Littleton, CO | Read The Article? Did anyone bother to read the article?
announced the completion of a successful trial and targeted deployment of a new 100 megabit-per-second (Mbps) data service using the Narad Broadband Access Network (NBAN) and Cablevision's existing network facilities that pass more than 4.4 million homes and hundreds of thousands of businesses in the New York metropolitan area.

This doesn't sound like a residential service... and it doesn't sound like "vaporware" either.
This sounds like an extension of "Lightpath's Internet Access via Ethernet " which currently offers 'Flexible bandwidth options include 10, 50, 100, 150 and 300 Mbps '
It's probably a cheaper version..

| Its a docsis 2.0 flavor... capable of upto 400-500mbit symmetrical per node... Althoug 50-100mbit per user is likely. As most people generally don't hog the entire bandwidth all the time, this is still a shared network whereby even at the symmetrical speed -- if you upload near the 50mbit cap, your download speed gets compromised due to the acks being sent back are lagged... but this would probably account for a 10% decrease in speed (say 4-9megabits degrease).
Still, price, availability, and actual USAGE are key factors-- is this sustainable cost-wise to cablevision? OR have subscribers been keenly "conditioned" to expect not to peg the service up 50/50 24/7/365?
How severe would a "cappage" be?
 What will verizon's response be? Sit and wait, for how long after its been released? IMHO, Verizon can't take the chance that cablemodems provide faster speed than their best package at a fraction of the cost, especially not in their home-core market. (NY METRO) |

It's ethernet over coax.
DOCSIS 2 certainly cannot do 4-500Mbit symettrical per node without extensive work to the point where the node is more like a hubsite. You've still got the 42MHz limit on upstream path and there's only so much you can pack into the 37MHz max you can get out of that. Max for an upstream on DOCSIS 2 is 30.8Mbps. It's impossible with DOCSIS 2 to achieve 50Mbps in either direction.
Downstreams on DOCSIS 2 are still limited to 38Mbps as well, even giving each user their own downstream / CMTS card they could still only reach 38Mbit.
Read my post on a UK forum for more info:
