Abstract

A wireless communication device according to one embodiment includes a receiver, processing circuitry and a transmitter. The receiver receives a first signal obtained by a first sensor. The processing circuitry compares first sensing information included in the first signal with second sensing information obtained by a second sensor so as to determine whether or not the first sensing information and the second sensing information are obtained from a same target object. In addition, the transmitter transmits a wireless connection signal, when it is determined that the first sensing information and the second sensing information are obtained from the same target object. The wireless connection signal is a signal to connect one of an own device and an other communication device which has transmitted the first signal to a wireless network formed by the other of the own device and the other communication device.
