Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when mounted on PCB as complete wireless module
Assembled modules with antennas and shielding become 'machines for reception, conversion and transmission of voice/data' under heading 8517
If primarily a processor with minimal RF capability
Processors without dedicated transceiver functions fall under 'processors and controllers' rather than specific RF transceivers
If for semiconductor media storage with RF
Devices combining significant storage function with RF may classify under solid-state storage media instead
