Abstract
According to one embodiment, a tag reader comprises a communication interface connectable to an external device, a communication control circuit configured to output a tag interrogation signal at different output levels from an antenna and receive a tag response signal via the antenna, and a processor. The processor is configured to notify the external device, via the communication interface, of an output level of the tag interrogation signal corresponding to a received tag response signal from a wireless tag, a tag identification of the wireless tag included in the received tag response signal, and an indication of a signal strength of the received tag response signal.
Claims20
A tag reader, comprising:
- a communication interface connectable to an external device;
- a communication control circuit configured to output a tag interrogation signal at different output levels from an antenna and receive a tag response signal via the antenna;
- a processor configured to notify the external device via the communication interface of:
- an output level of the tag interrogation signal corresponding to a received tag response signal from a wireless tag,
- a tag identification of the wireless tag included in the received tag response signal, and
- an indication of a signal strength of the received tag response signal.
A wireless tag reading system, comprising:
- a tag reading including:
- an antenna;
- a first communication interface;
- a communication control circuit configured to output a tag interrogation signal at different output levels from the antenna and receive a tag response signal via the antenna;
- a first processor configured to transmit via the first communication interface:
- an output level of the tag interrogation signal corresponding to a received tag response signal from a wireless tag,
- a tag identification of the wireless tag included in the received tag response signal, and
- an indication of a signal strength of the received tag response signal;
- and
- an external device including:
- a second processor configured to receive the output level, the tag identification, and the indication of the signal strength from the tag reader via the first communication interface and detect a movement of the wireless tag based on the received output level, tag identification, and indication of the signal strength.
A tag reader connected to a host device, the tag reader comprising:
- a communication control circuit configured to output a tag interrogation signal at different output levels from an antenna and receive a tag response signal via the antenna;
- a first processor configured to notify a host device of:
- an output level of the tag interrogation signal corresponding to a received tag response signal from a wireless tag,
- a tag identification of the wireless tag included in the received tag response signal, and
- an indication of a signal strength of the received tag response signal.
