.
The GOOD news is, they can still turn it around by quickly announcing they're abandoning this strategy.
And going with FTTH instead.
They don't have much time though.
Not much at all.

No way man, that's impossible for a company like AT&T. There is no change of them being proactive or agile in the marketplace -- it's a paradox.
Unless someone (who?) buys T and drags them kicking and screaming in a different direction, I predict a 100% chance that U-verse will be fully deployed before they start thinking about what's next. It's ingrained in the corporate culture. | |
| | | | Lets crunch some numbers for all those concerned that AT&T's U-verse isn't a next gen network.
Let me first start off saying I've been a TWC RR customer for about 8 years, mainly because the local phone company (bellsotuh/AT&T) hasn't delivered anything to this area that is any better than what TWC offers. I prefer cable companies over phone companies.
But you have to really look at the numbers to really see why U-verse is just as capable and next gen as any network currently in place.
Coax, is capable of carrying 5-6 Gbps of data, assuming it was all digital. Fact of the matter it's not, and 80% or so of it is reserved for analog only. The small chunk of capacity left on the coax must deliver all the digital and premium channels, all the movies on demand, both SD and HD. VOIP phone service, and cable modem service.
Lets calculate bandwidth:
Coax:
Node = 100-500 users, sharing 38 Mbps of bandwidth.
even at 100 users, that calculates to less than half a megabit ratio between all the users.
U-verse:
27 Mbps bandwidth available to each user, 6 mbps for internet dedicated.
so those 100 people have collective access to 600 Mbps (6x100), versus cable's 38.
Coax Docsis 3:
Assuming 100 people on a node sharing 160 Mbps makes for a 1.5 Mbps per person ratio of bandwidth. It then becomes over 3 Mbps if the cable operator is running a double wide channel of 320 Mbps.
U-verse pair bonding:
1 pair = 27-100+ Mbps depending on distance.
2 pair = 50-200+ Mbps depending on distance.
bandwidth increases sequentially with additional pairs.
At this stage it's really up to AT&T how much bandwidth they will provision for a bonded line. There's also been talk about making the bandwidth available for internet access flexible, so if a user is not watching any TV, they could have access to 27-50-100-200 Mbps depending what their setup is, until they turn on a tv, which would decrease their speed by a few megabits for a SD broadcast or nearly 10 mbps for a HD broadcast.
Sure, you don't have all those analog channels being piped into your home... You can't watch 100 HD channels at once, but who can even watch that many HD channels simultaneously to begin with. Until the average American has 100 HD tv's in their home, or 50 HD-DVR's or even hundreds of SD sets, it's really a moot point to argue that U-verse isn't next gen. It's rather limited now, but once things get kicked into full swing, U-verse will easily be able to provide a number of HD streams, SD streams, and enough internet bandwidth for almost any user. | |

Only if you live in a Walgreen's TV commercial (the ideal world) in reality the additional bandwidth will be much less something in the 20-30%

As you squeeze more bandwidth from VDSL2 you will run into additional problems in the form of interference, lower noise margins, crosstalk, higher CRC/FEC error rates how do you plan to compensate for that

| | | | | | Re: Give me a break VDSL interference is an issue blown out of proportion. The same issues happen with T-1s and somehow they've got those to work reliably. | |
| | | | | | | Re: Give me a break Is it now? He was going on about more than just interference but also lower noise margins. The copper currently in use isn't getting any younger, you know. My ADSL2 experience with Earthlink's phone/DSL over the horrid copper line, so that it had to be trained down to less than half the maximum offered bandwidth to achieve stability. And that Uverse experience he linked to doesn't seem all that blown out of proportion from where I'm sitting. | |
| | | | | | | | Re: Give me a break The uverse experience he linked to is one guy with a problem that more than likely has nothing to do with interference from another line. | |

Wouldn't 20% of 5-6 Gbps like 1-1.25 Gbps? So that would be approx 33 times 38 Mbps....
