Broadband over power lines is now being rolled out in Manassas Va.
This is a very lucrative technology, but it also appears to be a very noisy
technology, radiating noise from a couple MHz through low VHF.

Believe it or not, even CB radio is supposed to be protected against this
sort of interference.
At least the FCC is supposed to act on well grounded complaints by a primary
spectrum user, against interference caused by other primaries, secondaries,
and part 15 devices.

Is the Manassas BPL a test model, or can it be implemented by any
municipality?

ps- cool sig

I don't know yet, but it sounds like it's rather larger than the test
systems that have been implemented previously. The power companies are
claiming that this isn't causing interference, but if you go to the ARRL
site, you can watch movies of field observations where the energy radiated
is wiping out pretty much the whole HF spectrum.

Thanks

Somebody with no common since is getting paid off for this kind of ****
going through.
BPL has not worked that well in other countries and in some places it was
taken out.
There is better ways for connecting to the net anywhere, and its not BPL.
Just like HDTV is being forced on to the Public
and the FCC is counting on making BIG money on the spectrum after the
Analog TV stations give up their allocations. It all comes down to money.

I may be wrong but isn't BPL's implementation limited. Doesn't BPL
have a low enough bandwidth that it is only practical in rural areas
where it doesn't have to service to many customers from the same
power line?

Depends how they set it up.
Broadband on cable is limited too, but they do it as "neighborhoods", rather
than trying to feed the whole thing from the head end. I expect the power
companies will roll it out anywhere they have enough potential subscribers
to justify the cost.

I think this is at least one point, where hams and CB folks have solid
common cause.
