| 20090290531 | LARGE PACKET CONCATENATION IN SATELLITE COMMUNICATION SYSTEM - Upstream information arriving through a gateway from a user terminal in a satellite link subject to propagation delay is efficiently scheduled through a modified Demand Assigned Multiple Access (DAMA) algorithm such that arriving data packets arriving at the software queue at the user terminal are concatenated to form a large frame for transmission to improve efficiency. A piggyback request replacing a conventional DAMA contention request for the succeeding packet is issued to request bandwidth allocation for the succeeding concatenated packet. In a specific embodiment, all packets up to the physical request limit arriving at the user terminal since a prior piggyback request or contention request are concatenated so that all currently known packets (up to that limit) are accounted for by the next piggyback request. | 11-26-2009 |
| 20090290532 | MAP-TRIGGERED DUMP OF PACKETS IN SATELLITE COMMUNICATION SYSTEM - Upstream information arriving through a user terminal in a satellite link is efficiently scheduled through a modified Demand Assigned Multiple Access (DAMA) algorithm such that data packets arriving at the user terminal are concatenated to form a larger frame for transmission and the concatenated packet is held in a first queue disposed ahead of a second queue, where the data in the second queue cannot be modified (typically a hardware queue), sufficient to allow the second queue to be emptied. In a specific embodiment, all packets arriving at the user terminal since a prior piggyback request are concatenated so that all currently known packets (up to a preselected limit) are accounted for by each succeeding piggyback request. Since it is desirable to concatenate all packets that arrive at the user terminal since the last piggyback request, the piggyback request according to the invention covers all currently known packets (up to the preselected limit) in the user terminal. The held-back packets are released or dumped to the second queue by a trigger operative according to a map, the map being a grant allocation schedule. This mechanism handles instances where the second queue is not able to handle all known packets. | 11-26-2009 |

| 20100046421 | Multibeam Antenna System - Embodiments of the invention relate to beamforming antennas such as can be used in space division multiplexing systems. Space division multiplexing can be used to increase data capacity in wireless networks by enabling different base stations to transmit signals within the same frequency band. Each antenna beam can potentially be used to establish a communication link within an area of wireless coverage, and other communication links established on other antenna beams then represent interference to that user. In order to reduce interference, narrow beamwidths are desirable. These are typically achieved by increasing the aperture of the antenna in the azimuth plane, and in arrangements that require finely divided angular sectors, a greater number of antennas will be required to give three hundred and sixty degree coverage. As a result, there is potentially a large increase in the total surface area of antennas which is undesirable, as it leads to increased wind loading of an antenna tower. Embodiments of the invention provide an arrangement in which data are transmitted from a first transmitter to a first receiver using a first antenna beam, and data are transmitted from a second transmitter to a second receiver using a second antenna beam. The first antenna beam is formed by splitting the signal from the first transmitter into two parts with a first phase relationship between the parts, each part being connected to an antenna. A second antenna beam is formed by splitting the signal from the second transmitter into two parts with a second phase relationship between the parts, each part being connected to one of the two antennas.

The signal power allocated to each carrier is determined relative to a gain realizable by satellite terminals within the respective beam region and assigned to receive the respective carrier, and the realizable gain of the terminals is based on locations within the beam. The signal power level allocated to each carrier is different from the power allocated to the other carriers. | 06-30-2016 |
| 20160191148 | SYSTEMS AND METHODS FOR INCREASING THE TRANSMISSION SPEED OF A SATELLITE VSAT - Systems and methods are provided for increasing or decreasing the transmission speed of a VSAT used in a satellite network. A VSAT may include an ASIC and an FPGA in a transmission block of the VSAT. The ASIC includes an ASIC transmit modulator configured to modulate an input information signal, and circuitry for bypassing at least a portion of the ASIC transmit modulator. The FPGA includes circuitry for receiving a signal bypassing at least a portion of the ASIC transmit modulator, and an FPGA transmit modulator configured to modulate the bypassed signal. In implementations, the system uses the ASIC to burst format an input information signal with a payload burst segment; bypasses a transmit modulator of the ASIC after burst formatting the input information signal with the ASIC; and uses an FPGA to insert additional burst segments into the ASIC burst-formatted signal. | 06-30-2016 |
| 20160192303 | Apparatus and Method for Synchronizing Communication Between Systems with Different Clock Rates - An apparatus and method for synchronizing communication between systems having different clock rates, is described. The apparatus includes a communication unit, a synchronization unit, and an interface unit. The communication unit receives upstream information and generates a first sample stream representative of the upstream information based on a first clock rate. The synchronization unit converts the first sample stream to a second sample stream based on a second clock rate and in accordance with a predetermined burst plan. The interface unit receives the second sample stream at the second clock rate and outputs it based on the predetermined burst plan. | 06-30-2016 |
| 20160192311 | Apparatus and Method for Testing Synchronized Transmission Between Systems Operating at Different Clock Rates - An apparatus and method are disclosed for testing synchronization of transmission between systems operating at different clock rates. The apparatus includes a transmitting unit configured to operate at a first clock rate, and a receiving unit configured to operate at a second clock rate that is different from the first clock rate. A compensation circuit receives a second clock rate from a frequency generating system, and synchronizes the data transmitted by the transmitting unit with the second clock rate. The synchronized data is then transmitted to the receiving unit. | 06-30-2016 |

| 20220140891 | DYNAMIC SWITCHING OF SATELLITE INROUTE DATA PATH BETWEEN A TIME-DIVISION MULTIPLE ACCESS METHOD AND A TIME DIVISION MULTIPLEX METHOD - Some implementations of the disclosure relate to dynamic switching of a satellite inroute data path between a Time Division Multiple Access (TDMA) method and a Time Division Multiplexing (TDM) method. In one implementation, a method comprises: communicating, using a satellite terminal, over an inroute TDMA channel; determining, at the satellite terminal, based at least on an aggregate ingress traffic rate to the satellite terminal, to switch communications from the inroute TDMA channel to an inroute TDM channel; and after determining to switch communications, sending, from the satellite terminal to a Gateway Earth Station, a request to be allocated an inroute TDM channel. | 05-05-2022 |
