射频技术在物联网中的应用

Application of RF Technology in Internet of Things

物联网可利用RFID技术,通过开放性的计算机网络实现信息的交换和共享,实现对物品的"透明"管理。RFID射频识别隶属于非接触式自动识别技术。其基本原理是利用射频信号和空间电磁场耦和传输特性来实现对监控物体的信息交换及自动识别。RFID的设计就是射频电路技术、通信技术、传感器技术等的紧密结合。

The essence of the Internet of things is the application of RFID technology, which realizes information exchange and sharing through open computer networks and achieves the transparent administration for the objects. RFID radio frequency identification belongs to a non-contact automatic identification technology. RFID system is widely used in the industry and commerce. The basic principle of RFID systems is to use radio frequency signals, electromagnetic field coupling and transmission characteristics to achieve the information exchange and automatic recognition of monitoring objects. RFID is a close integration of radio frequency circuit design technology, communication technology and sensor technology.
