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.

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.

If you are using a manufacturer supplied radio stack you may be able to leverage their certification but if you wrote your own stack you will need to do the authorization independently. There are a number of consultancies in the US who will handle the process for you (for a fee of course). A long time ago (2006) I was on a project that needed such certification and the vendor hired charged $50,000 and it took four months to complete. They did all the required paperwork and followed up on all of the questions the FCC had, they also flew out an engineer to an FCC certified test facility to get the verification tests done. (I live in the San Francisco bay area and the FCC testing facilities around here are typically reserved months, if not years, in advance it seems).
