Current Situation and Future Trend of RFID-2.2 Use of weekly frequency bands

The usage of the ultra-high frequency band in various countries is 7. Unfortunately, the weekly frequency bands used in Japan, the United States, and Europe are different.

As mentioned above, UHF is the longest communication distance and can be used for unified reading of items in the supply chain. In international logistics, it is impossible to add RFID tags to each country that passes through circulation, the RFID tags developed in a region must be read from other regions. The economic and industrial province is conducting an experiment on RFID tags for the United States in Japan.

Currently, weekly wave numbers have been adjusted in some regions and can be used in all regions. In the future, the goal is to develop RFID tags that can communicate with each other in all regions.
