Introduction
Have you ever heard of Radio Identification (RID) technology? It is often confused with Radio Frequency Identification (RFID) technology, but there are some significant differences that set them apart. In this blog post, we will compare these two technologies in terms of their operating frequencies, range, and applications.
Operating Frequency
RID technology operates at frequencies that vary between 30 and 300 MHz. While RFID operates at a higher frequency range of between 860 MHz and 960 MHz. RFID is also capable of operating at ultra-high frequencies up to 2.4 GHz.
Range
RID has a relatively limited range of about 200 meters. On the other hand, RFID technology can have a range of up to 100 meters for passive tags and up to 300 meters for active tags. This range advantage of RFID makes it ideal for distance applications.
Applications
RID technology is mostly used in long-range communication applications, such as controlling military drones, remote meter reading, and transmission of large amounts of data. RFID technology, on the other hand, is used in applications such as inventory management, asset tracking, and access control.
Conclusion
Despite some similarities between RID and RFID technology, they have significant differences in terms of operating frequencies, ranges, and applications. It's crucial to understand these differences when choosing the right technology for specific applications.
