摘要: 物联网期待泛在接入支持,包括使能和接入。HF RFID及其以前的RFID都只限于个体使能接入,现行UHF RFID 通过碰撞仲裁协议使物联网群体使能需求按序串行接入实施,依然属于个体接入方式。码分射频识别因其能抗标签碰撞和抗阅读器碰撞,又可通过选择适当的系统参数构建相应的系统模式,而能够满足物联网各类群体使能泛在接入需求。

Abstract: The Internet of Things expects ubiquitous access support, including enabling and access. HF RFID and its previous RFID are limited to individual enabling and access. The current UHF RFID makes the Internet of Things community enable the demand to be implemented sequentially through collision arbitration protocols, which is still an individual enabling and access method. Due to its ability to resist tag collisions and reader collisions, code division radio frequency identification can also build corresponding system modes by selecting appropriate system parameters, and can meet the ubiquitous access needs of various groups of the Internet of Things.
