Analysis by Andy Sennitt, 21 October 2004

The US Federal Communications Commission (FCC) has given the thumbs up to
the development of Broadband over Power Lines (BPL) technology, which at
first glance looks like bad news for existing users of shortwave such as
international broadcasters and radio amateurs. But based on what US computer
industry analysts are saying, it looks as if BPL might not be as big a deal
as first thought.

Yup, if the FCC says no problem that means no problem - and of course
the computer industry has given much thought to the impact to existing
users of the RF spectrum .......... NOT.

The FCC is responding to a cash call for the power industry, the
computer industry sees an expansion of the market so they too will be
in favor of it. To many of us though it is just going to be another
[possible] QRM source. Those who live too far from the phone exchange
for DSL have other options, namely cable - and for those without cable
there is satellite service (DirecTV has offered this for a few years)
so it isn't like there aren't other options. There are enough
problems with our power grid as it stand without adding BPL to the
already stressed infrastructure. I fear your excitement, while
sincere and well meaning is misplaced.

Doesn't look like you read the articlegrin...

The article doesn't suggest BPL doesn't cause ruinous QRM.

What it does suggest is that BPL is not a financially viable technology,
and that rapid improvements in wireless technology have superceded it.

Indeed, BPL installations in several places both in the U.S. and
elsewhere have already failed for financial reasons.

Doug,
Did not fully read it - mea culpa. Did catch the part about it not
being financially viable though. Part of what you saw was my bad
attitude in general yesterday, as well as my general belief that the
FCC truly hasn't taken full consideration of the BPL effects to other
services.

Peace,
Howard

Just wait until they fire up a BPL injector in your neighborhood and you
have to try and listen over the top of the noise those things generate.
You can forget using 2-80 Mhz within a mile of one of those injectors

Leakage happens in both directions. I think there will be no problem
using 2-80 Mhz near BPL systems. In fact, I recommend everyone set up
a kilowatt beacon on 10M as close as possible to them. I think the
problems will be for the poor sods trying to get the hopelessly
ill-designed system to work as much as anything else.
