[Hackrf-dev] Fwd: HackRF for preliminary FCC home test?

[Chuck McManis]

> What do you mean by a radio stack?

Many modules that implement various radio protocols run software on a
captive microprocessor. That software implements the protocol and drives
the radio electronics. For example TI offers firmware that runs on the
processor inside their CC3000 series chips that implement the Bluetooth
protocols. If a project uses their software in this chip, it can take
advantage of TI's efforts to get that software certified (see this:
http://processors.wiki.ti.com/index.php/CC3000_Product_Certification) which
saves time and effort.

For Part 15 certification (unintended emissions) you need to get a
certificate from a testing laboratory that is certified by the FCC. They
will put your product in a chamber that absorbs all RF with a wide band
detector and spectrum analyzer. The will detect all of the unintended
emissions and chart them in frequency and dBm. You take their report and a
certification that you aren't going to change the design, and submit that
to the FCC and they will give you a certification ID.

Note that the FCC won't accept your testing, they only accept a certified
lab's test results.
