             BARRY, Administrative Patent Judge.                                                                     


                                               DECISION ON APPEAL                                                    
                    A patent examiner rejected claims 1-18.  The appellant appeals therefrom under                   
             35 U.S.C. § 134(a).  We reverse.                                                                        


                                                  BACKGROUND                                                         
                    The appellant’s invention is a satellite communication (“SATCOM”) system                         
             operating in a "mobile-to-mobile" mode in which mobile telephones communicate via a                     
             satellite.  In a typical SATCOM system operating in a mobile-to-mobile mode, mobile                     
             telephones transmit communication signals at a first carrier bandwidth (e.g., 50 kHz)                   
             and receive communication signals at a second carrier bandwidth (e.g., 200 kHz).
