摘要： In various embodiments, a power-line communication apparatus provides data over a power-line communication network by transmitting data symbols to endpoint circuits over a power line. The power-line communication apparatus includes a signal-processing circuit configured to combine a plurality of different data streams, each of the plurality of different data streams respectively formatted according to different communication schemes, to form a signal that represents a combination of the different data streams and corresponding communication schemes. Further, the power-line communication apparatus includes a pulse-modulation circuit configured to convert the signals, as combined, as a pulse-width modulated or a pulse-density modulated signal, the pulse-modulation circuit configured to switch at a frequency higher than frequencies of the different communication schemes. An output circuit can be configured to filter the switching frequency and to couple the data symbols to an injector transformer for presentation to the endpoint circuits.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for transmitting data. In one aspect, a method obtains a baseline data rate for transmissions from a node that are received over a channel of a power line communications system and a set of available modulation techniques for the node. The set of available modulation techniques can include at least two modulation techniques with which the node is configured to encode data that are transmitted over the channel. Using the set of available modulation techniques, a modulation technique that is capable of providing at least the baseline data rate with at least a threshold confidence for the node is selected. In turn, data is provided to the node specifying the selected modulation technique.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for authenticating a communications source. In one aspect, a method includes decrypting a symbol that was received over a particular communications channel. The symbol is decrypted using a decryption key that is assigned to a particular endpoint that is assigned the particular communications channel. A measure of error is computed for the decrypted symbol. In turn, a determination is made whether the measure of error exceeds a threshold error measure. If the measure of error does not exceed the threshold error measure the decrypted symbol is identified as a valid symbol transmitted by the particular endpoint, and logged as such. If the measure of error exceeds the threshold error measure, the decrypted symbol is identified as a symbol from a different endpoint.

摘要： In one or more embodiments, a plurality of PLC endpoints and a data processing circuit are configured to share information, in the form of data blocks over power lines in a power line communication (PLC) network. A first signal representing a transmitted one of the data blocks is received over a first one of the plurality of different communication channels. A second signal representing the transmitted one of the data blocks is received over a second one of the plurality of different communication channels. Information carried by said one of the data blocks is discerned, as a function of a signal versus noise measure associated with the first signal and the second signal, by combining energy from the first and second signals, and converting the combined energy for generating output data.

摘要： Aspects of the present disclosure are also directed towards a method that includes maintaining a transmission period which has a start time and an end time synchronized to metrological time. Further, this method, in response to the start time, begins transmission of a frame, which includes a plurality of symbols. This transmission occurs over power distribution lines that carry power using alternating current (AC). This method also includes synchronizing a transmission time for each symbol of the plurality of symbols according to a time-based parameter of the AC. In response to reaching an end of the frame, a synchronization symbol period is determined for a synchronization symbol, as a function of the transmission times, for the plurality of symbols and time from the end of the frame to the end time. The synchronization symbol is then transmitted on the power distribution lines.

摘要： Aspects of the present disclosure are directed toward power outage assessment using customer-site communication devices which are powered by utility power lines and which communicate with a remotely-situated computer server over a broadband network according to certain schedules. The server can receive from the devices, communications indicative of an operating status of each respective communication device as expected according to the schedules. In response to receiving and/or not receiving the respective communications from the devices and taking into account other parameters, the server can assess a possible power outage within one or more regions by comparing the received communications and threshold criteria associated with the schedules. Based on such criteria, the server can detect and report on conditions suggestive of a power outage in regions associated with the communication devices.

摘要： Power-line communication (PLC) systems collect information over power lines from end-point devices respectively associated with customer sites, for assessment by a central processing circuit operated on behalf of a power utility company. In the PLC system, each of a number of PLC data-collector circuits includes a plurality of data interface units and PLC end-point device data computation circuit. Typically, one data interface circuit is located proximate, and another is distal, the location of the computation circuit. Each data interface unit includes a transformer circuit for selectively receiving data from a subset of the end-point devices via the power lines, a transformer-coupling circuit for selectively sending data to the subset of the end-point devices via the power lines, and a high-throughput data driver circuit for outputting data in accordance with a data-transfer protocol which is common to the other high throughput driver circuits which operate in accordance with the data-transfer protocol.
