Phase Jitter Modulation (PJM) is a new modulation method specifically designed to meet the unique requirements of passive RFID tags. It has been adopted by the high frequency RFID Air Interface Standard ISO/IEC 18000-3 MODE 2 for high speed bulk conveyor fed item level identification because of its demonstrably higher data rates. The MODE 2 PJM data rate is 423,75 kbit/s; sixteen times faster than the alternative MODE 1 system ISO/IEC 18000-3 MODE 1 and the legacy HF system ISO/IEC 15693.
