    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： Described herein are systems, methods, and apparatuses for determining an optimal path in a mesh network. A pre-emptive message, such as a request to send (RTS) message, carrying, for example, an address of a target mobile device, may be sent from an access point to a computing device in a mesh network. The computing device may relay the RTS to the target mobile device. A clear to send (CTS) message and transmission parameters indicating channel conditions may be transmitted from the target mobile device to the access point via the computing device. The access point may determine an optimal path based on the transmission parameters and send data via the optimal path.

    摘要： 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.
