ABSTRACT:
A wireless handset is provided with enhanced features and capabilities. The wireless handset may be embodied as a full-featured handset that is capable of operating either within a wireless network (such as a cellular or PCS network) or in a direct handset-to-handset communication mode that is independent of the wireless network. Alternatively, the wireless handset may be embodied as a special purpose handset, that is capable of simply operating in a direct handset-to-handset communication mode. The wireless handset may additionally include features for supporting and enhancing direct communication between handsets. Such features may include a find feature that permits a user to determine which objects, including other wireless handset users, are located within a predetermined operating range of the wireless handset. A memorize feature may also be provided to permit handsets and other objects exchange information by wireless transmission.
