Does Forti AP U431F Support 4x4 MU-MIMO

HI~ According to https://www.fortinet.com/content/dam/fortinet/assets/data-sheets/fortiap-u-series.pdf  FortiAP U431F FAP-U431F Indoor Wireless Universal AP - Tri radio (2x 802.11 a/b/g/n/ac/ax, 4x4 MIMO and 1x 802.11 a/b/g/n/ac Wave 2, 2x2 MU-MIMO)

 

Does that means FAP-U431F only support 2x2 MU-MIMO at Radio3 ? Radio 1 and Radio 2 only support SU-MIMO ? Thank you~

As in the wiki description, an additional signaling is used for uplink MU-MIMO, the clients need to support it. Those devices with "ax" support should be the ones. And off course multiple ax clients are needed to see the difference.

Hi Toshi Esumi,

thanks for the information.

According to wiki,  802.11ax support MU-MIMO and OFDMA natively.

  

But  my  client device only got 802.11ac adapter.

Some of those adapter support MU-MIMO (EW-7822ULC), and some doesn't (Intel AC8260 ).

 

That's why i want to figure out FAP-U431F's radio1 and radio2 supports 802.11ac 4x4 MU-MIMO or not.

 

 

Maybe i can make some performace test to figure it out. 

Or, raise  the budget , replace them to Intel AX200 wifi adapter.

Hi James,  

thanks for the advice.

Seems like the temporary workaround is POE+ injector.
