摘要： Systems and methods configured to form and manage different types of beams toward target ground terminals to “optimally” communicate with the terminals. In one set of embodiments, the UAV generates a set of beams to cover cells on the ground, the beams are divided into groups, and the UAV communications system deterministically and sequentially turns a subset of the beams on/off to reduce cross-beam interference and increase system throughput. In another embodiment, in order to increase throughput, the UAV communications system determines the highest data rate on the downlink and uplink that are decodable at the receiver given the received signal to interference plus noise ratio (SINR) while maintaining a low packet error rate. Systems and methods are described to determine the UAV antenna pattern toward different terminals needed for SINR calculation and data rate determination.

摘要： Systems and methods are provided to achieve dynamic bandwidth allocation among terminal groups (TGs) with proportional fairness in terms of both throughput and spectrum usage across a network. Quality of service (QoS) metrics for such TGs can be satisfied in terms of maximum throughput and spectrum utilization, while also satisfying QoS metrics such as latency, throughput, and prioritized traffic services for individual terminals within the TGs. A centralized bandwidth manager can be utilized to manage such dynamic bandwidth allocation across multiple Code Rate Organizers (CROs), including environments in which the multiple CROs manage communications across multiple IPGWs for multiple terminal groups. Because, in such environments, a given conventional CRO cannot effectively manage allocations across the entire network, the centralized bandwidth management functionality can be introduced to assess the flows for multiple TGs across multiple CROs and to make bandwidth allocations accordingly.

摘要： A broadband communication system with improved latency is disclosed. The system employs acceleration of secure web-based communications over a satellite communication network. In accordance with aspects of the invention, secure protocol acceleration is employed such that required protocol signals transmitted from a computer employing a web browser may be intercepted by a remote terminal. To insure that the browser will continue transmitting data, the remote terminal generates required acknowledgment and security signals to continue the secure communication, which may then transmitted back to the computer. Meanwhile, the received protocol signals may be converted by the remote terminal for transmission through the satellite communications system in a format appropriate for that communication medium. Aspects of the invention further include a hub or similar device for communicating with the satellite communications system.

摘要： A method for determining attenuation settings across carriers in a return link bandwidth of a user terminal comprises determining a first attenuation setting for a user terminal at a first transmission frequency, where the first attenuation setting is based on a first signal quality metric value of a first message sent from the user terminal at the first transmission frequency. The method also comprises determining a second attenuation setting for the user terminal at a second transmission frequency, where the second attenuation setting is based on a second signal quality metric value of a second message sent from the user terminal at the second transmission frequency. The method also comprises determining the attenuation settings across the carriers in the return link bandwidth of the user terminal based on the first attenuation setting and the second attenuation setting.

摘要： A method and system are provided for allocating satellite resources in a satellite communication system. A network interface is provided for making requests for satellite resources. A request processor determines whether the requests can be fulfilled based on a plurality of system constraints. The constraints can include, for example, the number of antennas on board the satellite, the number of active demodulators available on board the satellite, the configuration of a switch matrix which connects antennas to demodulators, and interference between signals transmitted to and from neighboring geographic cells. The network interface is preferably implemented in a web browser connected to a network which includes the Internet.

摘要： Methods and systems to efficiently share multiple satellites and associated transponders or links among a network of uplinking earth stations are disclosed. An embodiment of this invention uses a terrestrial communications link, such as the Internet, to control access to the transponder or satellite links. Communications over this link may employ a TCP/IP protocol to connect the requesting uplinking earth stations with a centralized controller. This control system creates more efficient use of satellite resources and reduces the overall amount of time needed for transmitting data through the satellite. By reducing the overall amount of time needed for transmitting data, the control system may reduce the cost of using the satellite transponder capacity.
