Abstract
The wireless communication system sets at least one of the multiple wireless frequencies as a reception frequency from the wireless tag, and controls the temperature of a superconducting filter in response to the selected reception frequency, thereby the pass band or the rejection band of the superconducting filter is controlled.
Claims13
A method of controlling communication frequencies of a wireless communication system including a wireless tag, a superconducting filter that passes or blocks at least one of the signals of multiple wireless frequencies used for communication with the wireless tag, and a controller that controls the temperature of the superconducting filter, the method comprising:
- on the controller,
- selecting at least one of the multiple wireless frequencies as a reception frequency from the wireless tag;
- and
- controlling the temperature of the superconducting filter in response to the selected frequency, whereby the pass band or rejection band of the superconducting filter is controlled.
A controller of the wireless communication system including a wireless tag;
- and a superconducting filter that passes or blocks at least one of the signals of multiple wireless frequencies used for communication with the wireless tag, the controller comprising:
- reception frequency setting unit that sets at least one of the multiple wireless frequencies as a reception frequency from the wireless tag, and
- temperature controlling unit that controls the temperature of the superconducting filter in response to the reception frequency selected by the reception frequency setting unit, whereby the pass band or rejection band of the superconducting filter is controlled.
A wireless communication system performing communication using a wireless tag and at least one of multiple wireless frequencies, the wireless communication system comprising:
- a superconducting filter that passes or blocks at least one of the signals of the multiple wireless frequencies;
- and
- a controller comprising reception frequency setting unit that sets at least one of the multiple wireless frequencies as a reception frequency from the wireless tag, and temperature controlling unit that controls the temperature of the superconducting filter in response to the reception frequency selected by the reception frequency setting unit, whereby the pass band or rejection band of the superconducting filter is controlled.
