Internet over power poles

[rekees4300]

This is a new technology called AirGig that could revolutionize rural Internet access. AT&T is testing and if all goes well commercial deployment could occur within 9 to 12 months.

"Project AirGig technology involves placing small low-cost plastic antennas developed by AT&T Labs on top of existing power lines. These devices create a multi-gigabit signal that travels along or near the wire--but not actually through it."

Looks promising. They've been trying to come up with a way to use power lines for communication for years but they always hit a block from the inductance that transformers pose to higher frequency signals.

Please DO NOT sign me up! Up here that will be just as UNRELIABLE as Hydro One is now.

Our local power company quit the internet business, too much interference

Pretty light on the technical details. I wonder if it's just point-to-point wireless that uses an inductor to pull power directly from the wire without the need to splice the line.

but in a surprising way. Signals would not travel inside the power lines, but near the lines. "Low-cost plastic antennas and devices located along the power line" send wireless signals to each other, using the power lines as a guide, AT&T said. Quoted from ARS technica

Looks like they are using the power lines as "G lines".. This is a method of using a single conductor as an RF transmission line with low loss with proper "launchers" on each end. This may be what the plastic looking cones are. This is all from memory, as I have no actual info on this technique.

Aha... looks like I might have been right..

I guess when I start seeing things like "plastic antennas" then it sets my engineering BS meter off, plastic makes an incredibly poor conductor .

The nifty bit would be to get power indirectly from the line, point-to-point wireless has been done. There's a community based ISP up on one of the PNW islands here that use a microwave link over the sound to get in ~2gbps and then just stake 5Ghz wifi equipment with highly directional antennas to the nearest trees. Tons of trees out here in the PNW means you've got a lot of options when it comes to mounting hardware. If I remember correctly they just ran a power line down the the nearby house and required the homeowner to pay for the electricity in addition to the service costs.

Ah, found it: How a group of neighbors created their own Internet service | Ars Technica Was up on Orcas island.

Here is a little info about G lines.

I am wondering if the "plastic" launchers are infused with something metalic.

The telephone poles remind me of the vampire tap spacing on thicknet. :laughing:

My B.I.L works for the local telephone utility. He told me about this technology about 3-4 years ago. Not sure why but they did not peruse it. Probably enough competition with every other option out there now.

If it actually works it should be real cheap to deploy. Burying cable is expensive.

Whether they work or not, that mounting will make them a great target for lightning strikes.

There will be little pieces all over the ground....

As well as target practice

For sure ... they kinda resemble birds Wonder if one would need to be mounted on every pole?

I did some research on it. ATT bought the company developing it. It is a mesh network scheme using 30 Ghz line of site links. Inductive pickup on the power lines to power each node. The testing is being done in the southern US, and there was a comment that northern states could be more of a challenge with snow.

I wonder if the menonites would have to abandon their beloved internet, seeing as the devil is in the wires or some such thing.

There was some commercial a few years ago by a large corporation, with Sean Connery as the narrator. They showed a high tension power corridor, saying something about information traveling along these wires. This nonsense bothered me so much, I wrote the company. For whatever reason, I never saw the commercial again.
