I've been enjoying this discussion and wonder whether the work going on in the make-wifi-fast (https://lists.bufferbloat.net/pipermail/make-wifi-fast/) is relevant.

I only have a 30,000 foot understanding of this work, but it seems the use of AQL (Airtime Queue Limit) maps better onto the vagaries of 4G/5G radio transmissions than BQL. Specifically, having a measurement of the actual time it takes to transmit a packet might give additional information about the current link speed, with the potential for adjusting the codel target, etc.

Separately, I also wonder whether the Air Time Fairness algorithm might provide a benefit if the cellphone tower station manufacturers chose to get into the game.

Thanks.
