way way out | Oh No interference!! Do you know that my Microwave has a very bad relationship with my portable phone and wirless internet access points?
SO WE MUST BAN MICROWAVES!! its interfearing with my wireless access!
Do you know my neighbors baby monitor comes accross on my portable phone once and a while...
BAN BABY MONITORS!!!
HUH?
So what is a little interference? let the market decide which service is more important....

Will you sign my petition to do just that.? Because I think it's our responsibility to enforce all the laws that haven't been passed yet.
It is also my responsibility to alert each and every one of you to the potential consequences of various ordinary everyday online activities you might be performing which could eventually lead to *The Death Penalty* (or affect your parents' credit rating)
Our studies have shown that this horrible BPL is so dangerous to society at large that petitions are being drawn up at this very moment to stop it forever! Cruel and inhuman punishments are being carefully described in tiny paragraphs that explain in exact detail the effects of BPL.That conflict with the established laws of Physic's.Also which,itself, is impossibly being modified in order to accommodate THE FUTURE of BPL.  | |

Long Beach, NY | Re: Oh No interference!! Competition is only competition if it can truly compete.
Go and read the execution costs for BPL. Look at the reality that the rural areas will most likely not get this any quicker than DSL or cable.
Do you think that Mercedes was threatened by the imports of Yugo into this country? Which one is still imported? Sure, they are both cars, but one was so clearly inferior that it imploded rather than caught on.
With the current demands for broadband speeds and the interests in future expansion, folks should look at the psysical evidence and be willing to admit that the Mercedes-like quality they want will not be delivered by Yugo-like competition.
I think that we all want competition, so it will raise the bar on technology while hopefully reducing costs. BPL, specifically throwing broadband on unshielded copper power lines is a messy implementation. Since this might be the only way for the power companies to find a piece of the broadband pie, they will keep throwing broadband at their power lines hoping that some of it will stick.
As a delivery of broadband, BPL is the sloppiest technology. Its just too bad that it isn't cost effective enough for cable and DSL to be delivered to the most rural of areas. Since these means of broadband have already been employed, they have a real track record and the limit of their rural reach is well defined. Being that BPL is almost entirely speculation, it is easy for its proponents to promise the world- since they don't have to meet those expectations at this time.
Look at the deployment costs for BPL. Either you (as the end-user)will pay super-big bucks for rural deployment, or you won't see it. Even worse, every customer of the utility company will bail the company out with increased energy costs. I don't think that the power line companies are motivated by charitable distribution of broadband to rural areas.
Let's hope for real competition based on stable technologies that will coexist cleanly with other technologies.
Wringing one's hands together at the signs of a hyped promise does not cancel out the salient arguments and concerns against it.
I just hope that your neighbor doesn't figure out that burning corn-based fuel in a noisy generator may create competition against the power company. The interference will probably be a by-product you will not quickly want to live with- competition or not!

| | | | Re: Oh No interference!! I knew someone would bring up meter-reading. BPL has nothing to do with meter-reading. Most, if not all, of the co-ops in Tennessee have been reading the meters via the connection for years.
A low speed connection is possible across powerlines, always has been. You do not have to bypass a transformer to get a reading off the meter. | |

Remote meter reading,while it's a new technique in some areas.Has been the modius operarandi a few years in my area.Now the only bad part of this equation is when/if the remote readers have a failure on either end.I inquired about that possibilty.The response to that is as follows:
The customer will be charged full kilowatt rate.The price I don't know as it's different from company to company,State to state..Here's the kicker.I asked why full rate and what is full rate?.? Since we can't determine exactly when it failed.We must charge full kilowatt usage.They couldn't?wouldn't? give me the price for full month kilowatt usage rate.Surely they determined a max x amount of usage.There must be an x amout of $$.Then what is cost of max x? Still unknown due to "to many varibiales"
Until we can determine your monthly kilowatt hours for an average.Then any money over charged will be applied in credit to the monthly bill.Doesn't sound very customer friendly to me.
Imagine, That may take a year? maybe two? to get cash paid. Back as an credit applied as a monthly adjustment.In another word the customer can take a screwin' on this.I'd prefer seeing the meter man/woman. | |

Shrewsbury, MA | Sounds like the last gasp attempt to justify a failed technology that couldn't escape into denial any longer and is now blatantly attempting to bulldoze its way through any legitimate opposition.
I see no need to justify the current state of Amatur Radio technology to self-styled "techies" - there is abundant reading material that would convince you otherwise, should you have the mental capacity to do the necessary research.
My justification to transmit and receive on the affected frequencies is clearly defined in Part 97. Similarly the limitiations under which BPL must operate are clearly defined in Part 15.
If the BPL industry is relying on shyster legal tricks to gain a foothold in the market (having apparently abandoned any attempt at selling itself on its technical merits - and who can blame it?) then it is indeed in deep trouble - such strategies are likely to be ponderously slow and we can all hope that BPL is left in its own legal dust as better technologies overtake it. | |

Hate to you but your wrong about the desire of this technology. Meter reading is taking place now over power lines without BPL. Of course BPL can be used for this but it is overkill for this app. But if you combine selling access and able to do AMR (Automatic Meter Reading) you just saved yourself a bunch of money. But BPL is far from being a workable solution and in time it will be come a usable product. | |

2) The city = FCC

1 edit | said by P Ness:So what is a little interference? let the market decide which service is more important.... If there were no other means to deliver broadband, and BPL could actually live up to the misconceptions its promoters create and journalists repeat (i.e. Internet everywhere there is a powerline, cheap rural access, faster than cable and DSL, etc.), you would have a halfway valid point. But the truth of the matter is those misconceptions aren't reality.
Most microwave ovens tend to play well with other devices in homes because of regulations that ensure electromagnetic capability. BPL is the only broadband access method that uses regulations intended to allow spurious slop from electronics devices (which keeps manufacturing costs reasonable) as the foundation for its entire existence. As such, it will always be at odds with and at the regulatory mercy of licensed wireless services, due nearly entirely to the FCC's poor job of understanding BPL and blindly promoting it in the name of competition. Competing products and not wireless spectrum regulatory policies should be sifted out and determined by market forces. | |

Customer Take Rate: 30%
Backhaul cost: $1k per month (a T1)

200kbps at DSL prices? What a joke! | |
|

While the hype they put out is the miracle to all, I remember when cable use to make the same waves. But everybody in the industry has limits that they put on themselves.
I don't see this as a miracle for broadband. Sure it sounds good because everybody has power lines, but don't we also have phone lines, and where is the old comment 'well if you have phone lines then you'll be able to get DSL'.
If this did catch hold do you really think they'll even consider going into rural areas for the first 5 years of deployment? 10 yrs??
If this did go full force it would start in cities, with high population where there is already choices for broadband. | |

1 edit | A BPL test I want to see.
What happens to a home receiving Internet service via a BPL modem that connects to a home computer.Using high-speed signal arrives at a "bridge"or "tap" mounted on a nearby utility pole and goes into the home through a special electric meter.Were that bridge or tap to fail.?
How many volts will suddenly be available at every single wall outlet in the house.? Me not knowing that much, would say you house suddenly goes "poof" into flames.As it's only one ten wiring.I say all your 220 wiring,appliances,circut breakers won't take that incoming voltage as well.
That is the test I want to see run a few dozen times to ensure safety.I think BPL needs 11,000 volts or more to live up to its promises.Not 100% sure on that.To have that much voltage in the event of a bridge failure.Me thinks one would be lucky to get out alive.
Will one need to wire one's house with 3phase electrical equipment? | |
|
| | | Re: A BPL test In theory, your main breaker would fail, saving your house.
The wiring of BPL *should* use a much lower guage wire to step down from behind your transformer to your home wire. That will offer some protection, dont know how much tho. | |

Mechanical breakers can't react quick enough and lower wire guage won't help as it would deliver the high voltage with enough current capacity to destroy anything connected to it.
However, personally I think the danger from bridge failures is not much to be concerned with. I think failures will be few and far between and if BPL ever takes off, it will be using a wireless last 100 feet (like Amperion) or be just on the low voltage side (like Motorola). | |

| | To the Ham radio backers. Try getting over it. Even assuming that the interference issue is real--which I've seen no solid evidence of--BPL technology is simply more valuable than Ham radio.
Sorry, but sooner or later old technologies die out, and you'll no longer be able to drive your horse and buggy on the interstate highway. If your argument is "This is the way it was before," then I'd have to point out that progress doesn't work that way. Show me a real, tangible benefit that Ham radio provides to modern society, on the level of broadband internet.
Yes, BPL may not be practical, yet. But this is first generation technology, and will certainly never be practical if it gets killed for the dubious benefit of a technology that the internet itself rendered largely obsolete years ago. | |

Minas Tirith | I'll accept BPL if - If it didn't interfere with other services [I'm not even counting HAM's here].
Using plain physics: it radiates on other frequencies and these frequencies are used by the government, aircraft, public service [police, fire, ambulance] and HAM's. One signal meets another signal on the same frequency and they interfere with each other.
Now, it seems like some people want BPL/broadband no matter what. Since it radiates on the frequencies of the services list above - the possibility of interfering with them (even though it has not, in all the trials) is there. Do you want it on your conscience the using BPL has - caused a death because a ambulance couldn't get directions, a police car couldn't get directions to the scene of a crime, or the worst, a plane coming in for landing couldn't understand the tower and makes a left turn instead of a right and crashes, possibly into another plane.
If you want BPL, even though it may cause these accidents, you need serious help, in my opinion. | |

| | BPL interference had been ironed out already !!! re: »news.com.com/Broadbands+power-li···g=cd.top
But policy disputes and expensive failures largely have been the hallmark of BPL. In 1999, for example, Nortel Networks, a telecommunications equipment maker, and the British energy company United Utilities abandoned a two-year BPL project.
Because BPL uses the radio frequency signals sent over medium- and low-voltage AC power lines to connect customers to the Internet, it can cause interference with HAM radios and emergency radios. Power lines, it seems, are great and often overpowering antennas because of their length and height off the ground.
In 2004, the FCC released a set of rules governing the use of BPL to prevent interference. Most BPL equipment deployed today keeps to these limits.
"I think the issue of interference has been a little overblown," said Bob Gerardi, manager of power line communications for Duke Power, based in Charlotte, N.C. "Some of the first-generation equipment had some problems, but the latest technology adjusts the power levels to avoid any interference."
With many of the technical issues ironed out, BPL is slowly getting deployed. More than 50 utilities across the country are looking into it. Duke Power, along with Progress Energy in Raleigh, N.C, and Consolidated Edison in New York, is one of three power companies currently in trials with EarthLink.
Duke began its trial with 500 homes and plans to launch a commercial service to 10,000 to 15,000 homes by the end of this year, said Gerardi. The company, which will rent access to its network to ISPs such as EarthLink, said it will be able to handle high-speed data services at 512kbps to 5mbps, along with voice over IP services. The cost of the service will likely be about $30 a month. | |

Since 9/11, we haven't had another terrorist attack here in the NYC area. Although that is comforting, I don't think that the threat is less real. (Of course I am not equating BPL and the horrific events of 9/11, but you get my point.)
I would also not assume that because the BPL provider denies any instances of interference, that this means that there wasn't. I don't mean to paint them all with the same wide brush, but several BPL providers clearly played with the facts and figures in their favor.
Furthermore, I don't hope for a plane to crash before folks will agree to look at the concerns related to the propagation of RF across unshielded power lines.
Be well, Rob | |

=====================
It`s more than a year now... no airplanes collided or crashed flying above or emegency calls being blocked by BPL in Current`s BPL service areas !!!
Current Technologies version of BPL does not use HF frequencies!
It uses carrier frequencies in the 30-50 mHz range which
still may cause interference to lo-VHF *licensed* services
such as the State Governments including State Police agencies.
Additionally, your logic is faulty. Just because something
hasn't happened so far doen't mean the potential of it
occurring somtime in the future are nil.
After reading the number of un-informed and ill-informed
posts in this thread, I am both amazed and appalled at the
ridiculous arguments some of these so-called BPL proponents
are asserting. (Oops, sorry, that word is probably not in
many of your vocabularies). Opinions are cheap and everyone
has one. Try basing arguments on fact and using logical
deductions to make your points instead of spouting an
ill-conceived "opinion" as fact. | |
