Abstract
A load power monitoring apparatus and method use a power line communication apparatus and method. The power line communication apparatus is capable of performing power line communication through a simple circuit structure by loading a data signal on a current signal supplied over the power line. The power line communication apparatus includes a transmission unit configured to generate a data signal using the current signal, which is supplied through the power line, as a carrier wave, and to transmit the data signal through the power line, and a reception unit configured to receive the data signal, which is generated by the transmission unit, through the power line.
