Problems solved by technology

While such first generation satellite systems may provide multi-gigabit per second (Gbps) per satellite overall capacity, the design of such systems inherently limits the number of customers that may be adequately served.
Moreover, the fact that the capacity is split across numerous coverage areas further limits the bandwidth to each subscriber.
While existing designs have a number of capacity limitations, the demand for such broadband services continues to grow.

Abstract

A satellite system for broadband communication with a plurality of remote locations is described. The satellite system comprises service spot beams from a satellite. Forward channels may be transported on carriers of the service spot beams. A plurality of forward sub-channels may be passed on the forward channels. A plurality of logical downstreams may correspond one-to-one with the plurality of forward sub-channels. The satellite system may further include a satellite modem with a channel bonding unit that combines a plurality of logical downstreams into a downstream group and processes the downstream group to provide information to customer premises equipment.
