Wouldn't it be possible to place a filter at your meter that would shunt
the BPL signal to ground for the whole neighborhood?

Isn't that a bit like asking if you short your phone line, can you knock
out all the neighbors phones?

Or, even better and more accurate, if you short your cable tv, can you
knock out all the other neighbors cable?

Geesh, I am glad I am not one of you guys neighbors. You guys obviously
live on the WRONG side of the tracks.

Just great, and then you wonder why the public at large considers
amateurs eccentric and absurd ... :-(

No, but one of the issues with BPL is that equipment connected to outlets
changes the configuration, and although BPL is adaptive, reliability of
full speed service at any location in a premises is not assured.

No. BPL signals are already filtered out by distribution transformers.
In order for BPL to work, there are relaying devices installed at the
transformer.

There are several systems for the last "100 feet" including WiFi type
systems.

Here in Isreal there was a BPL trial and becuase of the interference
to HF communication it was not allowed. Israel Electric took a different
approach and has wired fiber optic cable all along their right of
way. They use it for their own network, remote managment and monitoring
etc.

They can also use it for selling Internet service if approved, without
using BPL.

As for long distance wireless access, if WiMax ever reaches its claimed
potential range, it would be cheaper to install a MESH type WiMax network
on power poles. Not only would it provide rural Internet access cheaply,
it could be used to sell wireless Internet access to travelers with
handheld devices.

BTW, 2.4 gHz is not the only band for wirless services. I have several
DECT cordless phones which operate in the 1.8gHz band, interfere with
nothing, including cell phones which also operate here on that band
and have longer range than my WiFi devices.

The explanation depends on a particular deployment topology, but the answer
remains NO for other deployment topologies as well.

Probably not. But a couple of companies, including Motorola have BPL
systems that do NOT interfere with amateur radio services at all. The
problem seems to be getting regulatory agencies to mandate such systems
rather than the sloppy ones they seem to have been bribed to permit.

When money becomes the political power, then anarchy has arrived. Ultimate
political power in an anarchy is simply feudal. That is to say, whoever
can buy the most firepower eventually gets to rule. You either bow to the
feudal lord or he runs right over you with his army. Or you get a bigger
army of your own. Those are the only real choices and don't ever pretend
it's democratic because it's not and wasn't meant to be. Lacking an army,
your only real recourse is to divine right monarchy.

Read the ARRL's story on Motorola LV: 'Less than two years after
announcing its Powerline LV Access BPL product, Motorola has decided to
suspend product development and to devote its resources to more promising
markets, industry sources say.' Full story at
http://www.arrl.org/news/stories/2007/04/25/102/?nc=1 .

That is a reduction in focus on Access BPL, and the form with the widest
impact, but that is only one form of the BPL scourge.

Dave, perhaps what you see in me as pessimism is more realism, and it is
born out of working in the telecommunications industry, understanding the
carriage market and the challenges in competetive broadband delivery.

I have also measured BPL emission on the street, analysed measurements by
others and written / reviewed many reports on the impact of BPL
emissions. I have a good understanding of the impact, and the BS of the
'it won't affect me' justication of apathy.

The transformation of ham radio to the province of six hour hams with
their shack on their belt impacts the sustainability of ham radio. They
do not have the knowledge and experience, the credibility to challenge
the threat.

The 'it won't affect me' approach and redneck solutions help to divert
attention from the BPL problem.

BPL might crash and burn of its own accord, and I frequently see people
calling out the failure of a small BPL deployment as evidence, but in the
last few hours I have reviewed a report on ambient noise measurements in
an area for planned BPL deployment in the coming weeks, and the
implementor is no small naive power company business development unit.
BPL remains a serious threat.

Have you ever read, "The Sky is Falling", by Chicken Little? He/she
shared much of your same belief system ... read it, it may be worth your
time. :-)

Oh, I'm not downplaying it as a threat. It's just one more symptom,
though of what has gone wrong in our world. It used to be that "money
talk's; bull**** walks" was the adage. Now it's "money bull****s and
everyone else is supposed to bow down and kiss its feet."

There is a way to filter BPL from specific power poles. Its called a
chain saw.
