RAIN RFID
RAIN RFID (UHF Passive ISO 18000-63)
Global alliance standard for passive UHF RFID operating at 860–960 MHz using the GS1 EPC Gen2v2 protocol, enabling battery-free read ranges up to 15 meters.
RSSI
RSSI (Received Signal Strength Indicator)
Measurement in dBm (typically -30 dBm strong to -90 dBm weak) reported by an RFID reader indicating backscattered signal power from a tag.
dBiC / CP
Circular Polarization (dBiC)
Antenna radiation pattern rotating in 360° corkscrew planes so RFID tags can be read reliably regardless of tag orientation on pallets or totes.
