Abstract :
This paper describes a flexible way of evaluating the power line (PL) channel frequency response, H(f), and input impedance, in the frequency range of 0-30 MHz, by means of a two port network (TPN) methodology. As an example, the method is applied to investigate the power line channel variability under various practical load conditions in a typical modern Australian two bedroom apartment. In order to view the extremities of the channel variability, the channel links have been divided into short and long links. The results show that using short links have the benefits of reduced signal attenuation along with less susceptibility to the variations in the channel conditions.
