Abstract :
A novel multi-protocol RFID reader with automatic power control is proposed in this paper based on a software defined radio architecture. The transponder power consumption variation over time is considered for different protocols. The modulation effect of power control on forward data transmission is included in the analysis. The emission power of the reader is automatically tuned in real-time according to the needs of the transponders in compliance with different standards, with which a considerable amount of power can be saved.
