| 435101 | 2006-03-03 02:23:00 | I read an article a few years back stating that it is possible to transmit data through power cables. Could this be what vector are trying to do using their existing cabling? If this is whats happening, surely you should be able to turn on your oven an hour before you get home and have a roast ready when you arrive. I like that. |

| 435102 | 2006-03-03 02:46:00 | A fair amount of South Auckland has done undergrounding. They did Papatoetoe a few years back down Shirley Road, Rangitoto Road and surounding areas and BOY did it make a difference! Where I live in Papatoetoe they replaced all the poles last year. I don't think we will see any underground in my life time.. |

| 435103 | 2006-03-03 02:59:00 | You can have all the Auckland power lines underground. It only costs about $500 000 per km. Yell loud enough and the rest of NZ will pay. :thumbs: | Graham L (2) | ||
| 435104 | 2006-03-03 03:35:00 | I read an article a few years back stating that it is possible to transmit data through power cables. The technology exists, but the biggest problem/cost is in getting it to bypass the transformers. Last I heard every transformer required technology added to minimise signal loss. There's an oldish story here (www.wired.com) and a local trial here. (www.nzherald.co.nz) Cheers Billy 8-{) |

| 435105 | 2006-03-03 03:40:00 | The basic problem with it is that it radiates RF over a huge proportion of the HF and VHF spectrum. Communications services (air traffic control, taxis, emergency services, radio amateurs, etc, etc) are really enthusiastic about that prospect. | Graham L (2) | ||
| 435106 | 2006-03-03 04:08:00 | I remembered while i was overseas they were running 1mbps over power lines. Worked great.Would provide us a lot more competition if genuses energy able to provide this sort of technology but at the end wouldn't it connect back with telecom? |

| 435107 | 2006-03-03 04:23:00 | In Europe (including UK) and Japan, it has been trialled and has resulted in the door being all but locked for good on the technology. The US still seem to be persisting, and Australia is still looking at it. It's not that it does not work, as it works quite well. Its for the reasons Graham states, its the end problems for many essential users of the radio spectrum that causes the cessation. Despite some claims I have seen more recently, there is nothing that you can do to stop the interference, plus the faster the data transmission, the higher up in frequency the interference moves. Every house, street light etc becomes a quite effective radiator of the interference. |

| 435108 | 2006-03-03 04:28:00 | If they moved it to the GHz region and replaced all their power conductors with waveguide, it might be OK. But fibre would be cheaper. Power transmission lines are not good RF transmission lines. But any wires will radiate. That's the problem. | Graham L (2) | ||
