Is there any document or other source that explains how the requirements &

Barring that, I believe members of this list participated in that standard's

Hi Brian,
Sounds like a fun time. :(
Can't comment on any except: - EMC re-test for some changes of PCB layout.
That is definitely a possibility but the change has to significantly change
some EMC parameter - clock speed, edges, extra high-speed surface tracks,
outside interface circuits, etc.
Gary,
I share your pain.
Another possibility is to offer to pay the company for the testing. That keeps
the liability with them, gets you your data, and all for the price you would
pay to do it yourself.
Good luck,
Marko

Can you change the WLAN to operate in 802.11a mode which uses the 5GHz

The Access Points will most likely be able to support 11a but older

ance significantly so you should be able to pass

heat carrying capability due to the decreased air density is off-set, at
least somewhat, by the loss of pressure needed to move the air (recall the

on your product.
You may also want to go to a better air filter if you have the space and/or
