How are you going to make the latency determination?

I guess that anywhere there are a lot of APs you can connect to, they are managed
entity with some sort of global controller for that location.  So then the controller can make
the decision.  That general ability for controller to manage stations already
exists in wifi, but someone will have to make a clever controller...

If it is wired/fiber backhaul, then probably everyone shares same uplink so selecting strongest
AP is best option.

If wifi backhaul, you need a lot more cleverness to manage stations properly.

Thanks,
Ben
