Study on RFID Communication Frequency Band Applied in Grains´ Circulations

The supervision and administration of grains circulation is national key R&D program. As a booming technology, RFID gives full play to its advantages in this area. Especially the integration with wireless communication devices and sensors, RFID can fulfill the task from grains´ purchasing, conveying, storing to product transaction. Considering the circulation´s complication, it is stringent to build different frequency bands´ RFID systems. But the criterion for selection of RFID frequency band is absent. Based on the requirements for RFID in modern grains logistics, this paper gives the reference selections of frequency bands, designed to form a standardized operation.
