only when running Ethernet back-hauls to APs is not feasible
For businesses I agree with that, but why for at home? I’d prefer a mesh network (wired or wireless) over APs any day for at home. APs may provide better speed since each one creates its own signal but that’s a little unnecessary for most households, separate networks to manage etc.
I’m surprised powerline isn’t better these days, 80Mbs is pretty good though.
