Hi, in the past I used the RM500Q-GL and can connect to a LTE network using band 28 (700MHz).
Now I received the -AE variant which I want to use because of the extended 5G NSA band support.
This new model didn’t find the above mentioned LTE network by using the same environment as before.
By using the qmicli network scan the network is no longer displayed.

Dear Steffen,
yes, RM500Q-AE could support more ENDC bands, especially nr FDD NSA combinations.
if used in US, you’d better choose RM500Q-AE. About your issue, could you help to send ATI/AT+CGATT?/AT+COPS?/AT+QENG=“SERVINGCELL”/AT+QNWPREFCFG=“mode_pref”/AT+QMBNCFG=“list”/AT+QMBNCFG=“autosel” and get the response information? Thanks.
Hi Peter, here are the output of the AT-commands:

By using qmicli I can see some more:

I use UBUNTU 20.10 and have connected only 2 antennas on the Modem (ANT0 and ANT3) which should support my network which works on band 28 (700MHz).
Dear Steffen,
The at log you sent doesn’t include ATI/AT+CSQ/AT+QNWPREFCFG=“mode_pref”/AT+QMBNCFG=“list”/AT+QMBNCFG=“autosel”, please do it and send the responses to me.
you also could fix LTE mode to test it again by using AT+QNWPREFCFG=“mode_pref”,LTE
By the way, where did you do the test and what is your company name?
Hi Peter,
I’m working for NOKIA in Germany and do the tests with our own on-air test network (PLMN 262 73). We use band 28 (700MHz) for LTE in this case.
The command output is:
+++
at+csq
NO CARRIER
at+qnwprefcfg=“mode_pref”
+QNWPREFCFG: “mode_pref”,LTE:NR5G
OK
at+qmbncfg=“list” - no result, is hanging
at+qmbncfg=“autosel” - no result, is hanging

I didn’t find the qmbn-commands in the AT-Command manual for RM500Q.
Hello Steffen,
Did you try lock LTE mode? and what is your RM500Q firmware version, you may use ATI to get.
please tell your email address, we might discuss via mail.
Hi Peter,
The RM500Q-AE Firmware version is: RM500QAEAAR11A01M4G
Please contact me by mail: steffen.schulz@nokia.com
OK, i have sent you mail, we might talk on there.thanks.
To finish this discussion - the problem was the changed assignment on the antenna connectors of the AE versions compared to the GL version. Low Band support is now for the AE model on ANT1+ANT2 and not ANT0 and ANT3.
Yes, thanks for your information.
