Hopefully someone can shed some light here.
Our modem consists of off-the-shelf single-board computer with Sierra Wireless 3G module in cPCI-E slot.
3G module has all relevant approvals. Single board computer has CE and FCC approvals. Now, we want to deploy the solution in USA, Europe and Australia and I am trying to figure out some certification issues.
For USA we need:
FCC (as far as I understand we only need 15 Part B)
PTCRB (this can largely be leveraged from module certification)
AT&T and T-Mobile approvals (those are carriers we plan to use)
Main question – what will happen if we decide to change the 3G module for a different type (module will have all the approvals, of course). We may have to go to LTE modules later on. Do we have to go through all of the approvals again???
For Europe we need CE approvals. R&TTE part should be leveraged off existing module approval. Again, do we have to re-approve if we change module?
For Australia, we need A-tick. I was told by local test house that we can exchange the modules, as long as new one is compliant.
As far as I can see, our solution is not much different from a laptop with 3G modem. Do laptop manufacturers have to go through re-approval for each new module they use?
Any advise, links, etc… are appreciated. I read lots of documents already, but not clear on the subject and different test houses give different advises.
