3.4.4.3.2 Comparison with ISO 18000 Part 7
To understand and compare the complexity of different standards such as the ISO 18000
Part 7 and Part 6C, the RFID compiler has been used to implement commands from both
of them. A representative command, Query, was selected from ISO 18000 Part 6C and
has been implemented in hardware and synthesized for the ASIC target. Similarly, the
Collection command, which realizes similar functionality from ISO 18000 Part 7 standard,
was implemented in hardware and targeted to the same ASIC process. Table 3.6 shows the
power and area results for implementing these two commands. The Query command is
much larger and higher power consuming than the Collection command. We also compared
the Query command and the Collection command with nine additional primitives from the
ISO 18000 Part 7 standard. As shown in Table 3.6, the Query command is still larger and
higher power consuming than these 10 primitives from ISO 18000 Part 7.
3.4.4.4 ISO 18185 RFID Standard
The ISO 18185 Part 1 standard [45] is an international standard that provides a system for
the unique identi?¬?cation and presentation of information about freight container electronic
seals. It is used in conjunction with the other parts of ISO 18185 such as Part 4 that speci?¬?es
data protection and Part 7 that speci?¬?es the physical layer protocol.
