Broadband access through common electric outlets

how the HELL is this possible?

Probably just adds a rider frequency on the electricity running through the house, kind of like X10 for home automation. So, you'd effectively plug your broadband connection into the wall instead of a router. Pretty cool.

I've never heard of this before. It seems possible. But damn, that's really freaking cool.

Welcome to 5 years before 2001!

Whatever magical number that is... :D

Yes welcome, but in his defense...nothing has happened with it since it was thought up. Who has the net over power lines???? No one I have heard about...

me neither. i know it has been worked on before, but never front page news on Yahoo. that makes me think it is closer to becoming a reality.

Audio or video data are just variations in a sine wave......ANY sine wave. This technology isn't all that new. Years back technology to develop data transfer on the magnetic flux fields which surrounded insulated wires was the source of much debate and spawn the "twisted pair technology" scam, which relieved many investors of some of their cash, even a senator and a couple millionaires.

To date the inherent risks associated with transferring data on relatively high-powered transmission cables was that most of the circuitry developed to minipulate these signals was not capable of handling such power levels, being more conducive to signal transfer on the millivolt scale....making radio and television signals ideal for data transmission. Then came fiber optics, then broadband, making it possible to transmit and recieve thousands of channels via the same transmission line.

The problems with the latest technology I see, would be more on how to control, therefore market it. First, you would have to make it worthwhile for the power companies to hetrodyne data signals onto their existing power signals. This would make these signals available to virtually every house on their power grids. The regulation device being the magical circuitry installed in the house to extract the broadband data from electrical current would have to be complicated enough to avoid bootleg copy-cats from reproducing the circuitry designed for this process. It would also need to be capable of reducing the power levels of these signals to make them usable for all existing appliances, yet still retain broadband charcateristics.

Another determent which could present problems for this type of technology would be NOISE. Miles and miles of mostly uninsulated power lines carrying data equates to miles and miles of "antenna" which would be super sensitive to ANY deviation in the Earth's natural or man-made magnetic fields. One bad transformer along the route and BAM, the data signal is lost to random, chaotic noise spikes......there goes CSI.

It would be interesting to watch not only the evolution of this technology, but it's implementaion as well. Nuclear powered service stations wouldn't bode well in a gas powered society. I suspect this process will endure the same reciprocations.

I'm happy, and I hope it turns out GREAT!

I'm tired of the lack of competition keeping prices high. I heard this stuff is much faster than cable (maybe?) and if they can provide it for the same price that will make my cable price lower....perfect!

I had a Motorola Power Line network at home eight years ago. It sucked really badly. I still have it somewhere. Hopefully this new stuff will be much, much better than the original crap.

you could take cat5 ethernet cable and snake it through ceiling tiles past flourescent lights and that would interfere with the signal. i can't imagine how that would work with unshielded, noncrossover wire with so many possible disruptions.

Wow! I hope the service becomes a reality. I really want internet at home, but I just don't want to sign up for a land-line. I don't need the extra bills and hassles. I'd rather just pay the electrical company more on one check rather than keep track of multiple utility bills. Sorry, I just like to keep my monthly payments as simple as possible...even if it costs a little more.

i think its been in a few european markets for couple of years, and its been/being tested in a few american markets right now.

that's how my parents house is run. in one of the rooms, the cat5 goes directly over (laying ontop) of a light fixture. been like that for almost a year now and there aren't any collisions and no packet loss issues.

i'm guessing you don't have cable? :p

Running a cat5 cable over a light fixture won't really cause any problems, (possibly if you run it directly over the ballast on a flourescent light, but it would have to be a very poorly-built ballast). I've seen cables running directly over more than 30 unshielded lights before, without significant signal degradation.

As for the EoP system, it's been marketed for several years, but it's more costly to implement than a standard cat5 system, and can't sustain the same speeds (or couldn't up until now).

And the data signal doesn't come from the power company. Even with the new system, you still have to have a third-party internet connection available. You buy the EoP device and plug it into both the wall and the incoming internet device. You then buy adapters that plug into the wall and connect to your ethernet cards (or possibly buy new ethernet cards that plug directly into the wall).

what will be cool is when you can just plug your computer into the wall and it just has internet without any other cables...no adapters or anything.

The big problem is that there is no way to carry the signal accross a Transformer so you have to do something special to get around that issues, so it still would have deployment issues.

Good news is I'm pretty sure the FCC gave the OK to transmit a digital signal of powerlines so now it's just a logistical issue.

That is definitely the coolest part, hooray for making things easier! I really hopes this becomes an efficient source of internet in the next few years. MadRonin, you said you had something similar and it sucked, but how did it suck? Was it slow or just unreliable?

Yeah...no cable, no internet, no land line. Only monthly bills are apartment, car insurance, cell phone and electric/water.

I'm not so sure it would work that way. My take on it is that your home wiring would simply replace any CAT5 you might use. So... Let's say you have Internet via your cable... So, you'd plug your cable coax into your cable modem, then plug your cable modem into the wall to create the network. You can then access the network via any of the outlets in the house.

I work for a power company in the southeast... we have been testing this for a few years now and are close to making it available to the public.
