Both UWB and RFID have their own traits. UWB stands out with advantages like centimeter-level positioning accuracy (around 0.1 – 0.3 m), which is much better than RFID’s. It enables data transmission while RFID can’t. With strong anti-interference, an ultra-low missed detection rate and high security, despite medium power consumption, UWB is highly competitive in high-precision tracking and secure data exchange scenarios, promising broad applications.
