MU-MIMO report?

[patoberli]

Hi

Is there a way to see how many of my connected clients already support MU-MIMO?

It's enabled on the WLC (8.5.131.0) and my APs are mostly 2802i. 

I also have Prime Infrastructure 3.4, but so far haven't found a place to see the capability. 

Thanks

I don't know how to get a report over multiple clients

if you browse into the controller and select the home-button upper-right, then you can graphicallly drill-down into a client

and get this info:

so the info is there at the controller.......

I'm not sure, but I only see here if the client is MIMO capable, but not if it's MU-MIMO capable?!?

[pieterh]

the diagram I presented shows 3 blue boxes for the AP and 2 for the client
so this AP can process 3 spatial streams and the client 2

-> multiple streams to the same client, this is the MU- in MU-MIMO 

[patoberli]

Both must support this feature, otherwise it won't work.

I'm just curious to see how many of my client base is already capable of MU-MIMO.

[patoberli]

No, this is already possible for 802.11n clients. It is separate from MU-MIMO. It's actually possible to have clients with 1 Spatial Streams to be MU-MIMO capable. This is actually the main scenario for this new feature.

Hi Patoberli,

I came across this mu-mimo  link I wanted to share

I know, a wiki is not necessarily true, but if you look at other info on this site, the owner seems knowledgeable enough.

extract from page:

In MU-MIMO (Multi User MIMO), AP transmits stream to different users (Group) at the same time using isolated antenna pattern with beamforming. It is also called as “beamforming MIMO”.

Downlink (from AP to non-AP station) is defined in 11ac and UP link will be introduced in 11ax. (find MU Operation & Downlink chapter)

Thanks. 

To bad I can't see any real information on the WLC though, would be nice (also for Manager reasons) to have some information to show the reached gains and the spread of the capable clients.

And I really look forward for OFDMA in 802.11ax, err I mean Wi-Fi 6.
