Yeah, but your over the limit! :)
Heck why go after a 3000 little guys when you can
go after one big guy.
They've been selling unlicensed amplifiers and
uncertified systems for
as long as I can remember. Heck, talk about
posting a message on this
list, what about having a full blown catalog
online advertizing US sales
with prices next to them?
I believe they should have spent the 3 or 4 g's
to get the systems they
sell certified before they sold them.
They make millions easily selling uncertified
gear and it's not a secret.
Ohh, I feel another rant coming on.. .George, you
better take a chill pill
:)
While this is a peripheral issue with
"certification", I have made
suggestions to the FCC about certification of
individual components. I
kinda doubt it's going to happen. At least not
soon, regulators are
notorious for not liking change, since it makes
things less tidy for them.
I buy computer components... motherboad,
processors, video cards, and so
on... And tires, and car parts, and actually
quite a few other things that
have technical performance reviews by people who
have tested things.
I WISH that manufacturers could certify
components, because then we'd have
published real-wolrd performance graphs and charts
to use for comparison
when we buy things. Just "certified" really
isn't "good enough" in my
view. I recall that a good number of years ago,
there was a hack for a
linksys AP that turned up the power. Someone used
an SA on it and found
that when you did it, the output became incredibly
dirty.
Certified or not, I would like to know that what I
buy is "clean" rf-wise.
Low OOB emissions. Minimal out of channel
emissions, selective recievers
that reject adjacent channel noise. Really
comparable specs for dealing
with noise and S/N ratios, etc.
I really dislike not knowing those things about
what I buy. And, due to
the way certification works, certification has
almost no meaning when it
comes to those important RF characteristics.
Early on in my investigating
the wireless business, lots of people were testing
new products and
publishing the results. I dont' see ANY of that
going on anymore.
Wrong. Certification DOES test for out of band
emissions; it also tests
for out of channel emissions. It does not test for
receiver selectivity
because that is not a characteristic that will mess
up the band. Part 15
certification deals primarily with dirty transmitted
signals, not poor
receivers.

Any suggestions to motivate manufacturers?
