Abstract

An interrogator includes: an acquisition unit acquiring an identifier which is stored in a wireless tag and specifies a type of the wireless tag; and a communication unit executing wireless communication using a communication command at transmission power according to the acquired identifier.

Claims

1. An interrogator comprising:

an acquisition unit acquiring an identifier which is stored in a wireless tag and specifies a type of the wireless tag; and

a communication unit executing wireless communication using a communication command at transmission power according to the acquired identifier.

2. The interrogator according to claim 1, wherein the identifier includes a tag designer identifier and a model identifier.

3. The interrogator according to claim 1, wherein the identifier includes a tag designer identifier, a model identifier, and an antenna identifier.

4. The interrogator according to claim 1, wherein the communication command is a reading command and predetermined processing is performed only on the wireless tag responding by wireless communication using the reading command.

5. The interrogator according to claim 4, wherein an intensity level of a received data signal is detected when the wireless tag responds by the wireless communication using the reading command and the predetermined processing is performed only when the intensity level is equal to or greater than a minimum intensity level according to the identifier.

6. The interrogator according to claim 4, wherein the predetermined processing is a writing process for the wireless tag.

7. The interrogator according to claim 1, further comprising:

a storage medium,

wherein the storage medium stores the transmission power and the identifier in correspondence therewith.

8. A method of controlling an interrogator comprising:

acquiring an identifier which is stored in a wireless tag and specifies a type of the wireless tag; and

executing wireless communication using a communication command at transmission power according to the acquired identifier.

9. The method according to claim 8, wherein the identifier includes a tag designer identifier and a model identifier.

10. The method according to claim 8, wherein the identifier includes a tag designer identifier, a model identifier, and an antenna identifier.

11. The method according to claim 8, wherein the communication command is a reading command and predetermined processing is performed only on the wireless tag responding by wireless communication using the reading command.

12. The method according to claim 11, further comprising:

detecting an intensity level of a received data signal when the wireless tag responds by the wireless communication using the reading command; and

performing the predetermined processing only when the intensity level is equal to or greater than a minimum intensity level according to the identifier.

13. The method according to claim 11, wherein the predetermined processing is a writing process for the wireless tag.

14. The method according to claim 8, further comprising:

storing the transmission power and the identifier in correspondence therewith.

15. An interrogator comprising:

an acquisition unit configured to acquire an identifier which is stored in a wireless tag and specifies a type of the wireless tag; and

a communication unit configured to execute wireless communication using a communication command at transmission power according to the acquired identifier.

16. The interrogator according to claim 15, wherein the identifier includes a tag designer identifier and a model identifier.

17. The interrogator according to claim 15, wherein the identifier includes a tag designer identifier, a model identifier, and an antenna identifier.

18. The interrogator according to claim 15, wherein the communication command is a reading command and predetermined processing is performed only on the wireless tag responding by wireless communication using the reading command.

19. The interrogator according to claim 18, wherein an intensity level of a received data signal is detected when the wireless tag responds by the wireless communication using the reading command and the predetermined processing is performed only when the intensity level is equal to or greater than a minimum intensity level according to the identifier.

20. The interrogator according to claim 18, wherein the predetermined processing is a writing process for the wireless tag.
