8.3.6 ISO/IEC 18000-3 mode 3/ EPC Class-1 HF functionality

The ISO/IEC 18000-3 mode 3/ EPC Class-1 HF is not described in this document. For a detailed explanation of

the protocol, refer to the ISO/IEC 18000-3 mode 3/ EPC Class-1 HF standard.

8.3.6.1 Data encoding ICODE

The ICODE protocols have mainly three different methods of data encoding:

• "1" out of "4" coding scheme

• "1" out of "256" coding scheme

• "Return to Zero" (RZ) coding scheme

Data encoding for all three coding schemes is done by the ICODE generator.

The supported EPC Class-1 HF modes are:

• 2 pulse for 424 kbit subcarrier

• 4 pulse for 424 kbit subcarrier

• 2 pulse for 848 kbit subcarrier

• 4 pulse for 848 kbit subcarrier
