The WS-RAM2-U925 adopts leading UHF RFID technology, operating at a frequency of 902–928 MHz (compliant with international standards), ensuring compatibility with mainstream timing systems. The antenna gain is approximately 8.5 dBi, providing a wide reading range and strong signal penetration. The standard 50 Ohm impedance design maximizes signal transmission efficiency. With an IP67 protection rating, it is waterproof and dustproof, adapting to harsh weather conditions. Its compact size of 1000 x 333 x 22 mm makes it lightweight and portable, and the ultra-thin 22mm design does not affect athlete performance.
