I assume by WiFi what is really meant is devices that have at least one WiFi (layer 1/layer 2) interface. While there are queues in the MAC sublayer, there is really no queue management functionality ... yet ... AFAIK. I know IEEE P802.11bd in conjunction w/ IEEE 1609 is working on implementing a few rudimentary queue mgmt functions.
That said, seems any AQM in such devices would more than likely be in layer 3 and above.

WiFi is a different challenge as you know. In this case it varies depending on the radio chipset vendor and is on my list of things to work on...

Awesome to hear that you are turning this on both upstream and downstream. Do you know if the wifi stacks in your home routers also have AQM?

The talk links to a just-published paper at https://urldefense.com/v3/__https://arxiv.org/abs/2107.13968__;!!CQl3mcHX2A!XLFMYPw-gnJgHzz_1nF-N7dNeIeT4QD-5wQny8vdAfYE6bzHtVQD3-lqiQI9YwCePfNyng$ (click PDF link in upper right of page) that will likely be of interest to these two lists.
