China RFID radio frequency planning and management

【 Summary 】 China has almost completed a low frequency, high-frequency, UHF and UHF band RFID technique of frequency planning for RFID technology application in China and the development of the radio frequency spectrum resource.

【 RFID radio frequency Express 2007 August 30 rising 】 Ministry of information industry, recently issued a publication 800/900MHz band radio frequency identification (RFID) technology to apply the provisions of notification law on a trial basis.

So far, China has almost completed a low frequency (LH), high-frequency (HF), super high frequency (UHF) and ultra high frequency (SHF) band RFID frequency planning for RFID technology application in China and the development of the radio frequency spectrum resource.

With the economic and social development and technological progress, RFID at present all aspects of social life has been or is about to play an important role in the circulation of goods, etc bring profound changes, and thus to the socio-economic, industry and market, a far-reaching impact.

Our radio Management Department has always attached great importance to RFID and other wireless sensing technology, frequency planning aspects of such technologies to support. Table 1 lists the currently planned for RFID frequencies.

Select a different frequency, mainly depends on the frequency of the radio propagation characteristics correspond to the RFID technology and working mechanism, table 2 lists the RFID technology individual working frequency bands correspond to the characteristics.

800/900MHz band RFID technology introduction of frequency planning

Radio frequency is important, limited strategic resources.

The real act People's Republic of China of the radio spectrum resource is used by the State. The radio frequency has been widely used in economic, social, safety, defence, and other fields, all kinds of radio new technology and new applications emerging on the limited spectrum resources raised more and more demand. Science of frequency planning is efficient and rational use of radio spectrum resources. According to the International Telecommunication Union (ITU) radio regulations and radio technology development trend in China's social departments, and industry demand for spectrum resources, last year officially released the revised provisions of the radio frequency allocation People's Republic of China, this file is for frequency planning of the most important basic guidance documents. In accordance with the provisions of the radio frequency allocation People's Republic of China and China's radio frequency of the actual use of the status quo, RFID technology needs and other radio technology or application sharing radio frequency. Therefore, frequency planning, the need to develop RFID and other wireless applications of common technical requirements and the relevant rules of procedure.

　　

　　

800MHz/900MHz band radio transmission performance and label size is moderate, suitable for antenna for long range identification and large-scale applications, the band RFID technology is the future "of networking", ubiquitous and heterogeneous future wireless communication network of important access technology vector.

In our country, 800/900MHz frequency bands allocated to public mobile communication, cluster communications, broadcasting, aeronautical navigation applications that involve the economy and national security. The band RFID frequency planning should ensure that RFID systems and existing wireless communication service of the electromagnetic compatibility of radio frequency coexistence and the efficient use of resources; development of RF parameters should ensure that RFID systems to large-scale, safe to use, and from all kinds of radio interference; the need for comprehensive consideration of RFID technology users ' requirements and interests of manufacturers, to contribute to international standards, taking into account the development of related industries in China.

Therefore, the frequency planning need to consider the allocation of working frequency and transmitter power, bandwidth, out-of-band emission, spurious emission, frequency tolerance, antennas and other radio frequency characteristics and the associated rules of radio managed programs.

In unification of the Ministry of information industry, under the leadership of two years, around the band RFID frequency planning, Ministry of information industry, national organization experts completed the electromagnetic compatibility analysis and testing; countrywide on 800/900MHz band occupancy for radio monitoring; repeatedly organized by Ministry of information industry Bureau, Government related to the relevant ministries, the army, the RFID standards organizations, production enterprises, research institutions and application sectors to participate in the Forum of frequency planning and in the form of a formal document sought the Standardization Management Board and the Ministry of information industry related electronic labelling working group.

According to the frequency of use of the actual situation and the relevant test results of the analysis, combined with China's relevant departments, and frequency planning expert Advisory Committee of experts considered that the recent planning out 840-845MHz and 920-925MHz band for RFID technology.

RFID technology-related provisions of the radio transmission equipment management

Under the radio regulations People's Republic of China, China on all types of radio transmission equipment type approval management.

Radio transmission equipment type approval management is on the development, production, importation, sale of radio transmission equipment in the frequency and electromagnetic compatibility specifications. It aims at the prevention of radio interference, maintain normal radio order to ensure that all types of radio services up and running.

According to the relevant administrative provisions, RFID radio device application by free radio licence management.

However, such devices must be passed by radio transmission equipment type approval test, and obtain the recounting of China's Ministry of information industry of radio transmission equipment type approval permit before in China, production, sale and use. China RFID radio transmitting equipment development, production and the consumer's obligation and responsibility to comply with the relevant provisions of the radio transmission equipment management.
