The difference is the hub provides the same transmission chance for all
the packets but in wireless, high priority packets will block low
priority packets transmission. You can argue there is still chances a
low priority packet is sent first before a high priority one. But this
is not the point of wireless QoS. It rarely happens and should be avoid
at best effort in the implementation.
