		BPL modem speed, like cable and DSL modem speeds, is changing rapidly with each advance in new technology, so it would be difficult to make any generalization here that would be accurate or timely.
		BPL modems that electric utilities and their service partners can install on the electric distribution network also are available now.
		When BPL modems are installed on underground electric lines, the communications signal is shielded by the conduit and the earth and as a result is unlikely to cause interference to other communications services.

	BPL NOI Comments
		By moving swiftly to examine BPL and to establish appropriate rules for its use, the Commission can provide this emerging industry with a solid foundation upon which to build new services and products that will benefit American consumers and businesses.
		In tailoring its rules to promote BPL deployment, the Commission must be certain to provide all communications stakeholders with adequate protections against BPL emissions that may cause unacceptable radio frequency interference.
		The repetition interval of the BPL signal will be determined from the operator’s technical data that describes the BPL signal.

	Frequently Asked Questions About Broadband Over Powerline (BPL / PLT)
		BPL vendors may claim “new technology” and advances have now made it possible, but the fact is they can’t change the laws of physics.
		BPL proponents reject this as being too costly, but that would be the cost to make this a real viable technology.
		BPL is a radio signal on the powerline, and basic electronics theory states that any unshielded conductor a ¼ wavelength will radiate RF energy.

	broadband » News » Broadband Over Powerline Astroturf - 'Big Year for BPL!' cries PR firm
		BPL opponents haven't needed to astroturf to make their case: the Florida hurricanes of last summer and the recent tsunami in Asia have demonstrated the importance of HF communications, even in this age of cell phones and the Internet.
		BPL is not needed to provide more broadband or competition as the barriers to this are political, not technical.
		Though BPL is in its infancy with regard to deployment in the US, it is available in sections of New York City and, in what is the first city wide commercial BPL network in the US, the suburban Washington D.C. community of Manassas, Virginia.

	The Cincinnati Post
		Jay Birnbaum, Current's general counsel, said the agency appears to have addressed complaints from amateur radio operators who suspect that BPL signals are interfering with radio reception or transmissions.
		BPL operators must also be able to remotely manage and monitor their systems so that they can determine if they're the source of the problem, he said.
		The chairman of the Federal Energy Regulatory Commission also issued a statement on Thursday supporting further development of BPL, with minimal regulation, as a means of improving power companies' abilities to monitor and control their electric networks.

		Important issue: The database for BPL should include all complaints filed and the amateur community should have representation on the "industry-operated entity." There must be a requirement that the database be kept up to date with all new information submitted and reflected in the database within 5 working days of completion or complaint filing.
		Since the nascent BPL industry and the FCC are so sure that interference won't be a problem, they "should" be amendable to such an approach which would allow "the rapid identification and repair of malfunctioning units" or some such language.
		They didn't "turn up BPL in the city," it was a test for a few residents in a very small area, and it was NOT available to "all residents and businesses." There were no licensed amateurs (or other licensed users of the HF spectrum) located in the test area.

	BPL
		Because of the great disagreement between BPL promoters and those who stand to be impacted by the implementations of BPL systems, it seems that the Commission ought to be obligated to, at the very least, conduct some sort of real world testing of its own to determine the radiation characteristics of power lines.
		The coexistence of Access BPL with other critical uses of spectrum is not a goal to be achieved; it is a BEDROCK REQUIREMENT for operation under the non-interferences conditions of the Part 15 rules.
		To date, no thorough technical analysis exists that suggests BPL can be implemented in a manner consistent with the noninterference conditions of the Part 15 rules, and many analyses, as well as real world observation and simple physics, suggest the contrary.

	ARRLWeb: "BPL is a Pandora's Box of Unprecedented Proportions," ARRL Tells FCC
		In announcing its BPL initiative earlier this year, members of the FCC could barely contain their enthusiasm for the technology.
		Studies appended to the League's comments suggest received signal levels of BPL broadband noise at typical amateur stations would be anywhere from 33.7 dB to 65.4 dB higher than typical ambient noise levels in the worst-case situations.
		The ARRL concluded by urging the FCC to ensure that BPL "is not permitted to operate in or near any Amateur Radio allocations" and that any future changes in ham allocations would "trigger retroactive modifications to BPL facilities" to avoid amateur frequencies.
