To all german speaking WLAN Pros: We are setting up a Slack-Channel to bring together the WiFi-Community in the DACH region and share ideas/experiences.
You can send me your mail via DM if you want to join. Feel free to RT or share with others that might be interested.

@GjermundRaaen @CWNP Yes, in the first example I disabled both A-MSDU and A-MPDU, and in the 2nd example I disabled A-MPDU on purpose on my AP to be able to show the differences

Could be helpful for folks preparing for @CWNP exams such as #cwna or #cwap or just regular #wifi nerds :)

@GjermundRaaen @CWNP The number of frames do not define if it's an A-MPDU since a single frame could be one too. the presence of a Block Ack indicates that it's an A-MPDU.
But other than that, I second your statement.

@WifiKohai @CWNP You're welcome!
I put my AP on channel 52 with 40MHz channel width, and then just took one sniffer and listened on channel 52@40MHz.
You could also do the tests with only a 20MHz channel

@ericsweber @CWNP Thank you Eric :)

[Renzo Notter @RenzoNotter]

@GjermundRaaen @CWNP My understanding is that it is only a mix of A-MSDU and MPDU in an A-MPDU if the transmitter decides to do so (lack of frames in buffer?). My example was during a filedownload, so the AP had lots of frames in its buffer

@EnyinniaE @CWNP You're very welcome!

[Renzo Notter @RenzoNotter]

@basdegruijter @CWNP Thanks man :)

[Renzo Notter @RenzoNotter]

@WazzFi @CWNP Cheers mate, I'm really glad that you enjoy them!

[Renzo Notter @RenzoNotter]

@GjermundRaaen @CWNP Thanks Gjermund!
Yeah, I wanted to keep it at a higher level, since I consider this only an additional puzzle piece that I personally missed from the books and articles I mentioned in the post.
Which part do you think is not correct?

[Renzo Notter @RenzoNotter]

@GjermundRaaen Cheers mate, happy birthday! :D

[Renzo Notter @RenzoNotter]

@GjermundRaaen Ah, maybe this: you can track authentication events in the windows eventlog (eventvwr.msc) under Applications and Services Logs => Microsoft => Windows => WLAN-AutoConfig => Operational

@get_max @KeithRParsons Had talked to @Mac_WiFi about this in Prague. By 2020, there will not be a ax Vocera phone. Is the plan to use dedicated VoWLAN phones, or regular smartphones with a softclient? Because by the end of this year, a lot of vendors will sell ax smartphones
