摘要

There is provided a wireless tag position estimation system which includes a wireless tag communication device and a wireless tag position estimation device and estimates a position of an article on which a wireless tag is fitted regardless of an arrangement, an appearance, and a package of the article. The wireless tag communication device includes a unit which irradiates a radiowave from a predetermined position and direction to the wireless tag, and a unit which receives a response signal from the wireless tag with respect to radiowave irradiation. The wireless tag position estimation device includes a unit which estimates information about a specific position and direction which irradiates a radiowave when a response from the wireless tag can be received on the basis of the information received by the wireless tag communication device, and a unit which estimates the position of the wireless tag on the basis of estimated information.
