802.11ax white papers

Tim mentioned 11ax in passing in his CES 2017 overview and some might be curious about what's new in that version of WiFi

Here's a couple of whitepapers that serve as an intro...

This one item along is going to help out huge - but it's a big step for the air interface...

Bringing in OFDMA is bringing in a scheduled MAC - and this is Wimax like technology - QCOM suggests this is LTE, but Wimax/802.16 was ahead of 3GPP2 here...

We need a scheduled MAC for Uplink MU-MIMO (11ac MU is downlink only) so that way members of the MU group can transmit in a coherent manner to the AP.

Anyways - while 802.16e/m kinda lost in the 4G wars, a lot of good stuff was done there - we were always trying to push that interface.

But 802.11 was kind of verboten for us in the 802.16 camp with regards to contributions - 11 always had the advantage of much higher channel bandwidths, and there were things that could be done here, but without scheduling...

Brings back old memories about 802.20 and our contributions there - NB-SDMA (e.g. iBurst), along with our own internal work on 802.16 to bring benefits there for capacity...

Nice to see some mention of 11ah in Qualcomm's presentation...

(FWIW - their marketing team needs to be aware that some of us are color-enhanced, e.g. color-blind, so some of the slides basically lose the message) - the slide below is basically useless... can't see the important parts in a native colorspace...
