In a wireless information distribution apparatus, a transmission unit transmits radio waves for distributing information. An adjustment unit acquires first data indicating a degree in which a person is present around the wireless information distribution apparatus. Moreover, the adjustment unit acquires second data serving as an index of a possibility that another apparatus that distributes information by radio waves is present around the wireless information distribution apparatus. The adjustment unit adjusts, based on the first data and the second data, the intensity of the radio waves to be transmitted by the transmission unit.
