Active RFID: A Deep Dive into Technology and Applications in China
Active RFID systems represent a significant advancement in radio-frequency identification technology. Unlike passive systems that rely on the reader for power, active RFID tags contain their own power source, typically a battery. This allows for longer read ranges, faster data transmission, and more complex functionalities. China, a global manufacturing and technological hub, plays a crucial role in the production and application of active RFID systems. This guide will explore the technology, its various types, and its widespread use across diverse sectors within China.
Understanding Active RFID Technology
The core of an active RFID system comprises three essential components: the tag, the reader, and the backend system. Active RFID tags, due to their self-powered nature, can transmit signals continuously, leading to significantly longer read ranges compared to passive tags. These ranges can extend up to 200 meters, as demonstrated by the 2.4GHz active RFID reader DL9130 from www.rfid-in-China.com. The reader receives these signals and transmits the data to a central system for processing and analysis. This backend system typically involves software for data management, analysis, and reporting. Shenzhen Goldbridge Industrial Co., Ltd. (www.Chinarfidfactory.com) highlights the importance of strong communication between suppliers and clients to ensure project success.
Technical Features of Active RFID Systems
