not without using other technologies - as each AP runs the authentication
so your client needs to reauthenticate when associating with each AP

you can start off by using the 'speed' command to select the supported
connection rates - but a decent antennae may negate the 'security' of
such a setup. personally i feel that WPA2 is strong enough that it doesnt 
matter if the signal can be received from further away. you could also
turn down the power of the antennae (antenna gain) - but, once again, that
will affect how your own users will receive the wireless.  place
a decent zinc/neodynium mesh or somesuch in your wall cavities - there
are some papers out there describing such blocking methods.

apart from how it appears in CDP, inventory lists and its bootloader? 
no functional difference as far as i'm aware.
