A transmitter communicates with a receiver via a satellite station that transmits a signal by a multibeam system. The transmitter includes a scheduler and a transmission unit. The scheduler performs scheduling to determine a time and a wireless channel to transmit data addressed to the receiver based on an area where the receiver is present. The transmission unit transmits a signal of the data addressed to the receiver to the satellite station by the wireless channel determined by the scheduler and at the time determined by the scheduler. The signal transmitted from the transmission unit by an i-th (i is an integer of 1 or larger) wireless channel is transmitted from the satellite station to the receiver by an i-th beam. Frequencies of signals transmitted from the satellite station by respective beams are same.
