| Abstract: | There is a bright future for the AMR(automatic meter reading)system in which the information is transmitted by use of power distribution networks.The design of AMR system is related with the channel characteristics of power distribution networks.Based on the practical measurements,the three main characteristics including attenuation,noises and the input impedance are discussed respectively,then some key technological factors are given out that should be taken into account in designing the AMR system. |
