K0HB:

I just love you guys, now you have me claiming that I know how it is going
to all work and am a "hardware authority."

Only homebrew here is linears, antennas, swr meters, and various other
"little projects" (and yes, I know, my SWR meter actually measures the
proper loading of the transmitter and NOT real SWR--but hey, I think they
keep my finals running a LOT cooler--kewler too.) Line radiation, take
off angle (because of mismatch), and increased losses don't give me
nightmares anymore.

NOPE not me, I am a software engineer (I like the title "White Hacker"
better, coder has a "ring" to it too.)

Read my past posts, I say the hardware/software guys working on BPL have
some ideas to check out, they are doing that now. If it is feasible it
will come to use, if not, it too will go the way of the dodo bird. I am
saying any number of "authority hobbyists" which don't know a fifo, lilo,
circular queue, linked list, doubly-linked list or binary tree from a
banana tree don't count. And, most likely, don't even have the beginning
of knowledge to make a statement on its' feasibility.

On RFI, they are collecting data, re-thinking, re-engineering and
re-working algorithms--after "real world data" I would imagine testing
will move indoors and be done in software--mostly... I will take a look at
the data--when it has been explored throughly (well, I might not, not that
interested really--if there is noise I will know it.)

But, your argument seems to me that you are more qualified and
knowledgeable and should be telling them not to even bother, go tell them,
see what they say... I am telling you, I know better than to do that!

You feel somehow a group of idiots got in charge of BPL and no one is
noticing, I think you are wrong. If my past experience is any indication,
they are the very best designers, R&D people, engineers, mathematicians,
etc. which have the confidence of the industry, that it should at least be
investigated.

But, what do I know? Maybe they got three mexican laborers--one with a
wire, one with a calculator and one with an old TV they are going to use
for parts. Hey, ya never know!

Too bad they didn't consult with arrl and you--would have prevented them
from looking like the fools you claim and expending uncounted bucks!
Yanno, someone save them that kind of money, they might consider making
you their CEO! Maybe it isn't too late!

I am saying, data compression will be the real key in the end, no
matter what the medium of transmission... and I do know that! It will be
the guy which knows the difference between a binary tree and a banana
tree...

300,000 with a 10:1 data compaction is already at 3,000,000... due to the
fact we KNOW NOTHING of the data compaction methods they are using (most
likely trade secrets) we can't even guess what they are capable of... I'd
venture 10megs or more...

You guys seem to think in terms of brass keys...


You think way too small, John (if you've even thought about this at all).

A single subscriber just might (doubtful, but maybe) be able to be served via an
under-300KHz pipe at xDSL-like speed (which is decidedly slow by comparison to
other "broadband" delivery options available).

But we're talking about scores of subscribers (maybe hundreds in a high density
housing area) sharing that power-line "trunk". Every BPL scheme that I've heard
about extends from around 2MHz up into the low VHF range at 60MHz or higher.

Take the time to examine the technology before you embarass yourself more.
