Broadband via Power Cables trials in Scotland
Wacko writes "Scottish Hydro-Electric have started a trial of Broadband internet access via power lines. Just plug the modem into any power point in your house, with no need for additional lines into the house, and reasonably priced too. Details are a bit scketchy right now but interesting to see how the trial goes."
The project was abandoned.
Heh... My ADSL connection is a reliable 2.5Mbps, for about $35 a month (Sweden). Care to immigrate? OTOH, you might want to consider Japan instead. They've recently rolled out 14(!)Mbps ADSL for about $20(!) a month.
Mmmmm.... Bandwidth.... Drool...

Anything you say will be held against you.
If been in a trial in NL, and it worked sorta OK
until I plugged a dodgy TV into a near socket.
Apparently the TV blew back a few volts down the line which in its turn took down the modem....
Not a pleasant experience.
If an experiment works, something has gone wrong.
Power lines are noisy, and not just a little bit. Then you've got the whole shielding issue (mentioned in other posts). X10 made a home communication thing that used powerlines as the means of transmission (had to build a reciever for one in college) and the amount of crap that comes through on those lines is disgusting.
Look at the reviews of home networking / print sharing equipment over powerlines... the speed is pretty poor. Heres a review over at firingsquad While those speeds may be fine for internet sharing in one household, imagine trying to put together an entire town?
Maybe they've got something else going on though. Best of luck to them.
I work in the broadband industry for one of the larger cable companies and the question I have with this technology is how they break up the users so that they don't overload a particular box. In the cable industry we have CMTS boxes that handle a group of people from a particular node. From my understanding the way powerlines are layed out is completely different. Just a thought.
Here in Virginia, USA, the power company "Dominion Power" is closely tied to "Dominion Communications". The issue is simple. If you want to run copper (or fiber) between two locations, you need continuous right-of-way . You need legal access to a swath of land between both locations that has no point where you do not have the ability to dig a trench. There are only 3 groups that have this. Governments (along the roads), Railroads (like the way Qwest did it) and power companies. (unless I dimm-wittedly forgot somebody)
It seems silly to me for an organization that HAS continuous righ-of-ways to bother with troubled technologies when they can actually lay their own fiber, and charge silly amounts of money to other companies to lease their left over strands.

Seriously.
I live in rural Canada and I *am* watching and praying.
This is because people like me are on ultra long phone loops and can get 31.2 on a good day. Some can only get 21.6. There is not ADSL. Cable TV is not wired. A few wireless options are insanely expensive. Satellite only has modem by upstream and the lag is bad. There are NO plans for expansion of traditional broadband to my area. Telcos won't pull in a T1 and even if they did, the tree density is so high that 802.11b neighborhood sharing so to pay for it is out of the question and houses are 1+ km apart so cat5 is out too.
This is worth geting excited about.
It was under the brandname "Powerline", and yes, it failed and was abandoned. This was due to noise on the line more than anything else - a huge chunk of the electricity switching network in the UK, the National Grid, is *old* and electrically noisy. When power is switched it causes a spike on the circuit which then rather noisily settles down, trashing the data that was transmitted. Not to mention all the inductive properties of wires for collecting interference. What we found was that the technology was sound, and it did indeed work (there are still some of the schools we used for the trial using it), just a lot slower than was hoped. Too slow for viable commercial use it was felt.
Basically, if you are a power company looking to get into data, and have a modern, low-noise, distribution network, then this may well be viable. Of course, for rural Scotland this will be a lot more viable than urban Manchester with fibre running everywhere, because you could charge more for it and still be cheaper than the competing technologies. Or alternatively have better response times than them - Quake via satellite broadband? ROTFLMAO. ;)
