Re: It's a joke, people.
Reading their FAQ it says that metal or plastic pipe can be used, and that the signal can get through as long as the gas is not cut off (completely) by a valve. This would suggest that they are sending the signal 'through' the gas itself and using the pipe mearely as a containment vessel so that the signal does not leak out (like light bouncing though a fiber line).

It's what is known in radio as a Waveguide. Mostly used at microwave frequencies. |

Ever here of these things called satellites? Mars rover? Hubble? Yeah, I know you don't NEED gas to transmit a signal, but the post I was responding to said that you CAN'T transmit a signal through gas. I was simply trying to point out that, while gas isn't necessary, you can, in fact, transmit a signal through gas and it's done every day. |

If you read what they say, it's obviously not the pipe, and it's obviously wireless. I'm no radio engineer, but it sounds like the pipe acts as a waveguide.
Equally obviously, the gas is not essential to the wireless propagation, but nevertheless the signal does travel through the gas.

My original point was, after reading the companie's vague press release, that they would use something like those home networking AC plugs that make use of in-house electrical wiring to network at 1Mbps. Maybe I'm missing the boat but I don't think they're going to transmit using gas as a medium but rather the pipes going to your house and not what's IN the pipes. |

I would say they are using the gas, since they said metal or plastic, the signal could still get through. They also said that the gas has be be able to flow to the house (not completely cut-off by a valve) to work properly. So my guess is they are sending a type of 'electronic wave' through the gas to get there.
In short, if you get your gas shut off (not paying the bills?), your internet is shut off as well.

DaneJasper: Its not a joke, however here are the issues:
UltraWideBand currently has a limited range as provided by the FCC for wireless transmission. As of today, if Broadband in Gas were to be accomplished, you would need an Ultrawideband transmitter every 30 feet under the road by the gas line itself. UWB was approved for wireless for SHORT Range transmissions. Now, if the FCC would approve increased range exclusive to broadband in gas, there could be less transmitters needed and less road ripups required. Assuming roadripups every 30 feet, the cost would be still be less than rolling out fiber since there would be no cost of fiber cables nor splicing and devices will be low cost.
According to Nethercomm "Broadband-in-Gas delivers unmatched levels of connectivity by making use of Ultra Wideband technology to wirelessly broadcast information in a way that is both safe and reliable by using the private spectrum isolated within natural gas pipelines."
Since they use "private spectrum", and since UWB by nature is NOT private spectrum since you are using pulses over all the frequency bands, testing would need to be done to see if there is any signal leakage outside and to what maximum poweroutput you can put in the gas line. Thorough testing would need to be done with wireless signals around a gas line using the various gas line materials in place. Newer gas lines are not made of metal, but I would gather a PVC or other composite material. So there are all sorts of complications in the mix.
Could such potentially be doable? Its definitely worth investigating because the natural gas line is yet another pipe that is in the home that travels all over. We already have testing of Powerline Broadband. And now the gas companies also will be able to experiment with their OWN version of broadband.
Between Powerline Broadband and Broadband in Gas technology, Broadband in Gas is more plausible because it is essentially for all practical purposes wireless Ultrawideband but just confined to the area of the natural gas line so you have a consistent path.
The Broadband in Gas senario allows for the transmission path that one would NOT be able to get with the regular airwaves and also because its more isolated, it may be able to get provisions for more range as well.

Last time I checked, air was a gas. Don't be silly. The signal is a disturbance in the luminiferous ether. Every 19th-century physicist knows that.
