OFDMA: The Key Technology of 802.11ax 

High quality, good voice, easy to understand ! appreciate for good presentation.

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

The best explanation of 802.11ax I found on the Internet!

Excellent planning of slides and video Series taking us through 802.11ax journey. Thank you very much.

Great presentation summarizing OFDMA in 11ax !!

Fantastic overview of AX. And yeah, Dragon's Lair? Great illustration. :)

Really good explanation and great use of visual aids. Really good work.

Great session indeed

Quality work.

Excellent video.

Thank you so much... very clear explanation!

Nice done!

this is amazing

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

Great explanation. Apparently one person prefers outdated 802.11g.

can you make a video on 802.11be please , a comparison table with WiFi6E?

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

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.
