Ashburn, VA | Bandwidth Worries? With the aggressive caps that Cox employs, why would they be concerned about bandwidth?
»www.cox.com/policy/limitations.asp
What, do they expect to cram tons of new customers on their existing network? Is that why they need to improve their infrastructure? |

will allow the cable provider to increase standard definition channels from 100 to 200+ and HD channels past 100+ |

kudos:2 | Maybe they'll be coming along with the upgrades. Can the current tuners continue to be utilized by the MSOs moving HSI QAM channels to the added frequency range and maintaining TV in the existing range? |

| Time Warner went and replaced our gear with 1ghz stuff last year. But they haven't bothered to deploy new set tops, nor DOCSIS 3. Maybe they'll do something useful with it by 2020.

I've been with Cox for over 10 years, regularly blow through my caps and only got one abuse letter back in the @Home days.
I haven't seen anyone recently (within the last few years) get an abuse letter or get cancelled for going over the caps. Cox during the earlier network management debate used examples of their users using over 900MB/mo so I don't think Cox is enforcing their advertised cap in any of their markets. |

said by Da Man:Where are the 1GHZ tuners to watch these new channels? I believe DOCSIS3 cable modems can do 1GHz.
Most STBs are 860MHz but they won't need more than that in the interim as the data services will be moved out of that space.
FiOS only uses 860MHz for its video portion.
Furthermore if video can be moved to MPEG4 they can cram in even more channels without reducing quality. It's almost inevitable anyway as programming providers are moving to MPEG4 and the DBS providers already have. |

I know that FiOS does not, as the data is a completely different wavelength than their video service. Another advantage that FiOS has over cable, for now, is that they do not have a ton of analog channels to provide. Once the cable companies can switch to all digital channels, this will free up a huge chunk of bandwidth as well. |

It's almost inevitable anyway as programming providers are moving to MPEG4 and the DBS providers already have. A move to MPEG4 would require brand new STBs as the current generation only has hardware MPEG2 decoders. At that time it would only make sense to deploy MPEG4 boxes that had 1GHz tuners. |

I don't see swapping out boxes for customers who want, say an additional HD tier to be a problem. After all, the cable companies always tout "free" equipment upgrades as a reason to go to cable vs satellite.
Some customer owned equipment (such as TiVo) also has MPEG-4 built in as well. |

FiOS and cable are doing the same thing, except the FiOS is using wavelengths of light. Cable is using wavelength of RF. They are both electromagnetic waves.
But separate spectrums of whatever don't matter at all. All that matters is total bandwidth allocated, whether it is continuous or broken up across the spectrum.
Since Cox does plan on keeping some level of analog service, they will most likely put some digital video (digital cable) over 860MHz and towards 1GHz.
The article also mentioned MPEG-4 so it is likely that they will end up deploying new STBs with 1GHz and MPEG-4 capability. |

Ashburn, VA | Cable and FiOS are not the same. The full 860MHz spectrum from FiOS TV is ONLY used for their TV services and has nothing to do with the GPON or BPON ONT data bandwidth. FiOS uses the same 860MHz spectrum only so that they can utilize existing cable equipment at the homes.
Cable uses the 860MHz spectrum for everything. |

2 edits | This isn't about 860MHz. This is about 1GHz.
And since it's about 1GHz, Cox will have the full 860MHz and more that FiOS has. Furthermore it's actually 820MHz forward path that FiOS uses now, since 5-42 is used for the return and 0-5 is wasted. That 820MHz and more bandwidth will be available for video if cable companies move to 1GHz.
Furthermore with MPEG-4 they will be able to carry the same quality video since MPEG-4 can carry the same quality video using less bandwidth.
To the end user it will be an equivalent offering to what FiOS has for the video service, and until Verizon offers more than 320MBps for internet service, the cable companies can match whatever Verizon decides to offer, not that the average home user can pay for or fully use a 20MBps, let alone a 320MBps connection anyway.
And yes it is one an the same. If you disagree, I suggest you go back to high school and retake some of your science classes, especially those about electromagnetic waves. |

It's not the same, Fios uses a separate wavelength of fiber that does not take away any capacity from their digital television service. Cable uses QAM channels that take up a certain amount of the frequency spectrum. Such as a 6MHz channel. There are a limited number that can be distributed. Within this 860MHz spectrum, all TV, data, and voice services are transmitted. For FiOS, ONLY the TV service is used for the ENTIRE 860MHz spectrum.
It's different.

My FiOS ONT is rated up to 1.2 GHz right now. They are also ready to provide MPEG-4, but with the same issues that cable has providing the necessary STB's to everyone. The latest Motorola boxes that many FiOS customers have can already do MPEG-4. |

1 edit | 1. We are talking about cable going to 1GHz, not 860MHz.
2. A different wavelength of RF is the same concept as different wavelength of light.
Pay attention in science class next time. |

I've never disputed this, if you read my comments I have been saying that FiOS and cable are not the same. And you keep suggesting that cable is doing the same thing with wavelengths over the RF spectrum in the same way that FiOS is using separate wavelengths over optical cable. This is not true. They are not doing the same thing.
There is a lot more bandwidth available with FTTH, even considering the upgrade to the 1GHz spectrum. |

I think TWC has bigger issues than just deploying Docsis 3.
Running 1GHz may bring out issues in many older homes with RG-59U. I had an issue on 1 link in my house that is RG59U (DTV replaced the other 2 with RG6 a few years back).
Worked fine on DTV - but TWC digital gear didn't like it.
I ended up taking an old(er) RG6 that ran the long way around and works Ok.
Many 'older' houses may end up with issues similar to mine.
This is probably similar to AT&T with old POTS wire having issues.
