This is very common on 2.4 GHz (and will happen by itself in a
controller-based setup). Anything that reduces the cell size is good
(assuming you have enough APs for all the resulting cells); if you go to big
stadiums etc., you will also see lots of directional antennas to reduce the
cell size further.

Note that the AP also can ask _clients_ to reduce their power level
accordingly.
