nRF9151 technical questions

[Nick Zhong]

  1. What is the antenna output of the DECT NR+? Is it the same pin as CAT-M/NBIoT antenna output? (i.e. pin 35)

    2. In Section 8.3 of OPS document about DECT NR+, it mentioned: "Note: While running DECT NR+ firmware, the nRF9151 SiP does not support LTE modem....". So, is it possible to run DECT NR+ and Cat-M/NBIoT at the same time in a single firmware? If no, can we switch between DECT NR+ and Cat-M/NBIoT in a single firmware?

Hi,

Can you provide a link to the OPS you are referring to?

Hi,

DECT NR+ uses the same onboard antenna as CAT-M/NB-IoT.

2. In Section 8.3 of OPS document about DECT NR+, it mentioned: "Note: While running DECT NR+ firmware, the nRF9151 SiP does not support LTE modem....". So, is it possible to run DECT NR+ and Cat-M/NBIoT at the same time in a single firmware? If no, can we switch between DECT NR+ and Cat-M/NBIoT in a single firmware?

DECT NR+ is a physical layer firmware with a different radio technology than cellular firmware. Switching between wireless standards is not possible within the same firmware.
