Connecting to a private 5G network

chris_macdonald

Hello,
Have there been any successful connections of the RB5 to a private 5G network? For example, the iphone doesn’t work on private network unless it’s a CBRS band.

Hi @chris_macdonald ,
How is the status of your 5G private network connection?
I face similar issue when connect the RB5 to my 5G private network. After carefully inserting a sim card to the slot, the quectel-CM -s $APN does not allow me to choose PLMN. How do you solve this issue? Thank you.

@chris_macdonald @kitkatSG Here is an example of how to send an AT command to the Quectel modem:

echo -ne "AT+QNWPREFCFG=\"mode_pref\",LTE:NR5G\r" | busybox microcom -t 1000 /dev/ttyUSB2

The above gets ran as part of rb5-modem in order to set the network preference to allow both LTE and 5G.

Here is a link to the Quectel RM5* series modem AT command manual, you can probably find a relevant AT command to use there: https://www.quectel.com/wp-content/uploads/2021/05/Quectel_RG50xQRM5xxQ_Series_AT_Commands_Manual_V1.2.pdf
