Wireless communication device, wireless communication system and wireless communication method

Abstract

This wireless communication device is provided with antennas (151, 152), transceiver units (11, 12) connected to each of the antennas (151, 152), and a wireless control unit (101) which controls the transceiver units (11, 12), simultaneously inputs the same transmission data to the transceiver units (11, 12), and, for each switching period of frequency hopping, instructs transceiver units (11, 12) to start idle state confirmation processing for a frequency channel, wherein each of the transceiver units (11, 12) is provided with a hopping control unit (111, 112) which performs control such that the frequency channel is switched at fixed time intervals in synchronization with the communication partner and such that, at the same times, different frequencies are used in each of the transceiver units (11, 12). If, in the interval before a prescribed time has elapsed from the start of idle state confirmation processing, a frequency channel is determined to be in an idle state, then said frequency channel is used to transmit the aforementioned transmission data to the communication partner.
