The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then 
sets up a key hierarchy and management system, using the pair-wise key to dynamically 
generate unique data encryption keys to encrypt every data packet that is wirelessly 
communicated between the AP and the wireless clients.
