Electric Companies Get Involved With Broadband 221

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.'"

      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 [fcc.gov], 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.

    Previous discussion of broadband over powerlines that I've read discussed it as an alternative to wireless or wiring your home...really small networks that then plug into a traditional connection. I'm curious how you would handle multiple users on one line. You're not just running half a dozen or so connections into a hub and multiplexing the signals. The power grid is huge! Along those lines, what about capacitance and interference? Wouldn't those kill the range?
    • There's no reason they can't be tying into fiber at some points, maybe even running their own fiber parallel to high-tension lines, and putting concentrators at substations to take residental data connections and dump them over to the fiber for the longer haul. No idea how they ARE doing it, though, but that's a mission for google.

    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.

    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!

    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.

    BPL is only being pushed because so many people are stupid enough to believe that if they have electricity, they will be able to get BPL.

    "quickly offer Internet service to millions of new customers" they say.

    This is not true. They can't run the service over high voltage lines.

    They have to fiber out to medium voltage (7,200 volts) lines and then offload from fiber ($$) to the unshielded lines.

    The lines may be 7,200 volts, but to comply with section 15 the data is transmitted somewhere closer to 1 volt.

    Emergency frequencies tend to be low because the low attenuation rate allows for greater travel. BPL being sent at 1 volt attenuates quickly so their workaround is to use EMRGENCY FREQUENCIES to transmit data on the power lines.

    Even at 1 volt it is enough to disturb radio and emergency communications because med voltage power lines are basically a big antenna.

    The problem with being only about 1 volt is that the signal must be cleaned and re-amplified every few hundred feed (more equipment, $).

    medium voltage lines are stepped down to 240 volt drops to peoples homes but the data could not survive this. The result is the need for a CT coupler (yes, more $) to bypass the transformer and again reinsert the signal onto the shielded line.

    When all is said and done you have a service that is expensive enough to run that it will no be a rural broadband solution.

    At best it will be available to areas that already have a choice between Cable, DSL, Fiber, and soon WiMAX.

    For the high maintenance costs of keeping BPL signal leakage from PBL deployments you could just run fiber right to the home.

    Also, BPL maintenance and inline equipment = network (read Power) outages.

    Besides, internet access is a very step for power companies. By the time they establish data centers, mail platforms etc. there will be a slew of better alternatives that won't cause power outages.

    Maybe they should instead focus on providing reliable power service or clean energy.

Every transformer is a barrier that requires a rugged powered device to bridge the Internet signal for those four housholds. These are fundamental constraints to which no reasonable engineer expects to find a solution.
