In this paper, the characteristics of the household AC power line network is analyzed for the low bit rate powerline communication (PLC) in the frequency range from 10㎑ to 450㎑ The PLC channel transfer characteristics including its characteristic impedance are derived based on the network topology which is constructed with the household power lines loaded with the various types of electric apparatus. Both the distributed circuit analysis and the lumped circuit model based analysis are applied for the characterization of the PLC channel and the results are compared by the computer simulations. The analysis illustrates very well the adverse effects caused by the loading of electric apparatus and as well those casued by the reflection of wavers in the household AC Power line communication network.
