Feasibility study of low power active RFID system based on the ultrasonic frequency

초음파를 이용한 저전력 Active RFID시스템의 구현가능성에 관한 연구

This paper proposes the possibility of SonicID system which is the active RFID based on the ultrasonic spectrum instead of using radio frequency. For the feasibility study, various performance indexes are measured in terms of power consumption and signal path loss onto the frequencies of 40KHz, 433MHz, and 2.4GHz. In addition to the line of sight condition, realistic situations are considered for diverse deploying environments. The results of these analyses demonstrate that the SonicID holds the potential to meet the needs of future advanced RFID system in a scalable fashion.
