The present invention provides a multiple band mobile radio (also referred to as a Wireless Communication Device (WCD)) (102) capable of communicating with both a satellite communication system (108, 114) and a terrestrial communication system (120, 122). The satellite communication system can be, for example, a Low Earth Orbit (LEO) satellite system. The terrestrial communication system can be a Personal Communication System (PCS), or a cellular system, including either an analog or a digitally based cellular syst.sim.m. The cellular analog system can be AMPS. The digitally based cellular system can be a CDMA or a TDMA based communication system. The WCD (102,300,400,500,600,700, 800,900, 1000, 1100) can concurrently receive signals from the terrestrial communication system and the satellite communication system.

La présente invention concerne un dispositif radio mobile multibande(appelé aussi dispositif de communication sans fil (WCD)) (102) capable de communiquer avec un système de communication par satellite (108, 114) et avec un système de communication terrestre (120, 122). Le système de communication par satellite peut être, par exemple, un système satellitaire à orbite basse (LEO). Le système de communication terrestre peut être un système de communications personnelles (PCS) ou un système cellulaire comprenant soit un système cellulaire analogique, soit un système cellulaire numérique. Le système cellulaire analogique peut être un système AMPS. Le système cellulaire numérique peut être un système AMCR ou un système de communication AMRT. Les dispositifs de communication sans fil (102,300,400,500,600,700, 800,900, 1000, 1100) peuvent recevoir aussi bien des signaux en provenance d'un système de communication terrestre que des signaux en provenance d'un système de communication par satellite.
