RFID Technology And EMC Analysis

In recent years, with the development of wireless communications, computermicroelectronics, and network technology, Internet of Things technology becomemore and more popular, Gradually become the focus of widespread concern at homeand abroad.At present, the development of China’s Internet of Things and the global in itsinfancy, initially with a certain technology, industry and application base, showing agood momentum of development, RFID (radio frequency identification) industrymarket size of more than100billion yuan, low-frequencyand high-frequency RFID isrelatively mature, but widely used in logistics, transportation and other importantareas of UHF and microwave RFID core technologies and key products than indeveloped countries there is a big gap.RFID technology is very important for internet of Things, and widely used in ourlife. so far, China has not yet formed technical requirements and testing standards.This paper first introduces the basic concepts and history of the development ofRFID, Then explore the general method of electromagnetic compatibility test, throughthe Tianjin radio stations EMC laboratory testing experience, with reference to therelevant technical standards at home and abroad and understanding RFID technologyand electromagnetic compatibility, design and implementation of a series of scientificexperiments, RFID frequency band used in China125KHz,13.56MHz,433MHz,860-960MHz and2.45GHz band, electromagnetic compatibility test will bebased on the actual situation of our country in the adjacent band radio system to carryout in the laboratory and practical applicationscene detection of RFID equipment tomeasure the different frequency bands, the RFID devices spurious, RFID and otherequipment EMC.
