    I think that it's a good idea, but users won't be switching soon. The only thing that might encourage users to switch to the power providers is if they can provide a way better plan, or they just want the convenience of paying it off on their power bill.

        i bet they would price it the same as the competition - maybe 5$ less. right now many locations (at least in, near and around my area) only have DSL or cable so it is hard to get companies to compete if they dont *have* to. if it is the same cost or cheaper than cable i would switch. hopefully enough other people will too. once the local companies lose enough subscribers there should, hopefully, be a price war.

    The article was light on the details of why the hams are opposed to this, except for the issue of whether or not it will interfere with their signals. If the BPL companies are offering to NOT interfere with the signal, why is there still opposition?

      The opposition, even with the offer of notching the offending frequencies, is that the notches that have been demonstrated don't do enough.

      You could say it lessens the interference by 50% or so, and that's not enough because ANY increase in the "noise floor" (the background signal that exists on a frequency which a signal must overcome in order to be heard) makes it more difficult for ham radio operators to use the frequency spectrum that they are licensed to use.

      One solution would be for ham radio operators to just increase the power they use. Unfortunately, most hams operate (on HF anyway) at their full power capacity. Also many hams enjoy the challenge of low-power communications of 5W or less (worldwide communications are possible on under 5W).

      The principle of the thing is that why should a commercial venture be able to do the things that, so far, no one has been allowed to do: emit RF across such an immense spectrum of frequencies, including those for which others have what the FCC calls "primary" usage granted to them.

      The ARRL has said that they do support a Motorola solution because it does not add any interference to the ham radio frequencies. So not all BPL is bad. Ham radio operators are opposed to those that are bad.

          A weak signal right on top of an antenna will swamp a powerful one at a distance if the power levels are equal at the reciever. I can cripple a Ham or CB setup by simply leaving a little 9v powered transmitter (in the case of CB, a walkie-talkie dead-keyed on the channel of most offense...) nearby. You won't be able to hear ANYTHING on the reciever wherever you do this to- it was a common fix for some idiot running a Linear being a problem on the CB band- they could get out, but they couldn't recieve over the little walkie-talkie on their fav channel. They'd think there was something wrong with their rig and quit doing it typically.

          What the real big problem is that the BPL systems are largely interfering with a piece of spectrum that has really good propagation characteristics. It's used by everyone for emergency communications worldwide in the case of a disaster; not just Hams have a problem with this- FEMA and other orgs like them does too.

          What pisses me off about all of this is that there's no real need for this BS- BPL can be done, done well, and it won't interfere with any critical services when it's done.

          Corridor Systems [corridor.net] has developed signal launchers and repeater systems to allow them to transform each line on a pole into a 10+ Mbit segment using 802.11 technology. This is accomplished by turning each of the lines on a power pole into a G-line waveguide (yes, you CAN do that sort of thing) that propagates the microwaves from an 802.11 system along the surface of the wires...

      As an Amateur Radio Operator I think I may be able to answer this question.

      Firstly, there are a fairly large number of licensed operators. Not everyone is active in the hobby, but it is the number of licensed operators that the ARRL (American Radio Relay League -- Amateur Radio's main 'club', so to speak) uses when confronting the FCC and other regulatory bodies (including Congress) about issues that are a concern to Amateur Radio.

      Secondly, as previously reported on Slashdot (no, I cannot find the article at the moment) the BPL companies' attempts to "notch out" the part of the BPL signal that interferes with Amateur Radio transmissions have not been very effective.

      Thirdly, while BPL is certainly a good idea in theory, and I for one would welcome our new BPL overlords if they can dispose with the interference on the Amateur Radio bands, there are still technical details to work out before it can be used harmoniously in conjunction with existing services, including Amateur Radio.

      Remember, Amateur Radio serves a critical role during emergencies to provide communication when other means are not available. If those power lines go down there will be no interference, but what if they are still up and there is a major emergency? Also, many Amateur bands are close to other public service bands. Yes, I know that the police are using cell phones now, but unless there is something that allows the cell towers to give priority to the police phones over my phone they police may be unable to communicate in an emergency.

      I know our local ambulance service uses radio. So does our fire service. BPL will interfere with them as well, though not to the same extent because they are shorter range.

      A little interference is not such a big deal with shorter range communications like the local fire and ambulance, but when you are trying to push a signal across the country, that small amount of interference is a major issue.

      I'm sure I'm going to get flamed for this, but such is life. These are the main issues to the best of my understanding. Again, I would love to see BPL work. I live out in the boonies and I can't even get cable, never mind DSL.

        unless there is something that allows the cell towers to give priority to the police phones over my phone they police may be unable to communicate in an emergency.

        In fact, that very point was recently demonstrated in London. From this article [com.com]:

        In the immediate aftermath, a statement from the U.K.'s largest network operator, Vodafone, said that an excessive number of calls had caused outages. The operator consequently set aside capacity for phone calls to emergency services.

        "Following the major incident in London today, Vodafone London switches are at capacity (which is very rare), so we're having to go into 'access overload' procedures, which means freeing up a proportion of capacity across London to ensure the police and emergency services can communicate," the company said.
      • When I was in the army there were some BPL performed. It was considered a fact that if BPL would be generally implemented the background noise within kilometers or tens of kilometers from powerlines the increase in background noise / interference would considerably reduce the maximum range of man-portable VHF radios.

        Electronic warfare would be even more badly hit as the devices used to gather radio intelligence can operate at the level of background interference.

        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.

          Also, consider that once BPL comes around, it probably won't be long before the same company sells digital phone over the same lines. Therefore, there will be internet and phone communications as long as BPL signal is up, and if lines or the signal are down, then ham can cut in.

      Because the current definition of "not interfering with" is based on fairly loose standards, because BPL noise could ruin the opportunity to use other parts of the RF spectrum in the future, but mainly because power-cabling is unshielded and currently so inefficient at broadband frequencies that they will initially have to use alot of signal, and radiation will be a given, regardless of what's promised.

      Think of this as background noise (eg like your neighbour's air conditioner). It may be quiet, but its noise still prevents you from hearing the birds clearly, the breeze in the trees, the buzz of the bees, etc. BPL radiation will reduce our ability to detect faint RF signals.

    Yes, the Amateur Radio community is in opposition to BPL, due to the high degree of RFI (radio frequency interference) that BPL puts out. The problem that not as many people are talking about is that this will also affect many fire/rescue/police radio frequencies, which occupy the same radio spectrum as the BPL systems interfere with. This could potentially cause severe problems in emergency situations. So no, it's not just a bunch of us HAMs whining about BPL "ruining our hobby".

Here your web browsing session will be available for 100s of miles along the path of those power lines, in places with easy access. Just set up a tent, open a laptop with proper antenna and enjoy.

    From the article:
    With BPL, utilities can quickly identify where outages have taken place, read meters remotely, and conduct preventive maintenance, such as replacing a transformer before it fails, by monitoring unusual "noise" on the system.
    One of the real reasons for this is the remote meter reading capability. It eliminates the need for manual meter reading (or, for places with remote read systems, to have a van drive by getting the data.) But, it allows this camel's nose into the tent: the meter will be smart enough to allow time-of-day-based rates for electricity, like large commercial customers already pay. You'll pay more for usage during peak hours, less for off-peak use. Note: this is fair, as during peak times, electricity often is generated using higher-cost sources such as natural gas plants.

    Hams are just canaries in this fight, not villains.

    BPL has been shown to cause radio interference to all users, amateur, military, and commercial. Michael Powell, then FCC chairman, squashed a report from the NTIA that said it cause [cq-vhf.com]interference>/a, and the FCC required that frequencies allocated to government use be "notched out." That leaves just us citizens unprotected and ungagged (at least for now).

    And before you say that HF radio isn't necessary anymore, and everyone who is anyone uses cell phones (of if they have buckets of money Iridium satphones) take a look at just one of thousands of uses, NOPAC [faa.gov]. Last night on 10.148 Mhz (square in the middle of the band that BPL trashes), I heard a Singapore Airlines flight over the Pacific contacting a NOPAC control station in Alaska asking for route planning information, right on the heels of a JAL flight doing the same thing. The NOPAC instructions have detailed accounts of how to use HF radio when over the Pacific, which is what I heard last night.

    Finally, the FCC didn't grant any license to BPL systems. Instead, it said that they would be allowed under Part 15 regulations. Those are the same regulations that govern radio controlled cars; in essence, they're allowed to use low power if they don't cause interference and if they accept interference. The NTIA and others argued that BPL was fundamentally different from a kid with a radio controlled car on 27Mhz, because BPL will be widespread both geographically and in spectrum -- occupying the entire area beteween 2MHz and 80Mhz.

    The result: a few critical government frequencies get notched out, and everybody else gets told to call the power company and complain "if" there is any problem. And in the few test cases where this has happened, even in test trials, getting the power company to do anything has taken months, and only a few even tried, and of those few that tried, all but about three had to discontinue the project becuase they couldn't resolve the Part 15 complaints.

    So yes, it hasn't happened widespread yet, and it hasn't caused widespread problems yet, but don't blame the people who are technically savvy enough to see what's going to happen.

    And finally, don't you think it's strange that energy companies are getting a big help from the current administration to get into the ISP business? I mean, it's not like there's any connection between energy companies and the Bush administration, is there?
