ISO 18000-4
ISO/IEC 18000-4:2018 - Information technology - Radio frequency identification for item management - Part 4: Parameters for air interface communications at 2.45 GHz
Overview
Defines the air interface for RFID systems operating at 2.45 GHz (microwave). This frequency supports higher data rates and is used in active and semi-active RFID systems for real-time location (RTLS), vehicle tolling, and container tracking. Less common than UHF for passive tagging due to shorter passive range and higher tag cost.
Why it matters for RFID
Covers the 2.45 GHz RFID frequency band used in active tag systems and real-time location. Important for understanding the full RFID frequency spectrum beyond LF, HF, and UHF.
