Abstract

Describes 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 bps).
