ISO 18000-4 Mode 4Universal RFID system with
passive tag option
Reading range 8 m _at_ 100 mW Passage speed 200
km/h R/O and R/W tags Tag and reader
multiplicity 50 channels in 16 MHz
CRC 32 both on code and data lt1 uW energy
consumption in tag DES/RSA encryption
possible FHSS or CW operation Same protocol for
passive tags

ISO 18000-4 Mode 4Advantages over standardized
protocols
ISO 10374 (Containers) Mode 4 More efficient
coding (DPSK) Mode 4 No substitution errors (CRC
32) Mode 4 Tag multiplicity (random reply)
ISO TC278/TC204 (TICS) Mode 4 No wake-up
(running tag oscill.) Mode 4 More channels (50
ch / 16 MHz) Mode 4 Less tag energy (lt1 uW)
