Hi zailon0,
Ok, thanks for the links, I will check them out. Just the last question, about this:
In your example, with the fourth number (4), this would mean that 4 spatial streams are available for MU-MIMO clients. So this could be 4 clients all with a single stream. The fifth number (3) represents how many clients could belong to the MU-MIMO Group.
Are you sure 4 clients simultaneously all with a single stream? Because the fifth number is 3 and then the AP will support up to 3 MU-MIMO clients simultaneously, but not 4.
Regards,
Julián
