ABSTRACT:
An area estimation apparatus100includes: a reception level receiving unit110configured to receive, from a plurality of the radio signal capturing terminals40aand40bvia the network, a radio signal reception level transmitted from the radio signal transmitting terminal10, a radio signal transmitting terminal ID for uniquely identifying the radio signal transmitting terminal10, and a radio signal capturing terminal ID for uniquely identifying each of the plurality of radio signal capturing terminals40aand40b; with a presence area of the radio signal capturing terminals being known; a reception level storage unit123configured to store the radio signal reception level, the radio signal transmitting terminal ID and the radio signal capturing terminal ID, which are received from each of the radio signal capturing terminals40aand40b, in association with one another; and a presence area estimating unit140configured to refer to the reception level storage unit and to estimate the presence area of the radio signal transmitting terminal10, by using at least one presence area of at least one radio signal capturing terminal40aidentified by at least one radio signal capturing terminal ID associated with a predetermined range of at least one radio signal reception level.
