As mentioned before, command interaction communication methods are used in many scenarios. For example, passive IoT technology based on backscattered ultra-high frequency RFID has the characteristics of wide coverage, low cost, and accurate positioning. It has a wide range of applications, including Retail, industry, electric power, medicine, animal husbandry, logistics and other industries.

In 1995, the International Organization for Standardization Joint Technical Committee established a subcommittee (hereinafter (referred to as "SC31"), responsible for RFID standardization research work. Based on the RFID standard content formulated by the International Organization for Standardization (ISO), the RFID application standard is based on basic standards such as RFID coding, air interface protocol, reader/writer protocol, etc., and determines the usage conditions, Specific specifications for specific application requirements in terms of label size, label affixing location, data content format, frequency band, etc., as well as other requirements such as data integrity and manual identification. General standards provide a basic framework, and application standards supplement and specify it. This standard-setting idea not only ensures the interoperability and interoperability of RFID technology, but also takes into account the characteristics of the application field, and can well meet the specific requirements of the application field.

Take the RFID air interface protocol ISO-18000-6B/6C series as an example. The RFID protocol adopts the interactive method of commands. For example, communication device 1 (such as a reader) asks first, and communication device 2 (such as a tag) answers later. The way.
