Abstract :Power line communication insert ignore into journalissuearticles values(PLC); make use of existing power line infrastructure to transmit data over power lines with simultaneous transmission of electrical energy, a power line modem serves the purpose by modulating data through some suitable modulation scheme and then coupling it with power line. Power lines modem make use of existing power line for high frequency, low voltage data communication faces some serious problems like signal distortion, multipath fading, reflection and return loss and noise to communication signal. We designed a power line modem for 220V 50 Hz power line, which employ ASK modulation. Digital data of 9Kbps was modulated through carrier of 1 MHz and sent through power line and subsequently transmitted through VLC.
