Author missed an important point

The author failed to mention that BPL is convtroversial in that it causes interference with many other services, such as amateur radio. BPL is noisy and does cause interference to other applications that are RF sensitive. One website to mention: http://www.arrl.org/tis/info/HTML/plc/index.html

No, not really...

"Adoption has also been slowed by technical hurdles. For example, the technology has interfered with local emergency radios and Ham radios. But experts say these issues have been worked out and that interference is no longer a problem."

It's right there, read the article again. Emergency radio I can understand, that has to be dealt with. But HAM? Gimme a break. HAM has been obsoleted by the Internet.

BPL a problematical solution

There are a few implemenations of BPL that don't have RFI problems, but more do than don't. Public safety radio, law enforcement, amateur radio, and others are licensed users of spectrum is specific parts of it, emphasis on licensed. BPL must operate under part 15 of the FCC rules, while states unequivocally that it must not cause interference with any other device or service. FCC rules say that a part 15 device that does cause interference to a licensed device or service must immediately be shut down. Yet in city after city where BPL trials have gone on, local fire departments, DPW's, or hams have informed the BPL operators and the FCC of flagrant violations, of being utterly blanketed by static, to no avail. One can only hope that the new FCC head commissioner will take his role as guardian of this limited resource (RF spectrum) seriously, intead of being a cheerleader for BPL like the previous one was.

Additional Expanded Advantages of PowerGrid Broadband

Advantages of this technology are not restricted to those defined in this article. The most impressive advantage is that when implemented, it will immediately support “smart” home appliances and commercial devices that can easily communicate interactively through their power supply. Consumer product companies could send interactive operation instructions to devices or display menus on microwaves and other home appliances. Service and application companies could remotely control or monitor devices from a central location. This along with an unlimited variety of other new and developing technologies provides a path to our technological future.

The unlimited potentials of this technology will undoubtedly push the technology beyond any constraints, either technical or legal. The only real issue is how long other existing Internet Provider technologies can lobby their state governments to postpone implementation with regulatory restrictions or other means, for pricing will certainly not be a long-term issue to the well-established power grid.

What a new world we live in…

Advantages but also intrusion...

Yes, the advantages seem exciting but so do the privacy issues... disturbingly. With other broadband we have firewalls, masking, some means of some obscurity. Yikes, no privacy whatsoever? What if you have a camara system? Could someone override it to take pictures of you? You might say the telephone doesn't provide privacy, but I say we don't have to have a telephone. Electricity? Hmmmmmm...

re: privacy issues

In my opinion privacy is not an issue. This is like saying if you have windows in your house people will be able to look in at anytime and see what you are doing.

You can put security in place and unplug/switch off devices you are not using. No more problem.

about BPL

slapmonkey? How apt! You haven't been hacked through BPL as I've been hacked for over a year now and no police agency can or will help me. Perhaps it's becauise they're the ones doing it and I'm not doing anything illegal. Only trying to port a financial database to the Internet to help retail investors do their own research on stocks and avoid the 'buy & hold (my bag of excrement)' inducements of stockbrokers. Slap yourself for me, monkey!

What about the rest of us

Once again someone comes along offering broadband to the masses. No mention of the rural folk. Why on God's Green Earth would someone with access to dsl, cable or wireless even look at BPL?
What about the millions of folks that are stuck with antiquated analog dialup? Gimme a break.
Develop something with the rural folk in mind.
Big Brother is watching you. That's the biggest copout of the century. If they want to check up on you they will with any means necessary.

Interference no longer a problem...

...Suuuure it's not- Move to within 100 feet of any power cable with broadband pumped through it and try to do -anything- with any Ham radio band.

With 1500 watts of rf moving through an un-shielded cable, you'll love the effect on cordless devices as well- Everything from wireless mice to cordless phones.

The next disaster, you better hope that the power lines fail completely if you need Ham radio operators' help.

It's Not a Problem According to This

It's not a problem. Check out this website for more info:
http://www.broadbandhomecentral.com/report/backissues/Report0405_4_pf.html

The key paragraphs are:
----------
Al Richenbacher of PPL reported on the experience gained from its extensive BPL trial in Allentown, Pennsylvania. He said that PPL's BPL system now passes 6000 homes, and over more than a year they have received complaints from only four hams.

PPL has tested several different BPL technologies. All provide capabilities to avoid the use of ham frequencies--either by moving specific bands in the spectrum, and/or by "notching" to avoid the use of those bands. By using these techniques, PPL stopped interference on the ham bands. After PPL made these changes, two of the four hams said they were "pleased" by PPL's response to their complaints -- and three of the four signed up for the BPL trial!

He observed that an electrical utility deploying BPL could take one of two approaches to avoiding interference with ham bands: responding to complaints by moving or notching specific bands, or by notching out all of the amateur bands in advance. PPL has chosen the latter proactive approach and does not expect to receive any complaints
----------

I'm sure that if garage doors, wireless mice, etc. were negatively affected, I think even the ham radio operators may have complained about that as well.

BPL sounds great to me, and I think it's only a matter of time before it gets widespread just as cable broadband took time. With some serious P.R., rumor control, less expensive equipment, and competitive rates, I think BPL is only headed for greatness.

Already Using This.

I am already using this technology. Bought Powerline Adapters for my home through CDW.com and it works very good. I have a cable broadband into the house, and then using one of these adapters, I can plug my desktop in any room without having wires or a signal problem like I have had with wireless in the past.

Glad to see they are making headway on this.

[FireWatch]

Already Using This? Not Really.

What you describe (cable MODEM with adapters to feed the MODEM signal through your house) is not what is at issue. This small system contained inside your home is comparable to BPL like a childs model rocket is to the space shuttle.

BPL is carried on the service lines through your neighborhood. It operates at higher power levels than your home system. Since it typically operates in the HF frequency range, it also has more of a chance to find a resonate length of wire to act as a broadcast antenna. It can and does cause interference even with less than ideal lengths of wire. Since it is an FCC part 15 device, it "may not cause any harmful interference to any liscensed service" and furthermore must accept any interference from other sources including interference that causes undesired operation.

I urge you to do more research from the perspective of the Amateur Radio Operators (Hams) before lauding too much praise on this current version of BPL. That said, there are companies doing research on BPL using frequencies which cause litle or no disturbance to the frequency spectrum.

Rural Areas

Yes I hope they will expand BPL to Rural Areas who are left with no other alternative but Dial-Up(or Slow Expensive Satellite) before Areas with many options...

Although I live in Kentucky ,I hope they expand BPL here first since Cinergy provides service here(close to where I live in Kentucky anyways) and is based not far from here(Cincinnati, OH)...

watch for tornadoes

I think a lot of storm spotters use ham radios to relay storm reports. So keep an eye on the sky. The hams may not care anymore. I really hope there can be a solution worked out that benefits everyone.

A HAM Radio Operator?s Perspective

Hi All,

I am a HAM Radio Operator (N0BIG) as well as a hardware design engineer specializing in telephony/communication design.

HAM radio traditionally was/is able to provide emergency communications in disaster situations where cellular and Internet based systems/infrastructure often fail.

What the WEB has done however is to greatly thin the ranks of HAM radio operators that are prepared to offer emergency communications in times of emergency. Being prepared for a disaster includes having generators etc. and other equipment that is getting scarcer and scarcer in the ?tool boxes? of contemporary HAMs.

When I first got my HAM license (In the late 1970?s) the ?social communication opportunities? afforded by HAM Radio was a major factor that attracted people to the ?hobby?. We were the original ?chat rooms? were people of very diverse backgrounds could hang and socialize. Where else (at the time) could you converse with the King of Jordan (Who was an avid HAM Radio operator.)

We spend billons of dollars for homeland security. A little money directed to encourage HAM radio to be more prepared for disaster response, would be money (IMO) very well spent.

Finally, technological advances in Broadband over Power Line technology is moving towards making the interference issue ?go away? as well.
