Mu-Mimo and 802.11g. Will I get multiple parallel streams? (Cisco Aironet 1815i Access Point)

Hi Folks!

I've got a question related to Mu-Mimo Wave 2 and 802.11g. As we know "Mu" supports multiple streams in parallel. Does it mean that if I have one device which is 802.11n and another 802.11g, then they can receive and send in parallel? Or user devices must be 802.11n and higher? Thank you very much.

It means that if a wireless clients has two (or more) antennas then it can receive two (or more) data stream which will arrive at the same time.
If the wireless client only has a single antenna (which a lot of wireless clients nowadays have) then MU really isn't applicable.

Thank you Leo. Also, I just got to know that Mu-Mimo doesnt supprt 802.11g. So if there are two user devices - one is 802.11g and another is 802.11g, there will not be 2 simultaneously streams. Even 802.11n is not supported by MU-MIMO, unfortunately.
