Mark,
Certification verifies that the signals conducted into the power line
and the signals radiated into the air from a wireless system are clean
and that they do not exceed the power limits. Minimizing self
interference is primarily a function of good network design techniques.
This is outside the scope of FCC certification because, even with
certified equipment, it is easy for an uninformed person to deploy a
network that interferes with itself and with other networks.
To motivate manufacturers, let them know you want to buy only certified
systems from them.

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.

Well, I should have been more clear. Yes, there are tests and certain
limits. Just being "good enough" isn't what I was wanting. I'd like the
best stuff, because doing so means you minimize self interference, etc.
Any suggestions to motivate manufacturers?
