Web Access Over Power Lines
anaesthetica writes "The CSMonitor is reporting that power companies may now be able to break into the internet provider market, giving consumers a third option, outside of telephone and cable companies. From the article, "Broadband over Power Lines (BPL), with investments from big-name companies including Google and IBM, is beginning to move beyond small trial projects to deploying systems for large communities." Earthlink may offer BPL as soon as next year. Apparently, a major source of opposition to BPL is operators of ham radios."
"Apparently, a major source of opposition to BPL is operators of ham radios."
Of course. It's the ham operators that actually understand the potential for BPL to cause harmful RF interference. The rest of the world won't care until it affects them personally. Ignoring the advise of ham radio operators is like ignoring the advise of the bomb squad when there's a bomb in a subway. Ok, so it's not as drastic, but it's still quite silly.
My lame blog.
It's also more then just Amateur Radio and Police, Fire and Abulance radios that can be affected. You TV can be affected as well as AM/FM broadcast band. Has anyone here ever been living near a noisy (as in RF) powerline? Power companies are notorius for letting things get bad before the fix them. As long as the wire delivers power, they do not care if it spews RF all over the place. Notching the Ham band out will not be effective. The power company must not have heard of Harmonics.....sure the main signal is notched out but what about the harmonic of the signal? Harmonics is what is going to cause this to be a bigger then ham radio thing. Also, BPL is being promoted by the FCC to be able to bring broadband internet to rural America and that just ain't so. Rural users typically have older power delivery systems when compared to the urban folks and those are not always going to be able to carry BPL.
The BIG reason power companies want BPL is so that THEY can use it for reading your meter. They want to make your electric meter to be adressable and able to be read over the internet. They also want to have teh transformers and what not be able to report their status over it as well. BPL is about cutting some costs for electrical companies and it's just a bonus that they can add ISP to thier hat as well.

For someone who is supposedly advocating "egalitarianism-oriented" free speech, you seem awfully quick to hand a PUBLIC RESOURCE called the RF spectrum over to a tiny group of PRIVATE CORPORATIONS.
In case you haven't thought about it yet, there is nothing "free" or "egalitarian" about BPL. It will be under corporate control, accessible only to those who can/will pay for it. Contrast this with amateur radio, which is more or less the last vestige of non-corporate, decentralized, communications technology left in existence. Anyone who can pass a simple test can get on the air and communicate worldwide without any dependence on power companies, telecom giants, or huge media conglomerates.
Destroying public access to the radio spectrum via BPL is just one more move that will keep people dependent on corporations for EVERYTHING. Don't you think that individuals should have SOMEway to communicate and disseminate information that doesn't depend on big business?

I can't imagine where you got that silly idea...
The fundamental technology is still distance limited. In fact, given natural and artificial interference factors from pre-existing spectrum users (not just ham radio operators, but everything on Shortwave) the distance limitations may be even more severe than those imposed by the telcos.
Hams aren't the only objecting group. They're merely the loudest. Most of the others, such as short wave broadcasters and trans-oceanic air traffic, Ship to shore Marine communications and the like don't have a constituency that the FCC will give much credence to.
Nearly fifty percent of all graduates come from the bottom half of the class!
You should support amateur radio.
We provide critical communication after a disaster. When four hurricanes hit my area a year ago, guess who handled communications between red cross shelters? Power was out... The phone lines were down... The cell towers were down... The wind was too fierce to send smoke signals. Amateur radio operators were just about the only method of communication.
And if BPL comes to town, there goes amateur radio. If the airwaves are blanketed with noise, nobody will invest in the expensive equipment, and of course they will not get any practice using it. And even IF the disaster wiped out the BPL noise in that area, a ham would have nobody to talk to, becuase the neighboring states would still have the noise.
So, let's assume that BPL does notch out amateur radio frequencies. Then, only some military channels, some shortwave channels, and some ship-to-shore radio frequencies are knocked out. No big deal, unless you happen to be on a ship or trying to listen to shortwave radio.
So, notching is not the answer. If you notch out ALL frequencies, then you can't transmit anything. And the more you notch out, the less bandwidth you have for sending data. And no matter WHERE your energies go, you will step on somebody's toes.
The frequencies below 30MHz (and sometimes all frequencies below 50MHz) have the wonderful quality of being able to travel entirely around the world. It is not uncommon for an amateur radio operator to talk to people thousands of miles away on at little at 5 watts. So, it is not hard to see that if BPL is introduced in every community in the USA, this will make the HF spectrum mostly unusable for THE ENTIRE WORLD. Actually, I am surprised that there is not some sort of treaty that would prevent this BPL nonsense.
Actually, I would love for the power companies to provide broadband. But they should have to do it over shielded cables, just like everybody else.
"-1 Troll" is the apparently the same as "-1 I disagree with you."
Emergency supplies in area B, where power is still on, can not recive signal from area A ham because area B BPL is still interfering with the signal.
There are two points in a point to point link, if one point has too much noise to hear the other, there is no way to communicate. So basically Hams in disaster areas would only be able to communicate with other Hams in other disaster areas.
