Referring now to FIGS. 5-6, there are provided illustrations that are useful for understanding certain advantages of the present solution. As noted above, the present solution provides RFID tags which can be read by a tag reader located farther away therefrom as compared to that of conventional systems. FIG. 5 shows a tag reader layout for a conventional system. In FIG. 5, there are 20 tag readers 502 with overlapping coverage areas 508. The distance 504, 506 between adjacent tag readers is relatively small (e.g., 9-15 feet apart). In contrast, FIG. 6 shows a tag reader layout for a system implementing the present solution. In FIG. 6, there are advantageously a significantly smaller number of tag readers 602 needed to cover the same area. Accordingly, the distances 606, 608 (e.g., 90-150 feet apart) between adjacent tag readers 602 is much greater than the distances 504, 506 of FIG. 5. Consequently, the present solution has a less resource intensive and less costly infrastructure.
