Is 54Mbit wireless like "hub" or "switch"?

Wireless access points have only one "channel" (two in dual band) 
available.  So, you could have only one or two devices communicating at 
a time.  Also, g, b and some n use the 2.7 GHz band. (a and some n on 5 
GHz), so even if you had one device using g and one n, they'd still be 
sharing the channel.  Not only that, but the presence of b will have a 
performance impact on the g devices.

With WiFi, the bandwidth is shared, just like with a hub.
