Private 5G Network Connection

[LudwigBAH]

Hi Devs,
I wanted to know if there have 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.

We have tested the Sierra modems using our own private network. We have not tried the Quectel RM502Q-AE modems ourselves, though they are unlocked. So, as long as the SIM is configured properly it seems likely to work, but we have not verified ourselves.

Hi @Chad-Sweet and Dev Team,

I'm also configuring RB5 to connect to our 5G private network. After run rb5-modem-configure to configure quectel the APN.

We get this error:

How can I change MCC, and MNC in the configuration? Thank you.

@kitkatSG @LudwigBAH Copying my response from another thread:

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
