There's a neighborhood somewhere here in the Raleigh-Durham area where Progress Energy is testing this in conjunction with Earthlink.

Pros:
[tab]- Symmetric service (same upload & download speeds)
[tab]- Possibly cheaper than DSL or cablemodem
[tab]- No bundling (you only get the good rate if you buy the unlimited long-distance calling plan or five premium channels)

Cons:
[tab]- Still a shared resource -- your neighbors might be network pigs and eat all the bandwidth.
[tab]- If the power goes out, even if you have a big UPS, you still lose network connectivity.

I'm wondering how easy it will be to eavesdrop on the data. Power lines, typically, are not shielded.

I think I'd rather lose the network: a small annoyance.

BPL (Broadband on Power Lines) advocates claim WIFI is more porous.

I think this is just another case of

"power to the people"

So currently do you find yourself still browsing Tek-Tips while the powers out? [lol]

Actually, yes DrJavaJoe. Electrical power can relatively easily be replaced with batteries and/or generators. But internet connectivity is a different matter. You may still want to have the Cable or DSL connection available in that case.

Don't get me wrong I see the disadvantage, I'm just picturing this group setting around at home in the dark answering threads.

Not good news if you happen to have any reliance on radio transmissions and live anywhere near someone doing this. I can't think of a better way to create radio interference than put a radio-frequency signal on a wire suspended by poles right outside my house.

(yes, yes, I know, the people selling the idea say it doesn't do that, but people selling ideas aren't always the best source of information on down-sides...)

 
Is data degradation a real possibility by this method?

The article does mention that the power companies have to bypass transformers and install repeaters.



With this technology, I have this dread that my BPL adapter or the broadband powerline-tap it connects to will short out. Then instead of your computer's receiving a digital signal of a few volts at a few milliamps, it recieves a 60Hz analog signal of a few thousand volts at a few amps.

You are too right.

I once had a client that had a laser printer in the corner of a glassed-in porch. Lightning struck that part of the building and went to ground through that printer. The printer was okay except for the scorching on the case -- it was one of those indestructible HP LaserJet II printers.

The computer to which that printer was connected had a daughter-card printer controller. When the lightning struck, enough current went through that card to vaporize part of the main controller IC. A triangle-shaped piece about 1/3 inch on each side was blown off the face of the chip.

The thing I like about this idea is that I am not dependant on other services to get my intermet access. I only use my phone line for internet access. I use my cell phone for everything else. I do not have cable, nor do I want it. It would be nice to be able to not have the phone line also.

I would worry about power spikes and such though. (This from as a kid stuck a bobbie pin in a socket to charge it up as I was shooting my brothers as they were getting ready for a date :-) ) Yes, it was shocking...

A network connection over some cables? Been there, done that...

I'm waiting for power over wireless :)

<marc> i wonder what will happen if i press this...[ul][li]please tell us if our suggestion has helped[/li][li]need some help? faq581-3339[/li][/ul]
 
That's been done, too. If you live close enough to a major transmitter and put up a big enough aerial, you can power a lightbulb. But it's at cost of cutting out thousands of people's radio reception, so the transmitter people tend to be a bit uppity about it...
 
Im excited about the potential of net over powerlines. I work for a chain of quick shops scattered accross rual oklahoma. A lot of small towns dont even have dial up right now.

if it is to be it's up to me
 
I don't know why testers liked BPL. But, I think many of us here snicker because power has been a thorny issue the history of computers. I mean we have to buy expensive surge protectors, UPS and, fried computer chips are everywhere.

In that light, I think introducing BPL will probably engender clean electrical supply as a by-product. So, we may well be witnessing the birth of 2 industries, not one.
