RFID : ABSS Logistic EventTag Power Source Passive > Power by energy from reader > Backscatter technology > Smaller, Lighter, less expensive > Almost unlimited life > Shorter range > Requires higher power from reader Active > On-board battery power source > On-board transmitter > Greater range but higher cost > Requires less power from reader > Finite life
RFID : ABSS Logistic EventTag Power Source Semi-Active or Battery Assisted Passive > On-board battery power source > Uses Passive Technology (no transmitter) > Greater range but higher cost (less than active) > Requires less power from reader > Finite life (but longer than active) > Not create RF pollution
RFID : ABSS Logistic EventRead vs. Read/Write Read Only > Information can only be read from an RFID device – Programmed at manufacture User Programmable > WORM – Write Once Read Many, Ability to initialize an RFID device outside of the RFID manufacturer’s facility after manufacture Read/Write > Information can be read from or written to an RFID transponder during the time it is presented to a reader/writer > Typically asymmetric read and write operating range

RFID : ABSS Logistic EventFactors Effecting System Performance Distance (free space signal propagation) > Reader/receiver: transmit power, frequency, and range. > Antenna: transmit and receiving gain, pattern > Linear polarization > Circular polarization
RFID : ABSS Logistic EventFactors Effecting System Performance Distance (free space signal propagation) > Reader/receiver: transmit power, frequency, and range. > Antenna: transmit and receiving gain, pattern > Linear polarization > Circular polarization Interference > Other signal > Reader to reader interference > Adjacent channel Material in or near the signal path and device
RFID : ABSS Logistic EventRF Properties Radio Lucent or Radio Friendly > lets radio waves at this frequency pass through it without any substantial loss of energy Radio Absorbent > blocks, reflects, and scatters RF waves. Radio Opaque > A material can allow the radio waves to propagate through it but with substantial loss of energy > The RF-absorbent or RF-opaque property of a material is relative, because it depends on the frequency
