| Wow, the list of UTILITIES AND STATES for BROADBAND POWERLINE goes on and on. I was surprise to learn that there were lots of companies interested in the new technology. It seems to me that BPL/PLC is getting hotter than ever. Imagine the possibilities of a SMARTER GRID throughout the country and the same time offering a HI-BANDWIDTH, HI-SPEED SYMMETRICAL BROADBAND ACCESS speed for triple-play services like STREAMING HDTV, VOIP and DATA !!!
Remember that FCC classified BPL, CABLE,and DSL as information services !!!

Burlington, CT | said by BPL 200mbps :
Wow, the list of UTILITIES AND STATES for BROADBAND POWERLINE goes on and on. Yes, there are more systems listed on ARRL's page than on the UPLC page. The League's page is, however, presented accurately and honestly, with the successes and failures all listed in a fairly unbiased way. I don't think that we will ever see that from UPLC.
If you are going to comment on the ARRL page, though, I might suggest that you follows its lead and not be selective in your observations. There are a few utilities listed there that are considering BPL, but there are also ones like PPL and IDACorp that abandoned BPL cold. PPL was deployed past about 10,000 homes, but pulled the plug. IDACorp spun off IDACom, then abandoned its interest. IDACORP announed that its foray into BPL cost its stockholders about $10M.
You can also note the number of reported interference problems with BPL. Although some companies are actively working to address that, others are apparently not.
At one of the BPL-industry events, I gave a presentation on BPL from an EMC point of view. In my introductory remarks, I noted that the things that the BPL industry is trying to accomplish are good things. It is just a question about whether BPL is the way to do it. Trying to put high-speed data onto wires that were never designed to carry it -- in fact whose characteristics are such that ingress, egress and noise are inevitable -- can be made to work, but the long-term reliability of that approch has not been proven and has, to date, been fraught with technical difficulties, if the reports I get back from some of the BPL implementers are any indication.
It is natural that utilities would want to use their own wires to control the grid. That doesn't require high data rates, however, and as PPL is doing, that can best be done at lower frequencies, with slower speed, on spectrum where the FCC rules, at least, have no specific requirements.
It is natural that consumers would want higher data rates, but everything that DS2 chipsets can do on MV distribution and premise wiring can be done even better on conductors whose characteristics are actually controlled and whose characteristics are optimum to send radio-frequency data signals considerable distances.
BPL is trying to combine both worlds into a single platform. From an economic point of view, that could make sense, but it remains to be seen whether the technological issues that go along for the ride justify the balance.

| Were Idacorp and PPL using SLOW first generation BPL that has no notching capabilities like DS2 2nd generation 200Mbps BPL chipsets?
It seems to me that newer BPL technologies are on the rise and adopted by prominent utes out there.
No matter how you NEGATIVELY spin the BPL SECTOR, UTILITIES are on the pursuit of ADVANCED SMARTER GRID, no matter what to protect their investment- aging powerlines-.... imho.

Burlington, CT | said by BPL 200 Mbps:Were Idacorp and PPL using SLOW first generation BPL that has no notching capabilities like DS2 2nd generation 200Mbps BPL chipsets? Notching existed in the 1st-generation chipsets, too. It was not as good as the present DS2 chipsets, however. Among the companies that were being trialed by IDACorp was Ambient, the same company that has been unable and unwilling to correct the BPL noise on the Amateur bands in Briarcliff Manor, NY.
No matter how you NEGATIVELY spin the BPL SECTOR, UTILITIES are on the pursuit of ADVANCED SMARTER GRID, no matter what to protect their investment- aging powerlines-.... imho. To most in your position, anything positive about BPL is news and anything negative is spin.
It is the "no matter what" that really outlines the agenda. Irrespective of interference, there are some in your industry that claim that the benefits of BPL warrant any negative consquences. The result of that has not been good for anyone, including your own industry.
It only takes a quick perusal through the links I provided to show that a signficant number of utilities have tried BPL and decided it wasn't a good idea. Radio interference has probably not been the major factor in those decisions, however. I sure hope you don't consider that to be good news, because had inteference been the major issue, there would at least be some shot at correcting it.
PPL, for example, announced that its base of 1.2 million customers was not large enough to economically support BPL. IDACom announced that the economics of BPL just didn't work, or words to that effect.
Of course, that was all "old" BPL, and this time, BPL really has overcome all of its problems and there is not a single thing that will stop it now. Unlike 2002, 2003, 2004, 2005 and 2006, this time, 2007 really IS the "Year of BPL." 
If you really want to see BPL be successful so your investment can pay off, help your industry follow the successful models of the cable industry, the DSL industry and others and work cooperatively with licensed radio users instead of calling everything they say "spin." Had the BPL industry done three years ago some of what it is doing right now instead of groups like UPLC making ridiculous claims like "BPL will be inaudible," then it would be steps ahead of where it is today, IMHO.
Now, if you want to talk about spin, hold your words up to the mirror and see if you think it would be fair if I were to say just the opposite. Anything that is truly fair still looks fair when seen in a mirror...
