RADIO COMMUNICATION TERMINAL DEVICE, CONNECTOR DEVICE, CHARGER, AND COMMUNICATION METHOD AND REPEATING METHOD

摘要: PROBLEM TO BE SOLVED: To achieve power-line carrier communication by a portable telephone using charging base. SOLUTION: In data transmission, base-band processor 10-3 of body 101 generates and modulates digital transmit data, D/A circuit 105 converts the from to analog, coupling 106 outputs analog contact 108 for electric base 102 applies them power line 110. reception, inputs receive sent 110 through 102, an A/D 104 performs conversion, 103 demodulates data.
