WIRLESS TAG BASED COMMUNICATION, SYSTEM AND APPLICAITONS

1 . A method for detecting a presence of a tagged item within a tagged enclosure, the method comprising performing distance measurements between at least one wireless tag of the tagged enclosure and the tagged item to determine the spatial relationship between the tagged enclosure and the tagged item.

2 . The method according to claim 1 comprising determining, based upon the distance measurements, whether the tagged item is within the tagged enclosure.

3 . The method according to claim 1 comprising evaluating a location of a tagged user device in relation to the tagged enclosure by evaluating distances between at least two wireless tags of the tagged enclosure and the tagged user device.

4 . The method according to claim 1 further comprising transmitting to a wireless reader the outcome of the distance measurements.

5 . The method according to claim 1 wherein the performing of the distance measurements between at least one wireless tag of the tagged enclosure involves determining whether the tagged item is within a coverage area of each one of the at least one wireless tag.

6 . A non-transitory computer readable medium that stores instructions that once executed by a computer cause the computer to execute the stages of performing distance measurements between at least one wireless tag of a tagged enclosure and a tagged item to determine the spatial relationship between the tagged enclosure and the tagged item.

7 . The non-transitory computer readable medium according to claim 6 that stores instructions for determining, based upon the distance measurements, whether the tagged item is within the tagged enclosure.

8 . The non-transitory computer readable medium according to claim 6 that stores instructions for evaluating a location of a tagged user device in relation to the tagged enclosure by evaluating distances between at least two wireless tags of the tagged enclosure and the tagged user device.

9 . The non-transitory computer readable medium according to claim 6 wherein the performing of the distance measurements between at least one wireless tag of the tagged enclosure involves determining whether the tagged item is within a coverage area of each one of the at least one wireless tag.

10 . A wireless reader that comprises an interface and a processor, wherein the interface is arranged to receive distance measurements between at least one wireless tag of a tagged enclosure and a tagged item and wherein the processor is arranged to determine the spatial relationship between the tagged enclosure and the tagged item in response to the distance measurements.

11 . The wireless reader according to claim 10 wherein the processor is arranged to determine, based upon the distance measurements, whether the tagged item is within the tagged enclosure.

12 . The wireless reader according to claim 10 wherein the processor is arranged to evaluate a location of a tagged user device in relation to the tagged enclosure by evaluating distances between at least two wireless tags of the tagged enclosure and the tagged user device.

13 . The wireless reader according to claim 10 wherein the processor is the distance measurements are indicative of whether the tagged item is within a coverage area of each one of the at least one wireless tag.
