[Make-wifi-fast] Thoughts on tackling airtime fairness

[Luca Muscariello]

LTE-U and LTE-LAA are basically the same thing.
They require a licensed anchor.
MuLTEFire does not.

All needs to have a listen before talk and some level of fairness.

All these are gonna give a lot better quality and capacity than 802.11.
Enough to push 802.11 improvement in the standard?
