we have a question about how MU-MIMO works.
In our aps infraestructure (3915 and 3912 models) we only have 20MHz channels to avoid overlaping channels.
The aps are 2x2:2MU-MIMO. ¿our question is?
With a 20MHz using one antenna the aps can una 2 spatial streams to send trafic to 2 MU-MIMO clients? Or this only works when we have 40MHz Channel with 2 antennas working?
Sorry for the english
