20100254386 | ACCESS NETWORK ARCHITECTURE HAVING DISSIMILAR ACCESS SUB-NETWORKS - A subscriber network architecture includes a packet processing node that communicates with a network backbone and with a plurality of access nodes. The access nodes communicate with a plurality of user devices. The packet processing node controls Quality of Service (QoS) levels for the subscriber devices, routes user data to devices via the access nodes and receives data from devices via the access nodes for forwarding across the network backbone. | 10-07-2010 |
20110243563 | Binary Modulation Node - Digital information can be carried on the fiber leg of an access network using binary modulation. Binary modulated data received at an O/E node can then be modulated onto an analog waveform using quadrature amplitude modulation or some other technique for modulating an analog waveform and transmitted over, for example, the coaxial leg of the network. The O/E node may also receive an analog signal, over the coaxial leg, modulated to carry upstream data from subscriber devices. The O/E node may demodulate the upstream signal to recover the upstream data and forward that upstream data over the fiber leg using a binary modulated optical signal. | 10-06-2011 |
20110271313 | Multi-Mode Modem - A modem system may include modems that have multiple upstream transmitters for transmitting signals upstream in a communication network. In some embodiments herein, one or more of those upstream transmitters may be retasked to transmit downstream signals for reception at devices within a modem's premises. The downstream signal may be modulated differently from its original modulation as received by the modem, and may be modulated in a manner that can be received by legacy components on the premises, such as analog televisions. | 11-03-2011 |
20110274148 | Managing Upstream Transmission in a Network - A bandwidth allocation and monitoring method may divide available bandwidth on a shared communication medium into a plurality of discrete tones that can be individually allocated to modems on an as-needed basis. The effective modulation rate that a particular modem can use for each discrete tone can be monitored over time using a schedule of pilot tones transmitted from the modems on different tones at different times. The schedule may define representative pilot tones, in which case effective modulation rates for neighboring tones may be inferred from a determined effective modulation rate of a pilot tone. | 11-10-2011 |
20120096492 | TRANSMISSION OF VIDEO SIGNALS - An apparatus, method, and system are described for transmitting a television program signal. A portion of a local frequency spectrum may be determined to be free, or relatively unused. A user selection of a television program or broadcast programming channel may be received from a program lineup in an electronic programming guide. The selected program may be selected from a gateway, translated, and transmitted over the portion of the frequency spectrum determined to be free. The translation may include converting a signal from the gateway into a National Television Systems Committee (NTSC) signal or a mobile TV signal. | 04-19-2012 |
20130051314 | DATA GATHERING FOR A NODE - Methods and systems are disclosed including a mobile device configured for initiating a communication session with a transceiver interface of a node that comprises a network interface. The node may be queried via the communication session for a status report associated with an error, and an instruction may be communicated to the node via the communication session instructing the node to perform an operation. Communication may be established with the wireless access point via the wireless network after communication of the instruction. The transceiver interface may be configured to communicate via a second network to address issues in the wide area network. | 02-28-2013 |
20130061276 | Transmitting Signals Using Directional Diversity Over a Network - Methods and systems are disclosed for using a common frequency spectrum for simultaneous upstream and downstream communications in a network by implementing directional diversity techniques. Non-reciprocal coupling devices, such as circulators, may be configured in the network to provide unidirectional transmission of each signal to prevent interference. In some embodiments, feed-forward interference cancellation is utilized to increase signal isolation of upstream and downstream signals. | 03-07-2013 |
20130091267 | Smart Gateway - A smart gateway is disclosed for use in a local network for detecting a network configuration, for detecting devices connected to the network, and for providing configurable signal conditioning to correct problems in the network. The smart gateway includes an analysis circuit for testing the electrical properties of different network branches, and includes configurable signal conditioning circuitry for optimizing the performance of the network. | 04-11-2013 |

The downstream signal may be modulated differently from its original modulation as received by the modem, and may be modulated in a manner that can be received by legacy components on the premises, such as analog televisions. | 12-19-2013 |
