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: A power line communication system includes a first power line communication device. The first device is configured to communicate via conductors of an electrical power distribution system. The first device has a transmitter power control system which is configured to determine transmission power needed to communicate with a second device of a power line communication network. The first device also configured to apply the determined transmission power to communicate with the second device. The determined transmission power is insufficient to communicate with a third device of the power line communication network, and the transmitter power control system is configured to determine transmission power needed to communicate with a third device.
