Re: Not Buying It While I don't doubt your expertise, a lot of us have cable connections at 30Mbps or higher and they seem to be just fine.
My 30 meg connection is close enough to 30 meg for me to be satisfied with it.
Sure, I'd love to have 20/20 or even 20/5 FiOS, but I can get 28/1.9 cable with consistent throughput and has consistent ping times.
Also, I thought that DOCSIS was digital, not analog.
What am I missing? |

| DOCSIS is digital, true. The analog reference is in regards to the era of initial distribution system construction which asserts the limitation. Other than complete system reconstruction and dependence on a fiber transportation back-bone there's not much more to play with.
Kudos to your exceptional connection. Let's hope that remains.
I'm curious are you within a major population density area? |
|
| I'm located in semi-rural Sussex County, NJ. We are about 50 miles from NYC.
We aren't a really rural "out in the sticks" area but we are not suburbs. We have 5 acre zoning, for example. |

I wonder how fast can you download if the upload are so small like 100/1
10mbps?
something advertise as 100mbps and having 1mbps upload is very shady
This is how cable get away with giving you next to nothing onthe upload side
Majority of us believe that we just leech and someone with super fast upload will magically appear out of thin air to fill their download pipe to the max  |
|
| With 30/2 I can download at 30 with no problems.
I would like more upload but I don't mind the download. |

coax can compete with fiber
if you push coax to its limits it can support quite a bit a 3 gigherts plant combined with switch digital video and mpeg4 and docsis 3 could easely support
100 megabit internet upload and download both
and support around 1000 hd channels plus have a lot more bandwidth left to use |

At some point the limitations of analog RF distribution (which is what "digital cable" rides on) will become unmanageable and the entire plant will have to be converted to true wideband operation without having it carved into 6 MHz channels. 3 GHz over coax is not trivial and unlikely. 100 megabit upload at the customer is a pipe dream without fiber. |

said by fifty nine:With 30/2 I can download at 30 with no problems. I would like more upload but I don't mind the download. if they give you more, it will bring their network down. will be crawling like a snail... it would bring their entire network to their feet... so its not their priority to have fast upload but to have faster download only. to hide the fact that their is limited upload capacity.
Like more user they love to brag about how much they can download while completely ignoring how fast they can upload
even 100/2 will put a smile on most user... including you 
why symmetric not possible? its shared
you and many other user are on 30/30 pipeline
at least 10 people are sharing 30/30, so it isn't obvious until most of you use it at same time then you see a drastic fluctuation... aint that the beauty of shared network? enjoy sharing bandwidth with many others in your neighborhood. |

| I don't think there are very many others on my node as my speeds are consistent day in day out.
In fact I just ran a test of transferring several 400MB files at 30Mbps. At 30Mbps down, it averaged 640k up. This is using wget on a CentOS box.
At 100MBps down you'll need around 2MBps up, minimum. Selling a 100MBps connection with 2MBps upload only is a bit silly, so maybe 10 or 20 up would be fine.
I would like to see them eventually move to fiber to the home, but there's plenty they can do with coax today. |

DOCSIS3 does support > 100Mbps speeds though.
In the real world this would of course be less with noise and the like, but this is largely because they are using the outdated 5-42MHz return path.
1GHz over coax is very much doable and if the video moves to MPEG-4 there will be even more room for data services. |

Last I heard nobody has been able to make upstream channel bonding work in a real environment.
I suspect that MPEG-4 (really X.264) may be more about increasing the HD quality(reducing the noticeable compression effects) without using any more bandwidth, rather than decreasing the (total) video bandwidth(same amount of bandwidth used, just at much higher quality picture). |
