  • Publication number: 20190123812
    Abstract: Described herein are systems, devices, and methods that improve network communication on a high-latency network by using a low-latency network to manage return-link bandwidth. Embodiments of the systems described herein include a user terminal that is communicatively coupled to a high-latency network and a low-latency network. The user terminal is configured to communicate with a gateway routing device over the low-latency network. The user terminal requests return-link bandwidth and the gateway routing device provides a transmission schedule to the user terminal over the low-latency network. The user terminal can be configured to transmit a message over the high-latency network using the scheduled return-link bandwidth.

  • Patent number: 8737420
    Abstract: There is provided a powerline network that includes a number of stations including a central coordinator for coordinating transmissions of each of the stations. Each of the stations is configurable to generate one or more tone maps for communicating with each of the other stations in the powerline network. Each tone map includes a set of tones to be used on a communication link between two of the stations. Each tone map further includes a unique set of modulation methods for each tone. Each of the stations is further configurable to generate a default tone map for communicating with each of the other stations, where the default tone map is valid for all portions of a powerline cycle. Each of the stations is further configurable to monitor its bandwidth needs and to request additional bandwidth from the central coordinator.

  • Patent number: 8644341
    Abstract: A MAC layer protocol that converts packets into a data stream is presented. The protocol layer accepts packets (like Ethernet packets) and converts them into blocks. The packets may be segmented into multiple hocks and multiple packets or packet fragments may be contained in a block. The blocks contain information for reassembling the data. All blocks may be exactly the same size and format, with the same coding. This allows blocks to be precisely recovered even when some of the bits on the stream have errors on them. The blocks may be interleaved and coded. Each block may be decoded independently of other blocks. The blocks may be numbered, so an ARQ mechanism may request that any missing blocks be resent without asking for a whole packet to be resent. The data stream may be passed to a physical layer like an OFDM or WOFDM stream of data.

  • Patent number: 8553706
    Abstract: There is provided a powerline network that includes a number of stations including a central coordinator for coordinating transmissions of each of the stations. The central coordinator is configurable to transmit a beacon at an interval based on a phase of a powerline cycle. The interval of the beacon can be substantially equal to two periods of the powerline cycle. The interval of the beacon includes a reserved region including a persistent allocation region and a non-persistent allocation region. The beacon also includes a broadcast message including a persistent schedule and a non-persistent schedule. The persistent schedule is valid for a current beacon period and a number of subsequent beacon periods as indicated by the beacon, while the non-persistent schedule is valid for a single beacon period. The persistent allocation region and the non-persistent allocation region are determined based on the persistent schedule and the non-persistent schedule, respectively.

  • Patent number: 8509315
    Abstract: Synchronization of data streams is enabled. Synchronized data streams may include compressed data streams. Conventional data compression components may be utilized to generate the compressed data streams. As an example, compressed digitized video and associated metadata may be synchronized in this way. Synchronization may be enabled based on causing data compression components to generate detectable data units. For example, patterns of data units having well characterized entropies may be passed through data compression components to generate detectable patterns of compressed data units.

  • Patent number: 8089901
    Abstract: A method and corresponding system for operating in a network in which stations communicate over a shared medium are presented. The shared medium has at least one varying channel characteristic that varies approximately periodically. The method includes providing repeated beacon transmissions from a coordinator station for coordinating transmissions among a plurality of the stations, wherein at least some beacon transmissions are synchronized to the varying channel characteristic; and transmitting from a first station to at least one receiving station during a time slot determined based on at least one of the beacon transmissions received by the first station from the coordinator station.

  • Patent number: 7830907
    Abstract: Provided is a frame structure for filtered OFDM signaling, wherein once every frame a central controller passes redundant broadcast data for a short time (e.g. 16 symbol times) over all frequencies in use. This broadcast, called a beacon, may carry control information, frame structure information, and other data. The rest of the frame is divided into other assignments, including broadband redundantly coded channels for broadcast, ALOHA contention access, or point-to-point transmissions, and including traffic channels that may use only some of the assigned frequencies intended primarily for point-to-point access. This allows a mix of TDMA and FDMA point-to-point and broadband access. This system may be controlled by a central coordinator, which issues reservations. This system allows devices on a frequency-selective channel to communicate with scheduled operations.
