Abstract: At least some aspects of the present disclosure provide for a method of data transmission, performed by a wireless device. In some examples, the method includes receiving a localization tone having a first value. The method further includes inserting the localization tone into a data packet at an application layer of a communication protocol stack, the localization tone preceding data of a payload of the data packet and having a last bit immediately preceding a first bit of the data of the payload. The method further includes generating a modified localization tone estimating an effect of processing on the localization tone, wherein the modified localization tone is generated and configured to have the first value after undergoing processing. The method further includes replacing the localization tone in the data packet with the modified localization tone. The method further includes transmitting the data packet.

Abstract: A power line communication (PLC) network includes a plurality of PLC devices. One such PLC device may include a transmitter power control system that determines a minimum level of transmission power for sufficiently communicating a plurality of data packets from the PLC device over the PLC network to a first destination PLC device on the PLC network by executing a training sequence over the PLC network via an electrical power distribution system. The transmitter power control system applies this minimum level of transmission power to transmit the data packets to the first destination PLC device.

Abstract: A band of interest is divided into band segments. A scan frame is sent by a transmitter at a transmitting PLC node across each band segment. A receiver at a receiving node scans the band segments, listening for the scan frame. Upon detecting a scan frame, the receiving node measures the signal quality of each OFDM subcarrier modulated with symbols from the scan frame. The subcarrier signal quality values are stored in a table. Upon completion of the scan process, the table contains a signal quality value for each subcarrier within the band of interest. The table is then analyzed to find an operating band consisting of subcarriers with a highest average signal quality or a band that results in greater than a pre-determined minimum signal quality. The invented methods and embodiments may operate periodically to readjust the operating band configuration in the presence of electromagnetic interference including time-variant interference.
