摘要： A communication device includes an antenna, a driving unit, a first acquisition unit, an input unit, and a second acquisition unit. The driving unit moves a position of the antenna. The first acquisition unit acquires tag data of each radio tag based on a radio wave of each radio tag received by the antenna at a plurality of positions of the antenna. The input unit inputs the tag data of each radio tag at the plurality of positions of the antenna into a learned model. The second acquisition unit acquires, from the learned model, data indicating whether each radio tag is included in a first range or a second range based on the input of the tag data of each radio tag into the learned model by the input unit.

摘要： A quadrature modulator and the transmission unit output a modulated wave obtained by performing quadrature modulation on a carrier wave using a first I signal and a first Q signal and wirelessly transmit the modulated wave. A reception unit and the quadrature detector detect a received signal corresponding to a wireless signal transmitted from the wireless tag using the carrier wave and to output a second I signal and a second Q signal. A filter and the amplification unit amplify a frequency component higher than a cutoff frequency in the second I signal and the second Q signal. A detector and the decoding unit decode data based on a detection signal obtained by detecting the amplified second I signal and the amplified second Q signal. A generation unit generates the first I signal and the first Q signal such that the modulated wave is a signal obtained by shifting a frequency of the carrier wave by a frequency shift amount more than the cutoff frequency and to input the first I signal and the first Q signal to the quadrature modulator.
