Electric Companies Get Involved With Broadband

Billosaur writes "The Marketplace Morning Report on NPR has an interesting piece on how electric companies are getting into the high-speed Internet business with 'Broadband over Power Lines', or BPL." From the article: "By purchasing the right equipment power companies can quickly offer Internet service to millions of new customers. There are several pilot projects being launched in the US, including one in the Pittsburgh suburb of Monroeville. That service is being offered by Duquesne Broadband -- a spinout of the local power company.'"

    The power line wasn't a giant freaking unshielded antenna! This tehcnology has been effecting communications gear all over the place. Its a very very bad idea in its current form.

      It's more than a bad idea, it's a forking NIGHTMARE. Even for non-hams like me, the radiated fields from the lines will cause all kinds of problems. BPL produces a horiffic amount of conducted line noise, in violation of the FCC's own regulations, and further pollute an already overcrowded section of bandwidth (DC to light). BPL may be good for the power companies' profit margins, but it's bad for EVERYONE.

      And that's my professional opinion.

      Do some Googling. The problem is exactly that the power lines are designed to transmit power at 50/60 Hz. BPL works by forcing these lines to transmit RF signals. The reason why BPL is such a technical disaster is that power lines and transformers don't act like proper RF transmission lines... they act like antennas.

      The right way to implement BPL is for the power companies to use their rights-of-way to run fiber to the customer premises.... or at least to the pole outside, where an 802.11 link handles the last 100 meters.

      Do you mean to be comparing the speed of the data (Mbps) to the frequency of the powerline? Where are you trying to get at with that calculation?

      The issue at hand here is that powerlines are unshielded. They were never intended to carry RF, and act as very, very big antennas when they are used in this way.

      Once you load up a power line with a radio signal, you have the potential to start messing with communications all over the spectrum. The noisiest response to this has been from Amateur Radio operators, but government agencies who might be affected also think BPL is a bad idea. It's not a particularly good idea to knock out communications by the Red Cross, Salvation Army, and other emergency response agencies.

      To use an analogy, think about how the water lines in your house would respond if you pressurized them beyond their capacity. They'd leak, yes? Or how about using them to carry corrosive chemicals instead of water? They weren't designed to do that, and it will cause problems.

  2. Municipal Power & Fiber by mysqlrocks · · Score: 4, Interesting

    Where I live (Burlington, VT) the city provides both electricity and fiber optic service. It's Interesting that it was more practical to run new fiber optics throughout the city than to use existing power lines, since the city already owns the electric department.

  3. More competition is better, whatever it is! by postbigbang · · Score: 4, Interesting

    BPL advocates will tell you that it's not fttp. And it's not going to be at cable speeds for a long while, but has lots of possibilities.

    But here are the salient positive points:

    1) these guys are by their nature, net-neutral and while they're utilities, they don't live behind ancient telco models
    2) reliability is a serious culture within the power community; these guys have trucks and know how to use them
    3) the electrical utilities have the largest amount of unused communications easements and right-of-ways in the USA
    4) the utilities in the EU are riding this wave quickly; they go everywhere, while the old tired fat ex-PTTs slumber
    5) more competition keeps the telco and cable companies honest. We need alternatives.

    So, I say: party on, BPL!

  4. Power Co pays ME for a pos. net flow of data! by potus98 · · Score: 4, Funny

    Most power companies are required to buy extra electriciy if you generate more power for the grid than you consume. This usually only applies to folks with solar panels and other sources of power that end up contributing to the grid. They get to watch their power meters run backwards!

    I wonder if the same principle could be applied to net data flows! I would love to be paid by the power company for massive file sharing since I would be contributing more to the 'net than I consume.

    And in other news, the combined cable television industry announced today that it's possible to provide power-over broadband-lines. Their spokesman said:

    "What is coax but insulated copper conductor. With Edison's DC delivery methods, tried and proven over a hundred years ago, a single conductor with ground return has always been feasible. Now we will free you from the greedy power companies and their unfair monopolies one and for all. Bwahahaha!"

  7. The problems with BPL by wb8wsf · · Score: 5, Interesting

    BPL is one of those things which sounds good or at least interesting
    at the start, but the deeper you go the less decent it gets.

    The problem boils down to the fact that a BPL system emits RF (radio
    frequency) energy, causing interference to entities that use those
    frequencies. The FCC has been put into an interesting spot here, as
    they realize that the problems generated by it are real, but are also
    being pushed by the Bush administration to move forward on this.

    Ham radio operators are definitely negatively affected by this. Hams
    by their nature deal with "weak signals", which the noise generated
    by BPL tends to clobber, making many of the "shortwave" (ie, below
    30MHz) bands less than useful.

    If you care to see a pretty good response to this go to www.arrl.org
    and look for BPL.

    This is a real horror for hams. Least anyone think that ham radio
    is out of date in this era of advanced technology, talk with officials
    down south who dealt with Katrina, or in Neq York City on September 11th.
    BPL pits big money interests against litterally amateurs, with the latter
    group figting back, and being at least partly successful, in getting
    the FCC to deal/recognize interference complaints, and getting these
    systems cleaner.

    What will happen, I cannot say. But I look to systems in Europe
    and Asia where broadband exists and doesn't use BPL, and see systems
    which offer far better service.

  8. Nope by Valdrax · · Score: 4, Interesting

    No, they're just steam-rollering ahead realizing that they have far, far more potential customers to reach than hobbyists (valuable hobbyists, but hobbyists nonetheless) to put out.

    I'd personally like the FCC to put an axe in this idea, but it's never going to happen. Once they get enough of a userbase, it'll be impossible to shut them down politically. Ham radio will just die and the public simply won't know what they've lost because they don't use it themselves.

    I would suggest you look at Corinex in particular, at 200megabit it doesn't cause any major interference. For that matter, here in Peoria we have a broad scale deployment of BOPL and considering my coworker is a ham enthusiast in the same town I find it odd that this fud is still being spread around. He's got no issues within a mile of the thing nor has the telecom company doing all the work had any issues reported to them. They are one of our sponsors so we generally talk to the people who would know. It makes sense that rf over the power lines would get amplified greatly but in practice it doesn't happen especially when you do it right at each substation. Our ISP runs fiber to each substation and then attached more or less a gateway that connects the fiber to the power lines.
