For the experimental setup,RFID systems with 13.56 MHz (high frequency) and passive RFID transponders were chosen,since HF transponders usually have a bigger memory size compared to ultra
high frequency (UHF) transponders.Furthermore,it is easier to have a limited and distinct communication area .

解答
在测验涩制中,射频系统处于13.56MHZ(高频)时,将调用RFID的接受器,因为 HF传输器一般来比UHF传输器拥有更多的存储量.同时,它还更容易控制相应的范围.
