I think I misunderstood your question or observation, when you said earlier:

Your reference to 'transience', and to mobile being more practical, led me to think
mobile wireless, while clearly you were thinking fixed wireless.

Yes, with fixed wireless the operator has a similar level of visibilty and control,
and provided they don't overbook the capacity there should be no congestion.
Unfortunately the capacity of a wireless tower is likely to become filled more
quickly, so the refusal to set up new services once the available bandwidth is all
reserved could be interpreted as a form of congestion. The operator would call this
'admission control'.
