Re: Now comes with twice as many crap channels as before!
If it was me, I would install the Vyyo Inc 3 Ghz spectrum overlay. It would effectively upgrade the cable system to 3 Ghz without having to rebuild the cable systems.
In some areas, Cox is deploying it, »www.cable360.net/ct/news/thewire/22781.html .
That would allow for quite a bit more channel bonding as well. |

Can you please give a couple of sentences that puts this into meaning for those of us who are on the primer? What exactly is happening here?

Just curious, have you looked into how that works? From what I just read, it's that same ultra-wideband crap that's flopped a bunch of times. They don't upgrade the whole network to 3Ghz, rather it overlays and injects data at certain points in the network. |

@shawcable.net | All they are doing is putting in 3Ghz passives. In other words, mainline splitters and taps. The plant is still at the mercy of their actives (amplifiers), which stated is 1 Ghz. It'll be a while before they start mass producing 3 Gig amps. |

Phoenix, AZ | The attenuation that 3ghz signal would cause would require all plant to be rebuilt to compensate....
It' can get bad enough on a 750 plant I would hate to be at the end of a line on a 3ghz plant.... |

| Correct.
Now to another point. I think sometimes that people need to stop reading b2b press releases for their information. The 3ghz gear is trying to be pushed to gain sales. It's a pure business move of someone trying to hawk their gear. In the real world, as to where it means anything to the consumer, it's not being implemented because it's a huge mess for cable operators to implement. (as you said above)
This just brings us back to the "it works in the lab, but lets see it in the field" point. |

What this does is add quite a bit of capacity to the cable system. It doubles downstream capacity and adding four times the amount of upstream bandwidth.[Depending on how it is setup .] The other part about it, is that it will work with existing equipment. There is some work needed, like amps and cable taps changed to a 3 Ghz capable one, and some equipment at the headend will have to be added.
This would add room for quite a bit of HD, faster internet, and more channels without upgrading to FTTP.
It is also considerable less, $125 per home passed, vs. $1,500 - $2,000 for FTTP.

Wasn't Cox talking about deploying that on just a "few select" plant runs? Mainly bushiness areas to bring down the costs to service medium businesses?
