At present, common UHF RFID air interface protocols in China include international standards, national standards, industry standards, and corporate standards. The most popular standards are the 6C and 6D standards, namely ISO/IEC 18000-6C(63), ISO/IEC18000-6D(64), and the Chinese national standard GB/T 29768- which was officially implemented in May 2014. 2013.
The definition and coverage of UHF RFID frequency bands around the world are not the same, for example: China's frequency bands are 840~844MHz and 920~924MHz, EU frequency bands are between 865MHz~868MHz, Japan frequency bands are between 952MHz~954MHz, Hong Kong, Thailand, Singapore 920MHz~925MHz , The frequency band of the United States, Canada, Puerto Rico, Mexico, and South America is 902MHz~928MHz.
1. Environmental issues related to label application
Especially for UHF RFID products, metals and liquids have a greater impact on its performance. Therefore, whether the application environment is metal or non-metal, liquid or plastic, glass, wood, etc., is the first consideration.
The direct influence of raw materials on the radio frequency signal: metal has an influence on the radio frequency signal of the RFID tag. When used in metal objects or working environments with a lot of metal influence, you must use anti-metal electronic tags to reduce the influence of metal on the data signal of the tag. , To facilitate the normal use of RFID electronic tags.
The performance of UHF RFID tags is easily affected by the environment. If it is necessary to determine whether the product is suitable for the actual application environment, in the early test stage, the performance must be directly used for the object test to have reference value.
2. Factors affecting tag identification distance
The reading distance is also directly related to the reader and antenna. It is necessary to clarify the installation position and angle of the tag and the reader antenna. At the same time, parameters such as power selection, antenna gain, polarization mode, and radiation angle are all categories that need to be considered.
In the entire RFID system, every detail may affect the actual reading distance, and whether it can finally meet the project requirements, even the length of the feeder (the cable connecting the antenna and the reader) needs to be considered.
Three, understanding of the size of the label
In our past experience of many projects, customers often hope that the label size is small, so that it is both good-looking and easy to install.
However, the size of the label is precisely one of the main factors that determine the performance of the label. Generally speaking, the larger the size, the better the label performance can be designed. Different manufacturers, different models and specifications, integrated IC production technology and antenna manufacturing technology, there are certain differences in prices, consumers should follow The actual usage and cost budget are selected.
Four, other considerations
In addition, there are other detailed considerations, such as: Does the label have environmental reliability requirements such as temperature and humidity resistance? How much data capacity does the label need to write? What is the maximum number of tags that need to be read at one time? etc...
RFID Label can be widely applied in identification, public transportion , event ticketing electronic toll collection, asset
management ,libraries and rental, loyalty system and access control management etc. Besides, Nexqo provides programming and encoding services which exactly fit customer’s programming or encoding requirements.
