Does EM9190 support SA 4x4 MIMO?
Hi @ssc ,
I found the information below in Product Technical Specification
FR1: not supported
FR2: 2x2 UL MIMO
2x2 DL MIMO are supported on all bands. The antenna ports for FR1 are Primary (TRx) and
Diversity (DRx) ports except for n41 whose 2x2 DL MIMO is supported by MIMO1/2.
4x4 DL MIMO can be supported on FR1 bands n1/2/3/71/251/381/401/41/481/66/77/78/79.
SRS fast hopping: Not supported.
2x2 DL MIMO are supported on all bands. The antenna ports are Primary (TRx) and Diversity (DRx) ports.
4x4 DL MIMO can be supported on bands B1/2/3/4/7/25/30/32/34/38/39/40/41/42/431/48/66
Please refer to the document for more 5G and LTE features in detail. Let me know if you have any concerns. Help us tick Solution under my response if it is helpful. That might is useful for someone have same question
Re the questions you need to be pretty precise when asking about specific supported features on 5G as they are complicated ad it is easy to say yes we support x if you look at it from a specific point of view.
Re the SA vs NSA question, yes the unit supports SA but like everyone else we are dependent on the Qualcomm signaling stack ion the SDX55 (which right now everyone, without exception, has to use).
Thanks for the summary Vianney! That helps.
Thanks @mlw. That helps to clarify that SA 4x4 MIMO is supported.
