My understanding of RF theory sugggests that messing with the power
levels isnt really going to help much. It will just change the point at
which  one WAP becomes preferable to another.

What is important is to keep adjacent WAPS wide apart in channel spacing.

Multipath degrades signal quality but it does not change channel
frequencies!
