Anders, From personal experience, I believe SAR is the currently the primary reason for this restriction. Unless the device is an access point this will be your primary concern. What I've found works well is to do a new application for equipment authorization (new FCC ID) for the combined device, and re-submit the RF reports for each individual transmitter to avoid repeating a lot of testing. Note that you will likely have to upload the reports to the FCC again (they won't go pull them from their website/database - you have to supply them again).
I think the other option is to file permissive changes for the modules you want to place in the end product. This gets messy fast (particularly if you use the same modules across a few products, or if your company doesn't 'own' the original FCC ID's), so I'd recommend a single new FCC ID.

In our coming product we have two modules which is co-located, how do we solve this problem? Our thoughts right now is to use the modules FCC grants and do a FCC Self Declaration for the transmitting part for our units ( i.e. no own FCC id for our product). For my understanding: Why do the modules FCC grants have this restrictions? Can the manufacturer update the FCC grants without this restrictions and that are needed for that? Have we any more solutions to solve this? Any inputs is very much appreciated Thanks Regards Anders - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
