I know that the Digi XBee 3 Global and Low-Power LTE-M/NB-IoT module comes with FCC modular precertification. My question is, if I am only using the cell radio and disconnecting the BLE and GNSS antennas, does the module still hold this certification?
IF you are not using these functions, then as far as I am aware, it should. But that is really a question you should ask a certified FCC testing house.
