I suppose a report with hundreds of pages indicating that BPL causes interference to the radio spectrum doesn't mean that any actual interference really occurs either huh?
After all reports on paper dont cause radio spectrum interferance, BPL does.

Well, The bigger ther report, the more accurate and TRUTHFUL the data will be......
I suppose if the report had been 1300 pages, there would be only ONE HALF of the expected interferrence from BPL..
MORE GOVERNMENT HOGWASH !!!!

The interesting thing is that there is one BPL system that was developed in California and operates well above the HF spectrum, reportedly does not cause any of the RFI problems and really works, and it is seemingly being completely ignored in all of this.

In the same report, there is a slide that warns about problems with BPL, but it was "whited out" like the CIA "blacks out" information that they don't want made public when obtained by way of the FIOA. It's really kinda sad how the FCC simply refuses to accept the laws of physics. Fortunately, I seem to be hearing of BPL trials throwing in the towel almost as often as I hear about upstarts. Once the shareholders understand how expensive of a proposition BPL really is along with it's profit (?) potential, they jump ship. I've read that the BPL equipment needs a repeater on the order of every 1000-2000 feet. Just how many electric companies are willing to spend money on hundreds of repeaters just to reach a dozen or so farmers of which *maybe* 2 or 3 will sign up? Cable and (especially) fiber-optics are truly the only technologies I can think of that has the best potential to serve the rural customer. Satellites are in the game as well, so there is plenty of broadband hope for the masses without having to pollute -any- radio spectrum.

One can download the reports in their entirety from the FCC ECFS, but there are 25 files. They consist of a combination of Power Point slides that were an internal report between the FCC Lab and the FCC DC OET staff, plus about 500 pages of correspondence between the FCC and the complainants in a number of BPL cities.
To make it a bit easier for some, the following URLs may prove easier than the ECFS:
http://www.arrl.org/~ehare/bpl/FCC_Reports.pdf -- 25 MB, just the FCC reports
http://www.arrl.org/~ehare/bpl/FCC_All.pdf -- 50 MB, the reports and the correspondence
The FCC tests show that BPL is strong along long sections of power line; that BPL will degrade spectrum near BPL systems by 30 to 51 dB or more and that notching is only about 25 dB, leaving the amount of degradation that ARRL and others have measured in the supposedly "fixed" spectrum and in one that BPL was strong enough far away from the connection point that the FCC noted that notching in one system was inadequate because the BPL manufacturer "forgot" to notch one BPL coupler 0.7 miles away.
The correspondence shows that BPL interference is very much a reality and by all the back and forth, the attempts to fix it were generally unsucessful in those cases reported to the FCC, even with the FCC nicely asking the BPL operators to fix it.
I am still going through all of those pages and finding the technical details that essentially show the same things that ARRL found in its testing.

"Redacted" is apparently gov't legalese for "if the facts don't fit the theory, then change the facts".

At some point when the violations become excessive, the ARRL along with ham radio clubs and individuals will have a nice body of evidence to support upcoming legal actions. Maybe the FCC will see this coming and will put a end to it.

All i can say is negitive information scares off investors. And i would say this counts. Without investors a project has little to stand on.

THE WHOLE POINT IS THEY KNEW IT WAS A FLAWED SYSTEM.and yet they passed it ANYWAY. common sense tells us if a system is that BAD AS THOSE REPORTS SHOW they the F C C should have never PASSED IT THRU.it just proves to us once again MONEY TALKS AND COMMON SENSE WALKS. so hopefully present technology and future technologies WILL BURY B P L for good. 73 TOM.

Here's a link: http://mrtmag.com/mag/radio_technologies/
to an interesting article regarding BPL (last article on page). I get the paper MRT mag at work, and just read the story last night. Thought some here might find it interesting...
