Is it possible to update the modem on a 5G Raspberry development kit to support band n48? Is this a firmware update or can the modem be replaced?
Dear @ka_oh,
The modem included in the current 5G Raspberry Pi Development Kit (Quectel RM502Q-AE) cannot be updated via firmware to support Band n48. This module has been deprecated and does not support n48.
However, the OEM has introduced a replacement module, the Quectel RM520N-GL, which does support Band n48. This modem will be part of our upcoming 5G Development Kit (B82), expected to be available around January 2026.
Please let us know if you need any further information.
