RFID technology is expected to become a new profit growth point

as a new wireless identification technology, RFID technology is expected to become a new profit growth point in the communication industry within 3 to 5 years

since 2004, RFID has suddenly become a hot spot, attracting the attention of the media, industry, government and even consumers. According to the prediction of insiders, the RFID technology market will bring us $3-10 billion business opportunities in new products and services in the next five years, followed by the huge demand for servers, data storage systems, database programs, business management software, consulting services, and other computer infrastructure

perhaps these predictions are too optimistic, but there is no doubt that RFID will become a huge market in the future. Many high-tech companies are stepping up the development of RFID specific software and hardware, including Intel, Microsoft, Oracle, sap and sun. Therefore, it can be said that radio frequency identification technology (RFID) is becoming a global hot new favorite

RFID technology has become a new favorite in the world

RFID is the abbreviation of radio frequency identification, that is, radio frequency identification technology. The so-called radio frequency identification technology is a technology that uses radio frequency signals to realize contactless information transmission through spatial coupling (alternating magnetic field or electromagnetic field) and achieves the purpose of identification through the transmitted information. In fact, it is not a particularly advanced technology, which has been studied as early as the 1950s. Its core component is an electronic tag with a diameter of less than 2 mm. Through the radio waves emitted by the sensors within a distance of several centimeters to several meters, it can read the information stored in the electronic tag and identify the identity of the items, appliances and people represented by the electronic tag

generally speaking, in the specific application process of RFID system, the composition of the system will be different according to different application purposes and application environments, but from the working principle of RFID system, the system is mainly composed of signal transmitter, signal receiver and transmitting and receiving antenna. According to the different functions of RFID system, RFID system can be roughly divided into four types: EAS system, portable data acquisition system, network system, its fracture shape is bowl system, positioning system. RFID is widely used because of its data reading and writing function, easy miniaturization and diversification of shape, environmental resistance, reusability, penetrability and large memory capacity of data, The most common applications are: access control, asset recycling, cargo management, material treatment, waste treatment, medical applications, transportation, anti-theft applications, animal monitoring, automatic control, joint tickets, etc

of course, the application field targeted by RFID is different from other wireless technologies, because RFID requires fast, real-time and frequent data exchange, so as to effectively solve the urgent social problem of recycling and processing of composite products such as aluminum-plastic composite film, aluminum-plastic plate, plastic composite film, optical cable and cable, so as to ensure data security, and its data flow is also very large, Therefore, higher requirements are put forward for the bandwidth of wireless data communication. Technically speaking, cooling device: after the molded plastic extruded layer leaves the machine head, the future RFID technology application needs 3G or higher technology to provide more powerful communication service support, because the current communication is difficult to support the application of RFID in terms of data flow and data security, and 3G technology can provide users with high-speed data transmission at a lower price and a safer mechanism, And it can also support more colorful data services, which can meet the application needs of RFID in the future. It is conceivable that if RFID is combined with 3G, it will provide a very good value chain. On this value chain, content providers provide detailed commodity data information, service providers provide rich application platforms and programs, and communication equipment suppliers develop high-performance terminal products and communication equipment, Communication operators build the high-speed channel of RFID data, and conductive thermoplastic materials can be widely used in color matching products

from the current trend, RFID will be popularized in China soon. It can be said that the market of RFID products in China is very huge. At present, RFID technology has been used in some places in China

rfid international standards have not been completed.

due to the complex links involved in the RFID industrial chain and its attractive market application prospects, all countries want to develop and promote their own standards, so that they can not only obtain patents for high-tech technical standards, but also obtain the greatest economic benefits and technical protection from them. Therefore, at present, the international standards of RFID have not been completed, and there are only some industry standards

according to the specifications of the International Telecommunication Union (ITU), there are six kinds of frequencies used by RFID at present, which are below 135KHz, 13.56MHz, 433.92mhz, 860m-930mhz (UHF), 2.45GHz and 5.8GHz respectively. They have their own characteristics and defects. Therefore, it is inevitable that the existing user frequency will be shifted, otherwise the management blind spot will inevitably appear in the cross region application. For example, the transmission distance below 135KHz is about 10 cm short, and the communication speed is slow; The best transmission distance of 13.56MHz thinning is less than 1 meter; RFID tags in UHF band can reach a transmission distance of nearly 5 meters at most. Therefore, standardization is a necessary measure to promote products to be widely accepted by the market. In fact, only through standardization can RFID technology have the opportunity to usher in its own "future". Therefore, companies, automatic identification centers and international standards organizations are working to develop standards for RFID tags, so that all tags can be compatible with any reader

China's attitude towards this standard is also to actively participate in and formulate corresponding domestic standards. In terms of frequency planning, which has attracted much attention, the latest news we know is that in order to do a good job in the division of RFID frequency resources, the radio administration of the Ministry of information industry has carried out a lot of research, specially organized personnel to carry out electromagnetic compatibility and related theoretical analysis of RFID, and conducted scientific simulation tests, In particular, the UHF band test team, which began last year, has made smooth progress, and has put forward appropriate RF parameter suggestions based on a large number of experimental data analysis and RF model simulation. However, this year, the test team will further organize forces to continue experimental simulation and the occupancy analysis of each spectrum, so as to ensure the optimization of the parameters of the final frequency band and the parameter specifications of the RF reader. The head of the frequency planning department of the radio administration bureau of the Ministry of information industry recently pointed out that the domestic management department will implement a mandatory "radio transmission equipment type approval system" for RFID products to avoid serious damage to the electromagnetic environment caused by some unqualified RFID products

in addition to the above standard problems, we should also see that while this technology brings convenience, it also generates some new problems, such as personal privacy and unemployment. But judging from the current trend, these seem to be unable to stop the "charm" of RFID, and RFID technology still has a bright future - there is no doubt that with the progress of technology, RFID will become more and more perfect

Editor's note: like new technologies such as "WiMAX", the investment risk of RFID can't be ignored. RFID may undergo a three-stage development cycle: first, there is a hype period, in which the technology is very hot, lifting the appetite of the market; Then, inflated expectations were shattered by reality, and technology fell into a "disillusionment trough"; Finally, after the benefits of technology are better understood and realized, the market enters a stable and mature stage. Therefore, the development of RFID is not risk-free

as the saying goes: it is the lack of a set of widely used standards that has prevented RFID technology from being widely used in supply chain management. When the data in one link of the supply chain cannot be used in the next link, the cost of technology development will increase significantly. It can be seen that a detailed, unified, standardized and open technical standard is the top priority for the development of RFID technology. (end)
