[@maruthkamath9304]

Highly recommended. Best explanation of 11ax . This covers a lot more than just OFDMA.

Great session indeed

[@techevangelist8373]

Hi.. Whe he says 1024 gives you 10bits per symbol.. Does that mean from an OFDMA standpoint, 10 bits per an ofdma tone/subcarrier?

[@keithsmyth6085]

Excellent video.

[@michal8kowalik]

Quality work.

[@ivandrofly]

Thank you so much... very clear explanation!

[@SovereignKnight74]

Great explanation. Apparently one person prefers outdated 802.11g.

Very nice video with a well structured explanation of OFDMA. Thanks! I still have a question: In the DL OFDMA frame exchange, the RUs are allocated using the MU-RTS frame (21:50), whereas in UL it is done via the Basic TFs (26:04). Why is the same feature (namely the transmission of the RU allocation info) solved using different frames? Am I missing something? cheers Ben

[@priceton_braswell]

this is amazing

[@oleksiimertymoshenko6100]

Nice done!

[@Layarion]

5:48 "uplink MU MIMO" um...other sources conflict with that info. Could you confirm this?

[@naWIN540]

It is included in wifi6-R2

[@mikethompson7406]

uhhhh.... what?? hahah I got the gist of it, multiple clients can now transmit at once. I think that's the important concept to understand here.

too few books on 802.11* updated.
