Abstract
A radio communication apparatus includes antennas, transceiver units respectively connected to the antennas, and a radio control unit that controls the transceiver units, simultaneously inputs same transmission data to the transceiver units, and instructs, every switching cycle of frequency hopping, the transceiver units to start check processing for an idle state of frequency channels. The transceiver units respectively include hopping control units that switch the frequency channels every fixed time in synchronization with a communication partner and control such that each of the transceiver units uses a different frequency at the same hour. When determining that a frequency channel is in an idle state before a predetermined time elapses from the start of the check processing for an idle state, the transceiver units transmit the transmission data to the communication partner using the frequency channel.
