Radio communication system, radio communication method, and data transmitter

摘要

Disclosed is a radio communication system capable of reducing the cost for introducing a system utilizing RFID technology into a radio network environment. A radio communication system pertaining to the present invention includes a first radio equipment that transmits first data using a first radio wave; a data transmitter that outputs a second radio wave generated by modulating the first radio wave depending on second data which is an object for transmission; and a second radio equipment that receives the first and second radio waves and includes a separation and demodulation circuit that separates and demodulates the first data transmitted from the first radio equipment and the second data transmitted from the data transmitter included in the received radio waves. The data transmitter includes an amplifier for generating the second radio wave by amplifying the first radio wave.
