A 
wireless digital personal 
communications system (or PCS) having a plurality of radio 
cell base stations, fixed terminals, and portable 
handset terminals, each having a predetermined radio 
cell coverage area. The 
wireless PCS has a full 
digital network interface. The personal 
communications system facilitates the 
interconnection and switching of PCS call traffic through the 
digital network interface and the public switched 
telephone network, or any switched network. The personal 
communications system has voice / data / image (or any combination thereof) and incoming and outgoing calling capability. The PCS is fully operational and compatible with any and all modulation approaches selected for 
wireless communications. The intercell protocol hand-off being provided through 
distributed logic which is implemented in 
software that is resident in the intelligent portable 
handset terminals, in the intelligent fixed terminals, in the intelligent base stations, and in the public switched 
telephone network (or any switched network). Alternative embodiments of the present invention include a wireless digital personal communications 
system having 
authentication means for authenticating a remote device; a wireless digital personal communications 
system having a combination of 
authentication means for authenticating a remote device and security means for securing 
signal and message content between an intelligent 
base station and a remote device, the security means including a predetermined 
encryption and decryption technique; a wireless digital personal communications 
system having dynamic zone grouping of portable 
handset terminals or fixed terminals; and a wireless digital personal communications system having 
call forwarding for unanswered calls.
