Can an access point facilitate a MAC address change of all its clients?

Hi all,

I am currently working on a project, and I am very new to networking. I was told that an enterprise access point can change all the MAC addresses of its clients. Is this true? And if so, how? Nothing turned up when I googled the question, and I'm not having much luck sifting through the 802.11 standards.

Any help would be appreciated. Thanks.
