For more on the behavior of communications signals on ac power lines, see the technical paper "Attenuation of Communication Signals on Residential and Commercial Intrabuilding Power-Distribution Circuits" by Morgan H. L. Chan and Robert W. Donaldson. Data derived from five buildings, over a frequency range of 20 to 240 kHz, as well as cross-phase measurements, are included. The paper was published in the IEEE Transactions on Electromagnetic Compatibility, Vol. EMC-28, no. 4, November 1986, starting on p. 220.
