Abstract:
1. A wireless communication device for transmitting and receiving a signal by wireless communication using a millimeter wave frequency band, the wireless communication device comprising: one or more antennas having directivities in a plurality of different directions; an antenna controller adapted to select and form a directivity in a prescribed direction among the plurality of directivities for the one or more antennas; a direction and position estimator adapted to estimate direction and position information of a target wireless communication device to be communicated with, which is a target of the wireless communication, in accordance with a reception signal received by the one or more antennas having the selected and formed directivity; and a display adapted to display the estimated direction and position information of the target wireless communication device, wherein the one or more antennas receive a specific information signal including identification information of the target wireless communication device transmitted from the target wireless communication device, and wherein the direction and position estimator derives a received signal SN ratio of the specific information signal from the received specific information signal, and estimates position information out of the direction and position information of the target wireless communication device based on the received signal SN ratio.
