RFID applications in China's supply chain will still be dominated by HF

Analysys International data shows that HF tags accounted for about 60% of the RFID tag Market in 2005. At present, the application of RFID in China is still concentrated in LF and HF bands, mainly in non logistics fields. However, the application of logistics and supply chain is slowly increasing

Analysys International data shows that HF tags accounted for about 60% of the RFID tag Market in 2005. At present, the application of RFID in China is still concentrated in LF and h-band, mainly in the non logistics field. However, the application of logistics and supply chain is slowly increasing

analysis: at present, the main application bands of RFID in the logistics field are HF (high frequency) and UHF (ultra high frequency)

hf RFID reading and writing distance is generally 1m or less, but it is slightly longer than lf RFID, and its penetration ability is relatively strong. 10. Oil drainage: don't move anything in the pipe;, However, the signal will decay after penetrating the object. HF RFID has fast reading and writing speed and can read multiple tags at the same time

uhf RFID has the advantages of high energy, long reading and writing distance, generally more than 1m, typically 4~6m, up to more than 10m (with the strength of RF energy), and fast signal transmission speed

Analysys International believes that there are differences between the two:

1. Due to the strong direction definition and anti-collision algorithm, the passive RFID of UHF (900m and above frequencies) currently has problems of omission and misreading. At present, there is no product that can guarantee 100% reading rate, which limits the application of UHF Passive RFDI in logistics single product (usually large-scale) reading to a certain extent. HF reading distance is close, but in turn, it also ensures the accuracy of reading to the filter with infarct instigator

2. UHF RFID signals are easily blocked and cannot pass through many materials, including suspended particles such as metal, water, dust, fog, etc. There are still some defects in the application of complex logistics environment. HF is relatively good

3. The national standard of UHF RFID has not yet been issued, which has caused obstacles to the application of UHF logistics. In addition, uh has not recruited patients. F-band belongs to the national controlled band, and currently there is no allocation for RFID applications. Therefore, there are certain risks in the application of this band. HF does not have this problem

4. The domestic technology of HF RFID has been relatively mature, the localization level is high, and the cost is gradually reducing. UHF reading and writing equipment is relatively expensive

Analysys view

at present, RFID in China's logistics field is still a relatively high-end application. At present, the application is mainly based on mature technology and is very cost sensitive. Analysys International believes that in the application of supply chain, HF band is suitable for single products, with relatively mature technology, high reliability and relatively low cost; In terms of packaging, UHF band can be used to obtain longer distance reading and more flexible application. As our national logistics is still in the development stage, the most likely trend at this stage is to focus on the application demand of HF band and drive the increase of RFID demand of UHF band

however, Analysys International also believes that from the perspective of development trend, with the further maturity of UHF technology, it will become the mainstream application in the future logistics field
