How check if MIMO is working?

Hi team!

We have a Quectel RM500Q-AE connected into a network that is offering MIMO 2x2 in LTE band4.

We would like to know

  • If MIMO is 2x2 is supported, is not clear from the documenationwhat bands is that supporting
  • How we can know that MIMO 2X2 is active / Working , Any AT commands to check it?

Thank you!
