    Abstract: A system includes an analog front end (AFE) unit to be coupled to a power line network, and a controller coupled to the AFE unit. More specifically, the AFE unit is to receive a packet signal from the power line network wherein, based on a first gain parameter, the AFE unit is to amplify the received packet signal. The controller is configured to calculate a root-mean-square (RMS) power of the amplified packet signal. Further, the AFE unit is to calculate a second gain parameter based on the calculated RMS power of the amplified packet signal and the first gain parameter, wherein the second gain parameter is to be used to amplify the received packet signal instead of the first gain parameter.

    Abstract translation: 系统包括要耦合到电力线网络的模拟前端（AFE）单元和耦合到AFE单元的控制器。 更具体地说，AFE单元将从电力线网络接收分组信号，其中基于第一增益参数，AFE单元将放大接收的分组信号。 控制器被配置为计算放大的分组信号的均方根（RMS）功率。 此外，AFE单元是基于所计算的放大的分组信号的RMS功率和第一增益参数来计算第二增益参数，其中第二增益参数将用于放大接收的分组信号而不是第一增益参数 。

    Abstract: A method includes determining by a primary node a network formation process to establish a network with a secondary node according to a network condition of the primary node and the secondary node, the secondary node previously paired to the primary node in a previously established network connection between the primary node and the secondary node, performing by the primary node a scanning phase as part of the network formation process with the secondary node according to network configuration information stored by the primary node and the secondary node and obtained by the primary node and the secondary node in the previously established network connection; and skipping by the primary node a pairing phase of the network formation process with the secondary node responsive to the secondary node being previously paired to the primary node in the previously established network connection.

    Abstract: A system such as an electric meter includes a single-ended analog-to-digital converter which is susceptible to crosstalk. Methods and apparatus are disclosed to calibrate and cancel crosstalk effects. The system determines whether voltage-induced cross-talk is in-phase or out-of-phase with respect to voltage. The system determines a first calibration factor based on minimum and maximum measured current values and voltage. If the cross-talk is in-phase, the system sets a second calibration factor to 0. If the cross-talk is out-of-phase, the system computes the second calibration factor based on a measured current when a power factor angle is set to 90 degrees. Calibration factors may be stored in the multi-channel system. In use, the system measures current and voltage and computes the actual current, voltage and power based on the measured current and voltage by employing a crosstalk cancellation technique using the calibration factors.

    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.

    IPC: H04W52/02

    Abstract: A device includes a wireless transceiver coupled to a microcontroller. The microcontroller is configured to receive a first command from the wireless transceiver indicating an uplink allocation for the device, and in response to the first command, cause the wireless transceiver to turn ON at the beginning of the device's uplink allocation, send data to the wireless transceiver for wireless transmission, and cause the wireless transceiver to enter a low power mode after the data has been transmitted by the wireless transceiver. The microcontroller is also configured to receive a second command from the wireless transceiver to transition to a low power mode, and in response to the second command, send data to the wireless transceiver for wireless transmission during the uplink allocation for the device, and receive data from the wireless transceiver during uplink allocations for at least one other device.
