Description

Embodiments of the present invention relate to a communication device and a program. There is a device that determines the range containing a wireless tag by receiving radio waves transmitted from the tag attached to an item using an antenna. Such a device detects the phase of the wireless tag by moving the antenna. The device determines the range containing the wireless tag based on the detected phase pattern. For example, if a wireless tag is located within a predetermined range, the device can determine that the wireless tag is within the predetermined range based on the detected phase pattern. Here, when a person attempts to place an item with a wireless tag attached, or an enclosure containing such an item, within a predetermined range, the item or enclosure may extend beyond the predetermined range. When the item or enclosure extends beyond the predetermined range, the wireless tag attached to the item may also extend beyond the predetermined range. Depending on the position of the wireless tag, the phase pattern detected for this wireless tag may resemble the phase pattern in a different range than the phase pattern within the predetermined range. In such cases, the device determines that the wireless tag is within the other range. However, since this wireless tag should ideally be placed within the predetermined range, it is undesirable for it to be determined to be within the other range.

(Embodiment) The communication system according to the embodiment will be described below with reference to the drawings. Note that the scale of the parts in the drawings used in the description of the embodiment below may have been changed as appropriate. Also, for illustrative purposes, some components may be omitted from the drawings used in the description of the embodiment below. (Example configuration) Figure 1 is a block diagram showing an example of the configuration of communication system 1. The communication system 1 includes a communication device 10, a terminal 400, and one or more wireless tags 600 attached to one or more articles 500. Figure 1 shows one wireless tag 600 attached to one article 500, but the communication system 1 may include multiple wireless tags 600 attached to multiple articles 500. Although the communication system 1 includes the communication device 10 and the terminal 400, it does not have to include one or more articles 500. The communication system 1 is an example of an information processing system. The communication device 10 is a device that communicates wirelessly with the wireless tag 600. The communication device 10 can be applied to inspections in warehouses, but it may also be used in stores; the applications of the communication device 10 are not limited to these. The communication device 10 includes a reader 100, a drive unit 200, an antenna 300, and a measuring device 800. The reader device 100 controls the drive unit 200 and antenna 300 to read information from the wireless tag 600. The reader device 100 also controls the drive unit 200 and antenna 3
