Sure it depends on device location and clients density. We've been using
multiple radio devices for a while, and talking in general, I could
clearly point a couple of tips.
-Avoid 802.11g for clients, use 802.11b instead, if not it could result
a very noisy environment.
-Look for positions where the coverage can be done by patch/sector
antennas instead of omnis.
