Abstract: Various arrangements for a satellite-based forward link overlay are presented herein. In some embodiments, broadband data is modulated at a particular frequency, phase, and/or timing to create a broadband data signal. The frequency, phase, and/or timing are used to modulate a low-bandwidth data signal. The low-bandwidth data signal can then be combined with the broadband data signal and transmitted via satellite to a geographic region. A low-bandwidth receiver unit may determine the frequency, phase, and/or timing from the embedded broadband signal and use such information to demodulate and despread the low-bandwidth data signal.

Abstract: Various arrangements for increasing a transfer rate of a data transfer via satellite are presented. A satellite gateway may set an accelerated set of communication parameters that control communication between the satellite gateway and the satellite terminal via the satellite and between the satellite gateway and the content source to an accelerated transfer rate between the content source and the satellite terminal. A first set of data may be transferred from the content source to the satellite terminal using the set of communication parameters. After transferring the first set of data, the satellite gateway may adjust the initial set of communication parameters to an adjusted set of communication parameters. The adjusted transfer rate can be lower than the accelerated transfer rate.

Abstract: An apparatus and method for using a bandwidth (BW) allocation in a Time Division Multiple Access (TDMA) network. The method includes filling a buffer having a buffer length with a demand-inducing stream data until either the demand-inducing stream data is exhausted or the buffer length equals the BW allocation, determining a leftover BW as the BW allocation minus the buffer length after the filling, composing a leftover buffer when demand-deferring stream data is present, where the leftover buffer includes a transmission header (TH) and a transmission data (TD) includes a portion of a demand-deferring stream data, and transmitting the buffer and the leftover buffer in a time slot associated with the BW allocation. In the method, a length of the TH plus a length of the TD is less than or equal to the leftover BW.

Abstract: A method for balancing inroute traffic load that contains both guaranteed QoS and best effort traffic. Hierarchical grouping levels are defined with the lowest level corresponding to inroutes within the system. Certain levels have common symbol rates, modulation rates, or both. When a new terminal requires admission, it is assigned to entries in the different hierarchical levels so that the inroute traffic load across all levels are balanced. Terminals are admitted to inroutes based, in part, on their channel quality indicator. Inroute traffic load can periodically rebalance based on elapsed time or terminal redistribution.
