QUESTION

asked by
Is it possible to create a modem/SoC that can use both LTE-M, LTE-NbIOT, LTE-Cat (n) and LTE450 bands
We want to build an IoT controller that can use both spectra, the standard LTE bands and the 450LTE bands, particularly Band 31. I know that it would need different antennas for the two networks, the question is, if both could be mounted  and connected to the same device (PCB), obviously with only one being active at a time, without causing interference in the other? Would this mean actually 4 antennas, 2 for each band family?
Thanks

Hi,

Are you using a main and diversity antenna configuration for each band family? If so you will need 2 antennas for each band family.

Do you want the antennas to be SMD or FPC? SMD will require the antennas placed on the board whereas FPC will be stuck onto the internal side of the housing.
