ABSTRACT:
A wireless communication system (100) having portable communication devices (102, 104, and106) capable of establishing direct terminal (102)-to-terminal (104) communication (108and110) and indirect terminal (102)-to-terminal (104) communication (112, 118and114, 116) through another terminal (106) without having a fixed base station. A portable communication device (106) used as a terminal is capable functioning as a router for communication (112, 118and114, 116) between other portable devices (102and104) in the system. While functioning as a router, the portable device (106) is capable establishing and maintaining a separate direct communication (302and304) with another portable communication device (306). A wireless communication system(600) utilizing predetermined cell- and location-specific communication parameters (808) and non-repeating propagation patterns (1200) for portables communication devices in the system for establishing communications.
