1 edit | Hello AT&T - This is what is needed
"While AT&T is struggling to fit a single HD channel into the 20 Mbps Lightspeed, Verizon will be able to run five HD 9 Mbps channels and 50 Mbps of data."
Maybe they (AT&T) will wake up someday. Maybe... Please wake up! Please.

| Actually VZ will be able to run the full 100 mbs and offer more than 5 hdtv channels at once on one piece of fiber.
The fiber line actually carries 10 different wave lengths or colors of laser light if you will. Only one wavelength is used for data. And one wave length can hit gigs not just megs per second. The other waves are used for other services in the fios rollout. That's not all there is to fiber optic rollout, the capacity is so much higher. But this is the easiest way to explain it with out getting super involved. |

| Yeah, let's not get all technical talking about lambdas, GPONs and such we'll let them do that here »book.itzero.com/read/cisco/0512/···ec2.html
All I'm saying is that AT&Ts thinking that FTTN will be sufficient is flawed. They should call someone at VZ to get a clue on how to build a network.

I think at&t has more up their sleeve than they are letting on. I have heard rumors of a 25Mb service sometime near the year end, after they squeeze everyone for 6Mb. It's simple business strategy. There is no need right now to just "plop" 25Mb out there. Sure, it would be nice, but that is not how business works.
I have also heard similar numbers as posted above on the HD bandwidth that Verizon claims. I think at&t said theirs is something like that.
I just wouldn't be so hellbent on saying 6/1 is all the bandwith that is going to be available. I think (and hope) there is more in store, something the rumor mill hasn't got a hold of. |

Uhhh...essentially Verizon's plan as listed here is FTTN/FTTC. AT&T's plan with pair-bonding can accomplish the same thing. What's the problem? Do you hate the copper that much that you'll hate it even if it does the same job? |

Uhm, no. Verizon is not going to offer 5 HD channels and 50 Mbps of data. First of all, they can't. Its called bandwidth allocation. Customers requiring 5 simultaneous HD screens are few and far between, sure everyone would like 5 streams, but are they going to get it, probably not. Furthermore no customer deserves 50 Mbps of data, which they cannot afford.
Lightspeed is a midterm technology, geared to get the customer ready for IPTV. AT&T is deploying FTTN technology for a reason, this reason is upgradeability. FTTN cabinets and equipment will be easily upgradeable to FTTC or FTTP technologies. AT&T is trying to get the technology, delivery, and backhaul built up before they go FTTC or FTTP, why?? Because a makes sense.
When it comes to high speed internet We suffer from buffet syndrome. Concetrate on what is needed now and build your network along with the pace.
Also understand that Verizon is doing FTTP mostly in areas with aerial deployments or new neighborhoods. |

Yes, I do!  Copper has limited bandwidth. Plus the are more maintenance costs with copper involved. AT&T's plan is copper up to 3000' whereas VZ's plan is maybe up to 600'.
Go over 1000' feet and the speeds degrade massively.
VDSL Downstream Rates vs. Distance-
12.96 - 13.8 Mbps 4500 ft
25.92 - 27.6 Mbps 3000 ft
51.84 - 55.2 Mbps 1000 ft |

AFAIK, ATT Lightspeed has no provisions for a FiOS-like PON. I dont think ATT is putting in the 100s of strands fiber that Verizon uses for PON. If anything, ATT's fiber will have to be coverted to a electrical signal and sent through a backbone-grade router in a RT cabinet, and then upgraded to have 100s/1000s of fiber going to each home split off that 1 incoming fiber, and again we have the HFC DOCSIS problem, cable cos dont want to split nodes or replace the last mile coax, and that ATT will not want to invest in a $10,000-$50,000 OC192 or OC96 linecard to backhaul to the CO for the 100s/1000s of users on that RT, nor a router capables of 10 gigabits of routing speed. PONs like FiOS (1:32 split) are split 1:8 upto 1:64 as i recall. The telco still needs alot of backhaul to the CO fibers, I dont think ATT is installing these all these extra fibers. Verizon is doing it right, ATT is just patches, shortcuts, and gimicks and soon its nothing except a mountain of ducttape. If ATT is installing enough backhaul strands of fiber to upgrade to a PON, someone correct me. |

Thanks for the figures. I knew VDSL deteroriated quickly with distance. Apparently some here feel that everyone lives in an apartment complex or multi-unit dwelling where they can just run a few hundred feet and everyone will get 100Mbps, LOL.
DOCSIS 3.0 is more than formidable competition for VDSL, it will wipe the floor with it. |

By that time there will probably be something faster than VDSL2 out. VDSL2 is about double the speed of VDSL on short loops. |

The only problem with that is the cable companies need to field DOCSIS 3.0 to wipe the floor with VDSL. And by the time the cable companies get 3.0 fielded the telco's already have VDSL2 in the pipes and FTTC being the norm in greenbuilds.
25megs at a mile is impressive(ADSL2+/VDSL2). Especially with pair bonding.
Not to mention the backhaul. The telco's are already upgrading theirs to GigE. |

Companies who feed this insanity of dsl through 2006:
pricele$$
12 pings and maybe one pong 18000ft- (worthless dsl speed)
for everything else there's worthless at&t, and some weirdo at verizon still touting this idea!! |
