Description

New IEEE Standard – Inactive-Reserved. This standard defines the air interface for radiating transceiver radio tags using long wavelength signals (kilometric and hectometric frequencies, <450 kHz). Conforming devices can have very low power consumption (a few microwatts on average), while operating over medium ranges (0.5 to 30 meters) and at low data transfer speeds (300–9600 bits per s). They are well suited for visibility networks, sensors, effectors and battery operated displays. This standard fills a gap between non-network-based RFID standards (e.g., ISO/IEC CD 15961-3, ISO 18000-6C or 7) and existing high bandwidth network standards such as IEEE Std 802. IEEE 802.15.4
