<P>PROBLEM TO BE SOLVED: To provide an electronic apparatus with high reliability at a low cost by enhancing a conventional radio communication technology, applying the enhanced technology to data transmission in the same electronic apparatus, adopting radio transmission to a method of a high speed transmission of data wherein various problems and constraints exist and eliminating the defect and restriction of data transmission systems of prior arts. <P>SOLUTION: The electronic apparatus includes: a radio transmission section for modulating first category information and transmitting the modulated information as an electromagnetic wave signal; a radio reception section for receiving and demodulating the electromagnetic wave signal; a wired transmission section for superimposing second category information on a signal on a power line and transmitting the information; and a wired reception section for separating the signal superimposed on the signal on the power line. The radio transmission section and the wired transmission section transmit the first and second category information items at the same time. Further, power is supplied to the radio transmission section and the wireless reception section via the common power line. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
