Data bit error rates for power line carrier data transmission, in commercial and industrial applications, such as in office buildings and manufacturing plants is improved by connecting the power line transceiver modem to the power line via a booster amplifier and filter circuit which raises the carrier data signal level of the order of 20 dB, thereby overcoming spikes and other noise which can adversely affect the error rate. The power for the carrier data transmission system is obtained from the power lines over which the data is transmitted through filters which isolate the power supply from the power line thereby reducing the introduction of power supply noise into the power line and further improving the data bit error rate.
