In a wireless communication apparatus, data transmitted from at least one wireless transmitter is received by direct wireless communication, and its wireless reception condition is detected. Relation reference information setting two or more relations between the wireless reception condition on a reception of transmitted data and location information of the transmitter is stored. Relative distance information of a relative distance between the transmitter and the apparatus is measured. Relation information indicating a relation between the wireless reception conditions and the relative distance information is generated. A relation between the location information and the relative distance information is determined by comparing the relation reference information and the relation information. A current location of the apparatus is determined on the basis of the relation between the location information and the relative distance information and a current wireless reception condition.
