Abstract

Described is a system which includes a wireless arrangement and a mobile unit. The mobile unit includes a wireless transducer and a data acquisition arrangement (“DAA”). The DAA obtains identification data from a marker which is situated on a permanent fixture at a predetermined location. The wireless transducer sends a transmission to the wireless arrangement. The transmission includes the identification data and wireless transmission data. The wireless arrangement analyzes the identification data to determine the predetermined location. The wireless arrangement determines wireless coverage data at the location as a function of the transmission data.

Claims

1. A system, comprising:

a wireless arrangement; and

a mobile unit including a wireless transducer and a data acquisition arrangement (“

DAA”

), the DAA obtaining identification data from a marker which is situated on a permanent fixture at a predetermined location,

wherein the wireless transducer sends a transmission to the wireless arrangement, the transmission including the identification data and wireless transmission data, and

wherein the wireless arrangement analyzes the identification data to determine the predetermined location, the wireless arrangement determining wireless coverage data at the location as a function of the transmission data.

2. The system according to claim 1, wherein the wireless arrangement is one of an access point, a wireless hub and a wireless switch.

3. The system according to claim 1, wherein the mobile unit is one of a barcode scanner and an RFID interrogator.

4. The system according to claim 1, wherein the marker is one of a barcode and an RFID tag.

5. The system according to claim 1, wherein the wireless transmission data is at least one of a received signal strength indicator, a predetermined number of missed beacons, a predetermined number of cyclic redundancy check errors, a predetermined number of retransmissions, a ping data and a timestamp.

6. The system according to claim 1, wherein the transmission further includes mobile unit identification data.

7. The system according to claim 6, wherein the mobile unit identification data is at least one of a MAC address of the mobile unit and a service set identifier of the mobile unit.

8. The system according to claim 1, wherein the wireless coverage data is determined by a comparison of the transmission data and stored transmission data on the wireless arrangement.

9. The system according to claim 8, wherein the stored transmission data is a threshold value of at least one of a received signal strength indicator, missed beacons, cyclic redundancy check errors, retransmissions and ping data.

10. The system according to claim 9, wherein, when the transmission data is below the threshold value, the wireless arrangement indicates that a coverage gap exists at the predetermined location.

11. A method, comprising:

receiving a transmission generated by a mobile unit, the transmission including identification data and wireless transmission data, the identification data obtained from a marker situated on a permanent fixture at a predetermined location;

analyzing the identification data to determine the predetermined location; and

determining wireless coverage data at the location as a function of the transmission data.

12. The method according to claim 11, wherein the mobile unit is one of a barcode scanner and an RFID interrogator.

13. The method according to claim 11, wherein the marker is one of a barcode and an RFID tag.

14. The method according to claim 11, wherein the wireless transmission data is at least one of a received signal strength indicator, a predetermined number of missed beacons, a predetermined number of cyclic redundancy check errors, a predetermined number of retransmissions, a ping data and a timestamp.

15. The method according to claim 11, wherein the transmission further includes mobile unit identification data.

16. The method according to claim 15, wherein the mobile unit identification data is at least one of a MAC address of the mobile unit and a service set identifier of the mobile unit.

17. The method according to claim 11, wherein the determining step further includes:

comparing the transmission data and stored transmission data.

18. The method according to claim 17, wherein the stored transmission data is a threshold value of at least one of a received signal strength indicator, missed beacons, cyclic redundancy check errors, retransmissions and ping data.

19. The method according to claim 18, wherein the determining step further includes:

when the transmission data is below the threshold value, indicating that a coverage gap exists at the predetermined location.

20. A system, comprising:

a wireless arrangement; and

a mobile unit including a wireless transducer and a data acquisition arrangement (“

DAA”

), the DAA obtaining identification data from a marker which is situated on a permanent fixture at a predetermined location,

wherein the wireless transducer sends a transmission to the wireless arrangement, the transmission including the identification data and wireless transmission data, and

wherein the wireless arrangement analyzes the identification data to determine the predetermined location, the wireless arrangement determining an existence of a coverage gap at the location as a function of the transmission data.
