BPL: The Internet's Fool's Gold
Joe Barr writes "One of the more fascinating tidbits of information I came across while researching this story on NewsForge about BPL, the fatally flawed wannabe-broadband-provider technology, was that at the very same time the FCC was downplaying the threat of the interference BPL creates, the FCC's very own test results were showing just the opposite."
Filters for your outlets... And I thought DSL was bad. -jh
Never underestimate the power of corrupt legislatures and utility companies to force adoption of bad technologies:

A few BPL trials have been dropped because the technology just cannot compete. But the threat is still real. Once fixed wireless is available everywhere, BPL
technology's only hope of success is through open graft and bribery.
My hope would be that Texans would give their much-abused highway signs a break from using them for target practice and begin utilizing the numerous BPL devices that will be
available. But old habits die hard.
Give a man a fish and you have fed him for today. Teach a man to fish, and he'll say "WHERE'S MY FISH, YOU IDIOT?"
If you read the article you would have learned that hams aren't the only ones affected by the interference generated by BPL.
So if the fire department using 20th century radios is unable to communicate and your house burns down is that OK with you?
BPL is flawed technology trying to be rammed down people's throats. Those nerdy hams were just the first to see the wolf in sheep's clothing thats all.

You're funny.
Amateur radio operators (note: I am not one) are the first people to use their "lovably nerdy hobby" in practically every major emergency to coordinate resources and get help to where it's needed most. Amateur radio is far, far more than some little hobby. Making things difficult or impossible for this (small and growing smaller, sadly) portion of the population is not something to be taken lightly. They're not your neighbourhood vintage car restorer.
HAM operators have proven their worth in emergency situations (like natural disasters), and the local HAM club here has a diesel generator ready to go in case we ever have something nasty like an earthquake or a tsunami. If the choice is between some technology that leaks RF like no tomorrow and keeping a "nerd hobby" that actually can do us good, then I'll pick the "nerd hobby" any day of the week.
But it ain't just HAM hobbiests. Your radio and emergency channels will be knocked out of the sky as well. Now maybe you can do without Easy Listening AM Gold, but while you've got your lovely broadband-over-power-line, you better hope your house doesn't catch fire or you or one of your loved ones has a heart attack, because guess what, you are, to put it bluntly, fucked.

That's kind of a truism. Thing is, he's advising a ground-up solution. There's no room for tearing down the infrastructure to rebuild from scratch -- you have to work within the existing framework. If he was in Marconi's position and had the ability to redefine the radio world in terms of his theories, I'd call him a genius. But what he's looking for is simply undoable, so I call him a kook.
That's something of a PR illusion perpetuated by the ARRL. Hams do sometimes have a role in well-coordinated emergency scenarios -- in those situations it's a ham's job to make sure information gets to where it needs to go, nothing more. That's important enough in and of itself, but a lot of hams tend to have a rather inflated opinion of themselves. Emergency-trained hams who think they're first responders as opposed to support personnel tend to cause more trouble than good.
All I have in my area is one monopolistic cable provider, anything for some competition. ... we can't be trusted to communicate, and should place our trust in the corporations to "help" (read: censor) with our e-mail.
Like many other cable providers, they block off vital TCP/IP ports. No incoming port 80 for my web server - no way do the corporations want us to turn into producers on the internet, the corporations only want us to be consumers of their own content. Blocked outgoing port 25, crippling my mail server - naturally, only corporations should be allowed to send e-mail

No? Are you even still reading this? If so then ask yourself this, does your "hobby" provide emergency communications during disasters? Does it? DOES IT? Was it THERE during the TSUNAMIS like amateur radio was?
What about after the hurricanes? After Charlie tore trough Port Charlotte and knocked down all local sheriff and fire radio towers ham radio operators were there cranking up new towers, equipping the sheriff and first responders with new radios so they could save lives. They even used that tracking system I mentioned on all of the vehicles involved in rescue operations so that way the first responders could coordinate their vehicles more efficiently...
But you've probably stopped reading. Like I could care. All I want to do is enlighten those who read your comment, give them a different point of view. Show them that Amateur Radio DOES matter, is an important part of our lives and will be around a long, long time. BPL or no.

Which is why this stupid idea is so seductive. Everybody wants broadband, everybody has power lines. What's the problem?
(1) It doesn't work, and really can't work. (2) It has bad negative consequences for other systems (forget ham radio, and consider the emergency radio bands it overlaps). (3) Even if it did work, it would be more expensive and less available than current broadband channels.
I mean, everybody who wants broadband probably has water pipes, too. Why not broadband over tapwater? Pulse-modulate the chlorine and fluorine levels in the pipes, and read the bits right off there... BPL isn't much more sensible than BT when you look at it closely.
It can transmit as well as receive.
There have been many attempts and sales of devices in the past which purports to use the entire power grid as an antenna, whose signals is routed through our special little box to your TV set, yours for only $19.95 postpaid, etc.
Yeh, you get the signal you wanted, as well as more crap you didn't than you can shake your stick at. Its like getting a free restaurant meal, thoroughly mixed with a bucket of garbage.
So, you put wide spectral content signal back into the power grid, you are gonna radiate our all over. This has been known since the days of Tesla and Marconi. Nothing new here.
We already have enough problem with accidental corona discharges filling the RF spectrum with unwanted broadband hash. Just one dirty insulator will screw up the RF environment for miles around.
Technically, yes, power lines could transmit data, but they were not optimized for this. Its old-style 300-ohm TV twin-lead at its best. It was notorious for picking up stray signals.
I do not think BPL was ever designed to send signals... it's designed like a cat trap, whose purpose is to trap investor dollars. Dollars from people quick to part with their money but slow to pick up the technical acumen to verify their claims.
One more thing, don't knock amateur radio HAMS. They are the last breed of guys we have who have a personal interest in RF. Most people seem as ignorant of their stuff as they are about their computers, and have no earthly idea how it works - as they just complain and pay someone else to make it work. Most amateur radio operators know exactly how their stuff works - especially if you ever meet one who builds from scratch. Its really unusual these days to talk to anyone who knows this field from its most fundamental levels, and their advice should be taken very seriously. Personally, I fear the passing of these guys who build things from the ground up, as many of the incoming people build things with dollars, and have no idea how it works - and physics, not finance, makes the ultimate decision of whether something will work or not.
