Have a Spitz GLX3000. Went into the Band Making Area to lock on to n71 and n41. I read that I should be able to connect to 2 5G-SA bands at once. I have both of them check, but I only can connect to n71. If I try and connect to n41 by itself, I can connect just fine. Cannot get connected to both bands at the same time. I read somewhere I can get on 2 5G-SA at same time
I did the AT+QCAINFO and it only shows me info for N71.
It's possible that the modem in the X3000 does not support connecting to n71 and n41 at the same time. You can check this website that may be of help determining which bands the X3000 can connect to simultaneously. Not all modems are capable of connecting all NR bands at the same time.
Whats the bandwidth per band? RM520 can only use up to 120mhz bandwidth and NR bands usually are 60mhz, 100mhz, or more thats why your modem can't used both of it at the same time.
