BPL in the News - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2010 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

NOTICE: The original RF Cafe Forum is available again for reading, and the new RF Cafe Blog is an active board.

Greetings:

A couple days ago I saw an article address the RF energy that is leaked off of power lines when the BPL (Broadband Over Powerline) scheme is used for the "Last Mile" solution to proving ubiquitous Internet - as well as for implementing the Smart Grid.

Now, there are proposals to actually license portions of the spectrum specifically for BPL. It seems to be tantamount to an admission that the leakage cannot be controlled.

:arrow: Do smart grids need special spectrum?

BPL interference has been a concern for Amateur Radio operators, and they have been on the front line in the fight to either prohibit the practice altogether, or to strictly monitor and control it. Even after the initial installation is qualified, equipment degradation and system modifications are not as tightly controlled so the potential for excessive interference is great. Enforcing compliance is typically much more difficult that initial conformance.

Oddly, there was also recently another article that claims since the BPL frequencies are primarily above 30 MHz, the interference with most heavily used Ham bands will not be affected. Supposedly, the author of the article verified that with ARRL HQ. I tried to find the article - probably on one of the engineering websites like EDN. It was just a couple days ago, but I read so much stuff that I can't keep track of it all. If I find it, I'll post the URL.

That statement does not comport with recent chatter on the ARRL website.

:arrow: FCC Continues BPL Debate

:arrow: It Seems To Us: Now We Know

Interesting related article:

Here is a recent IEEE article on Smart Grid progress

Hi Kirt:

Every Ham knows that the FCC will turn a blind eye to the BPL violators, because there is lots of $$$ to made off of selling access to power lines, but not much to be made off of Amateur Radio. In fact, the FCC would love to be able to auction off our protected bands. If that new FCC Diversity Czar (Mark Lloyd) has his way, we'll lose our privileges of free speech like what's happening in Venezuela under Chavez (see Lloyd praising Chavez's state-run takeover of media). :smt076

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
