Problems solved by technology

While such first generation satellite systems can provide full capacity at multiple gigabits per second (Gbps) per satellite, the design of such systems inherently limits the number of consumers that can be adequately served
Additionally, the fact that capacity is spread across multiple coverage areas further limits the bandwidth per subscriber
[0021] The demand for such broadband services continues to grow despite the multiple capacity constraints of existing designs

Abstract

A method is presented for transmitting data in a satellite system having multiple spot beams comprising (1) sending a broadband signal in a forward direction from a gateway terminal to a communications satellite for relay to at least one subscriber terminal, (2) receiving the broadband signal at the communications satellite, wherein the communications satellite comprises a bent pipe repeater having a plurality of satellite-based transmission amplifiers, (3) using one of the plurality of satellite-based transmission amplifiers to amplify the broadband signal and no other broadband signal from the gateway terminal, to produce an amplified broadband signal, (4) sending the amplified broadband signal as one of a plurality of service spot beams to the at least one subscriber terminal, and (5) receiving and retrieving data from the amplified broadband signal at the at least one subscriber terminal.
