在本文中，我们描述了一种新的无源RFID系统，能够直接标签到标签的通信中存在的外部射频场。标签通过调制外部场并因此将命令反向散射到彼此来进行交谈。我们提出了系统的概念，并显示其硬件实现的TI MSP430微控制器的基础上。我们还提供了调制深度与距离的理论模型，与实验结果（最大标签到标签通信距离）一致。最后，我们讨论了可能的应用程序和未来的工作。
In this paper, we describe a novel passive RFID system capable of direct tag-to-tag communication in the presence of external radio frequency field. Tags talk by modulating the external field and thus backscattering the commands to each other. We present the system concept and show its hardware implementation based on TI MSP430 microcontroller. We also provide the theoretical model for modulation depth vs. distance which agrees with experimental results (maximum tag-to-tag communication distance). Finally, we discuss possible applications and outline future work.
