Scott,
I believe that your comments are substantially correct.
The main problem that I see with building our own equipment is that very
few (if any) manufacturers of modular wireless cards have certified them
with a range of usable external WISP-grade antennas. I don't think this
2nd Report and Order changes that. Also, remember that the software used
must limit operation of the complete system only to those frequencies
and power levels that are legal in the U.S.

I haven't read it really well and I have not yet looked up the
referenced sections of Part 15, but I read the part that is not about
"split modular" to be the part the refers to a PC. And I read it that
if the PC is certified to have radio cards AND the radio card is
certified with an antenna, then that PC, radio card and antenna can be
used.
So, if that is true, then Tim may be on the right track. Jack is right,
not any "base," but I would read it that any "certified base" is doable.
I have often wondered how it works for laptops, but hadn't bothered to
find it. This makes sense. Ubiquiti certifies the CM9 card with a set
of antennae. Dell certifies the laptop for a radio card. Putting a CM9
in Dell's laptop is fine as long as it connects to an antenna, using the
proper cable, that was certified with the CM9.
Therefore, if MT can get an RBxxx board certified as a "base" unit, we
should be able to use a CM9 in that RBxxx with the proper antenna and be
good. The "gotcha" here is those sections of Part 15 I have not yet
followed up on. I am not sure what the "professional installer" stuff
is about.
What am I missing or is this good news?

Tim,
I read the 2nd Report and Order and I don't see where it is saying
that a certified mini PCI radio can be put into any "base" unit.
I think what the FCC is doing is:
1. Providing eight criteria that clarify the definition of what a
legal modular assembly is.
2. Allowing some flexibility regarding on-module shielding, data
inputs, and power supply regulation.
3. Clarifying the definition of what a "split" modular assembly is.
4. Defining the (somewhat flexible) requirements that a "split"
modular assembly must meet.
Although a motherboard will certainly contain an operating system, I
don't think that a mini PCI radio plugged into any motherboard meets
the FCC's definition of a "split" modular assembly. I think the FCC
considers a "split" modular assembly to be where circuitry that today
would be contained on a single modular assembly is (now or in the
future) "split" between two different physical assemblies. This
splitting allows more equipment design flexibility because one
"transmitter control element" (the new term that the FCC formerly
called the module "firmware") could theoretically be interfaced with
and control more than one "radio front end" (the amplifier and
antenna-connecting) section.
Of course, that's just my interpretation. I'll bet others could add
more detail. The bottom line is - I don't think this 2nd Report and
Order contains anything that will substantially change the way we do
business.

Am I reading this correctly???? Does this mean that if a mfg of a
mini pci radio gets it certified with different antenna, that it then
can be put into ANY base unit and be certified?
Please correct me if I'm wrong, but isn't this what we have been
asking for?

All,
I just received this document and thought it might be of some
interest to the list.
