satellite communication system with capability to geo mobile data transmission with high speed

摘要

A communication system for dynamically allocating resources to transmit both high bandwidth data and low bandwidth voice signals (20) employs a relay device (10), such as a beam forming satellite to cover several distinct geographical regions. A transmitting device (18) in a first beam (14) transmits a signal (20) to the relay device (10), which in turn retransmits the signal (20) to one or more receiving devices (16). The transmitting device (18) transmits first and second signals (20) using first and second time slots (24) and/or first and second carrier frequencies (26) to the relay device (10). The relay device (10) receives the signals (20) and subsequently retransmits the signals (20) using two time slots (24) and/or two carrier frequencies (26). The signals (20) are then recovered at one or more receiving devices (16) by demodulating one or both of the carrier frequencies (26) and/or monitoring two or more time slots (24) of the signal (20) (Fig. 3).
