Characteristics Analysis of Powerline Channel for Powerline Communication

전력선 통신을 위한 채널 특성 분석

The role of power line is not limited to providing electrical power. Power line fumed out to be an candidate to cope with the existing communication channels. It is need to be measured the properties of power line as communication channels, before successful communication system is possible. This paper presents the characteristics of power line noise and attenuation measurements in the frequency range of $0{\sim}10$ MHz, and then suggests applicable communication techniques in brief. Power line channel is configured in our laboratory and the length of it is 250 meters.
