Abstract :
The paper deals with narrow band power line channel for low voltage access network in China. Major channel characteristics such as access impedances, interferences, and attenuations for frequency between 30-500 kHz are evaluated based on measurements results in a typical urban underground network. Coupling mode has a significant impact on the performance of narrow band power line communication. Comparison of impedance, noise and attenuation between single phase and three phase coupling is given. Link Quality Index (LQI) derived from noise and attenuation is introduced to compare different channels. Examples of available SNR for the considered LV network using LQI approach with CENELEC A band signal such as PRIME are given.
