Abstract: A communication apparatus detects a wireless device and calculates a relative position of the detected wireless device with respect to a reference wireless device to be a reference in identifying a position based on a movement amount of the communication apparatus from when the reference wireless device is detected by the communication apparatus. The communication apparatus associates the calculated relative position, identification information about the detected wireless device, and identification information about the reference wireless device.

Abstract: A reader apparatus detects a communication object by radiating radio waves and receiving a response, determines a change in a state based on at least one of a position and an inclination of the reader apparatus, and controls power consumed in the reader apparatus by setting a length of a first period, in which a reduction of power consumed in the detection is not performed, and a length of a second period, in which a reduction of the power is performed, based on the change in the state.
