| Will Sonic.Net offer VDSL? Seems like bonded VDSL would be a VERY nice bump over bonded ADSL2+... will they offer it? |

VDSL is a technology for very high speeds over short distances. It is suitable when the ISP has equipment on every street corner but doesn't really work if the equipment is located in a CO (unless you live next door to it). I do not think it would make much sense for Sonic to offer VDSL (perhaps VDSL2 since its 'usable' range is closer to ADSL2+, but not VDSL).

We plan to evaluate VDSL2 for potential deployment, but it would likely only be provisioned for customers who are 5,000ft from the telephone exchange office.

| Got it. Thanks. I'm getting 20MBPS w/ bonded fusion service... would love a speed bump, and I don't want to change service providers  . I like Sonic.Net's customer service! |

If you need a place to test it, I am within that distance from my C.O. |

Definitely count me in also.
I've already got an VDSL compliant modem too!

kudos:7 | While there are huge and obvious flaws in the data on this chart (ADSL1 only does 8Mbps, for example, and ADSL2+ maintains an advantage over ADSL1 at greater distances than shown), it shows the general concept:
At >5,000ft, VDSL2 offers about the same performance as ADSL2+.
»en.wikipedia.org/wiki/File:ADSL_···each.gif
Can anyone else find a better chart showing rate/reach of VDSL2, ADSL2+, ADSL2 and ADSL1?

Same here (about 11000ft). Please hurry up that build-out in San Francisco, I can't wait for Sonic fiber to arrive in Sunnyvale

Found »nbnmyths.files.wordpress.com/201···sons.jpg at »nbnmyths.wordpress.com/2010/09/26/12/ but it's only ADSL2+ and VDSL[12].
Here's one from Cisco: »www.cisco.com/en/US/prod/collate···31-1.jpg |

kudos:7 | Thanks - the first two appear to come from page five of this old paper:
»www.netsys.com.tw/support/downlo···2_WP.pdf
(the version in the paper has different colors, and includes feet and meters which is nice.)
The Cisco one is near useless because on the bandwidth scale it is logarithmic, and at the area that matters (short distance), there's little info.
All do make the point though: VDSL2 provides substantial gains for short loops, tapering off to little or no gain beyond 5,000ft.
FYI, stats on customer lengths in our network as a percentage of total.
5000ft 78%, or said another way, >4000ft & 5000ft, 11%. This gives us some guidance on who is going to see very fast speeds (the 3%, who would see about a doubling), respectable gains of 50%-75% over their current speed (another 8%), and those who will see modest gains, perhaps 10%-25% (the 11%.)
Note though one additional gain in VDSL2 - packet transfer mode (PTM) replaces ATM as the L2 protocol. PTM is more efficient, almost totally eliminating the "cell tax" that ATM has on each 53 byte cell. This results in a reduction in layer-2 overhead of around 10%, so an equivalent VDSL2 (w/PTM) sync of X versus an ADSL2+ (w/ATM) sync of X will result in roughly 10% better TCP/IP throughput.

<3000ft 4%
<4000ft 11%
<5000ft 22% I think a more interesting metric would be % of users behind an RT. If somehow you can get those people to get Fusion/fiber somehow... but maybe the current infrastructure and policy landscape would not allow that. Of my immediate family, everyone except for my parents qualify for Fusion--the rest including me are all behind an RT. |

Bay Area wide, it's 40% that cannot be served, and 60% of premises can.
In some regions it's worse (Santa Rosa, San Jose) and in others it's better (Berkeley, San Francisco.)
San Fran is the best - the city is roughly 7 miles across and 7 miles tall, but it contains nine telco exchanges. There are only a few remote terminals. In SF, over 90% of homes can obtain Fusion.
At the other end of the spectrum, despite being roughly the same dimensions, Santa Rosa has only two COs, plus a whopping fifty-three remote terminals. In Santa Rosa, about 25% of homes can obtain Fusion.
For more on "why no Fusion served out of RTs", see my article "America’s Intentional Broadband Duopoly": »corp.sonic.net/ceo/2011/09/02/am···duopoly/
This means we must build FTTH, as it solves the issue - new infrastructure means you can build it wherever you like.
