    Abstract: A first microwave backhaul transceiver may comprise a plurality of antenna elements. The transceiver may determine atmospheric conditions between it and one or more potential link partners, and adjust a radiation pattern of the plurality of antenna elements based on the determined atmospheric conditions. A first radiation pattern of the plurality of antenna elements may correspond to a first microwave backhaul link between the first microwave transceiver and a second microwave backhaul transceiver. A second radiation pattern of the plurality of antenna elements may correspond to a second microwave backhaul link between the first microwave transceiver and a third microwave backhaul transceiver. The transceiver may adjust the radiation pattern based on characteristics of data to be transmitted, and based on a routing table it maintains.

    Abstract: Aspects of a method and system for high-speed, low-power optical communications are provided. In one embodiment, a system for optical communications comprises a digital-to-analog converter (DAC), a driver, and a transmit optical subsystem. The DAC is operable to receive a digital code of a plurality of digital codes and output an analog current signal having an analog current level of a plurality of analog current levels. The driver is operable to condition the analog current signal output from the digital-to-analog converter. The transmit optical subsystem is operable to generate an optical power signal from the conditioned analog current signal. A mapping between the plurality of digital codes and the plurality of analog current levels is dynamically controlled according to one or more characteristics of the optical power signal. The one or more characteristics comprise or a symbol amplitude sensitivity and/or a nonlinearity that may be temperature dependent.

    Abstract: A receiver includes a plurality of input paths for receiving and processing a plurality of input RF signals. The input paths isolate one or more portions of corresponding ones of the received input RF signals, and combine the isolated portions of the corresponding ones of the received input RF signals onto one or more output signals. A bandwidth of the isolated portions of the corresponding ones of the received input RF signals and a bandwidth of the output signals are variable. The isolated portions of the corresponding ones of the received plurality of input RF signals are extracted and utilized to generate the output signals. The portions of the corresponding ones of the received plurality of input RF signals may be mapped into one or more channel slots in the time domain. The channel slots may be assigned in the frequency domain to one or more frequency bins.

    Abstract: A remote control unit of an unmanned vehicle comprises a first communications subsystem, a processor, and a graphics processor. The first communications subsystem may be operable to receive sensor data via a first communication link between the remote control unit and the unmanned vehicle. The processor may be operable to determine a position and orientation of the unmanned vehicle based on the sensor data. The first communication subsystem may be operable to receive, via a second communication link between the remote control unit and the unmanned vehicle, a live first-person view from a camera of the unmanned vehicle. The graphics processor may be operable to generate a virtual first-person view from apriori data based on the sensor data. The processor may be operable to determine whether to present said live first-person view or said virtual first-person view based on signal quality of said second communication link.

    Abstract: A WiFi access point (AP) includes a receive radio frequency (RF) front end and a baseband processor that controls operation of the receive RF front end. The RF front end captures signals over a wide spectrum that includes a plurality of WiFi frequency bands (2.4 GHz and 5 GHz) and channelizes one or more WiFi channels from the captured signals. The baseband processor combines a plurality of blocks of WiFi channels to create one or more aggregated WiFi channels. The receive RF front end may be integrated on a first integrated circuit and the baseband processor may be integrated on a second integrated circuit. The first and second integrated circuits may be integrated on a single package. The RF front end and the baseband processor may be integrated on a single integrated circuit. The WiFi access point comprises a routing module that is communicatively coupled to the baseband processor.

    Abstract: In a first configuration, circuitry of a fiber node may be configured to modulate an optical carrier by an analog upstream electrical signal received via the electrical network. In a second configuration, the circuitry may be configured to digitize the analog upstream electrical signal to generate a digitized upstream signal, and modulate the optical carrier with the digitized upstream signal. An optical receiver of the fiber node may be configured to convert a downstream optical signal to a downstream electrical signal. In the first configuration, the downstream electrical signal may be a first analog signal and the circuitry may be configured to output the first analog signal into the electrical network. In a third configuration, the downstream electrical signal is a digitized waveform and the circuitry is configured to convert the digitized waveform to a second analog signal and output the second analog signal into the electrical network.

    Abstract: Methods and systems are provided for adaptive management of local networks (e.g., in-premises networks, which may access or be connected to cable or satellite networks). A network device (e.g., a gateway device) may be configured to function as a network manager in a local network, to manage internal connections and/or communications within the local network. The managing may comprise assessing effects of the internal connections and/or communications on external connections and/or communications with one or more devices and/or networks external the local network; and setting and/or adjusting based on the assessed effects, one or more communication parameters associated with each one of the internal connections and/or communications. The effects of the internal connections and/or communications may result from utilizing one or more physical mediums that are shared with and/or are commonly used by the external connections and/or communications with one or more devices and/or networks external the local network.
