BPL providers, we are licensed...

It's not that simple.
At present we have protection against non-licensed users including
BPL. When it becomes uncomfortable for the BPLers, they will
petition the FCC and with enough "juice" applied, the situation may
very well change 180 degrees as to who has to protect whom.
The protection that the Rules grant can be reversed at the stroke of
a pen.
Correct.
Do you have any idea how the rules might be rewritten so that they
exempt BPL, but don't apply to every other unlicensed service?
BPL isn't an unlicensed service. It's an incidental radiator - under present
rules..
Correction noted. It is still regulated under part 15 though, yes?
One simple change that could happen would be to define BPL as a new class of
service - perhaps with a "license" of some sort.
THe act
of unlicensed services given carte blanche to interfere with the
licensed ones would indicate that they can interfere with other
unlicensed services!
(Insert standard "not a lawyer" disclaimer here)
Who defines what constitutes "harmful interference"?
Just wait until some intermod interferes with a baby monitor at the
wrong time! Guess Mr and Mrs Smith will be consoled that their neighbor
can download his porn via protected BPL.
Not a question of intermod. And since the baby monitors have to accept
interference today, they'd not be protected anyway.
BPL is susceptible to intermod effects is it not? I'm assuming that if
it is at different frequencies, that the frequencies can add and
subtract just like other RF.
Besides, it would be a simple matter to notch out a narrow band around 49 MHz
for old cordless phones, baby monitors, etc.
Except for that intermod problem, which would get to you via the
"incidental radiator"
This is the opening of a brave new world of wonders! Just imagine once
those pesky "regulations" (a swearword in republicanese) go away.
Just the next step in "getting the government off your back"...
Those cheap Chinese TV's will be a couple bucks cheaper once they can
get rid of that stupid RFI shielding.
The same for computer monitors. Those sissies that are worried about
monitors pooping all over international distress frequencies can go take
a hike. The need for another broadband option and the needs of the many
far outweigh the needs of a crashed pilot. Hell he or she knew the risks
when taking off for that flight.
There are people who will argue that point.
What amazes me is that there are some people that will agree with it!! 8^O
So many electronic items can be made cheaper by removing those stupid
interference regulations, it is a wondrous thing. The free market rulez.
Sort of.
Consider that for many people today, "radio" below UHF almost doesn't exist.
They have broadband internet (wired), cable TV (wired), cell phones (UHF)
satellite radio (UHF), maybe a wireless lan (UHF) etc. Heck, conventional NTSC
TV is supposed to be replaced by digital HDTV a few years ago, etc.
Somewhere along the way, people will discover that *nothing* works
anymore tho'. ;^)
Nothing *old* works anymore. The solution will be simple: Go buy a new one.
(Made guess where).
That shouldn't matter. Buy a new unshielded device to replace the old
unshielded device. Same problems and more. There really is only so much
spectrum to use
Look at the history of consumer electronics since the '70s, Mike. LPs were
replaced by CDs. Beta was replaced by VHS which is being replaced by DVD in a
bunch of formats. (Remember the big old laserdiscs?) How many generations of
computers and various hardware formats have come and gone? Etc.
I have to live with the problems caused by that. When you have to
archive digital data, the disappearing machine paradigm causes us to
have to re-archive, and re-archive and re-archive. Coupled with the fact
that CD's are now considered to be extremely non-archival, it's a
nightmare, or at least almost a full time job for someone!
Our Ford had a phrase for it: "ending is better than mending"
This isn't anything new. More than 40 years ago, the major car companies knew
that, on average,a large part of the new-car-buying public was buying a new car
every 2 model years. Their goal was to get it down to every year. Back then the
average car lasted about 7-8 years, and it was a rare one to go 100,000 miles,
but the manufacturers paradigm was that it was better that way.
And now (most) Automobiles cost so much that people have to take out
longer and longer term loans. I know people that have 7 year car loans!
This new paradigm is near it's endgame also. I note that the local car
dealerships are filled to bursting with those 35-40 thousand dollar cars.
