A1
Abstract:
[PROBLEMS] To solve the problems of radio communication that communication is blocked off by a person or an obstacle, the communication speed is slow, and the distance where communication is enabled is too short. [MEANS FOR SOLVING PROBLEMS] There is provided a radio communication system including an oscillation unit for generating a plurality of carrier signals of different frequencies, an amplitude modulation unit for modulating the input signals according to the carrier signals and generating a plurality of modulated signals, a signal synthesis unit for synthesizing the modulated signals, a signal amplification unit for amplifying the synthesized modulated signal for output, and an excitation unit for exciting a conductor in a building or a campus according to the synthesized modulated signal which has been amplified and forming a radio communication space.
