Abstract
A wireless communication system includes a plurality of wireless devices that communicate with each other. Each of the wireless devices includes a transmission unit configured to transmit a carrier of a fixed strength with polarization waves thereof rotated to a different one of the wireless devices using two antennae spatially orthogonal to each other, a reception unit configured to receive a carrier transmitted from the transmission unit of the different wireless device, and a timing detection unit configured to detect a timing at which the polarization waves of the carrier received by the reception unit within a period of rotation indicates a maximum strength. The transmission unit performs transmission or reception of a specific information signal using the carrier based on the timing detected by the timing detection unit.
